Interstate 210 California

 

A brand new California 210 reassurance shield was posted on westbound California 210 between Exit 73, State Street/University Parkway and Exit 71, Riverside Avenue between Muscoy and Rialto. This section was available for walkers and bicyclists on the "Come Play on the Freeway" event on June 24, 2007; the segment opened to traffic on July 24, 2007. Photo taken by Andy Field (06/24/07).

Routing

Interstate 210 in California is the Foothill Freeway between Interstate 5/Golden State Freeway in Sylmar and California 57/Orange Freeway in Glendora via Pasadena. At California 57, Interstate 210 changes into California 210, and the state highway continues east from there to San Bernardino, ending at Interstate 10 in Redlands. The section between Interstate 215 and Interstate 10 is still signed as California 30, but California 210 shields are being added along the older section of the route.

Future Aspirations

Plans call for the addition of the entire California 210 freeway to the existing Interstate 210 from San Dimas east to Redlands upon completion of the last segment of freeway, which is expected in 2007. The process to add former California 30 to Interstate 210 began in 1998, when the designation of California 30 was legislatively changed to California 210. Then on November 6, 1998, the state of California submitted California 30 for inclusion in the Interstate Highway System. AASHTO rejected this proposal because the freeway segments were not complete; however, the freeway will be resubmitted for approval once it is complete. It is not clear when the request to sign Interstate 210 will be made by Caltrans, but it could occur as soon as the next AASHTO Route Numbering Subcommittee Meeting.

History

Interstate 210/Foothill Freeway was planned in the 1940s, commissioned in the mid-1950s, and completed in stages through the 1960s, 1970s, and 1980s. California 210 (the state route section east of California 57) was completed in July 2007. As portions were completed, parts were signed as California 118 northwest of Pasadena and U.S. 66 east of Pasadena according to maps from that era. Once the significant portions of the route were completed, Interstate 210 markers were erected.

With the opening of the final link of California 210 on July 24, 2007,1 the combination of Interstate 210, California 210, and California 30 offer a continuous freeway link from Los Angeles (San Fernando Valley) to Redlands. It is not clear when the California Department of Transportation (Caltrans) will request an Interstate 210 designation for the entire freeway route.

Prior to the conversion of the former California 30 corridor into California 210 in 1999, a short section of Interstate 210 used to extend from the current California 57 and California 210 interchange in San Dimas south to the Kellogg Interchange (Junction Interstate 10/San Bernardino Freeway, California 57/Orange Freeway, and California 71/Corona Expressway) in Pomona. The section of Former Interstate 210 between these two points is now signed as California 57/Orange Freeway and is legislatively part of California 57. This truncation was performed in preparation for the conversion of California 210 into Interstate 210 after the freeway is completed through Rialto and Muscoy in July 2007 and after the American Association of State Highway and Transportation Officials (AASHTO) approves designating California 210/30 as Interstate 210.

This new California 210 was created in 1999 as the designation for the new freeway along the California 30 corridor between Interstate 210 in San Dimas and Interstate 10 in Redlands. A portion of this route, as of 2002, has already been completed, including the segment through San Dimas, the section through Upland and Rancho Cucamonga, and the existing California 30 freeway through San Bernardino and Highland. The completed freeway segments are signed as California 210, although some California 30 signs remain along the stretch between Interstate 215 and Interstate 10 around San Bernardino. The only remaining incomplete section is between Interstate 15 and Interstate 215, and that freeway should be open by 2007. Upon completion of the freeway, California 210 will be submitted to AASHTO for inclusion in the Interstate Highway System as an extension of Interstate 210.

Regarding the Interstate 5/Interstate 210 connector ramps, Adam Twiss indicates that the West to South Connector (from west Interstate 210 to south Interstate 5) along with the rest of the Interstate 5, Interstate 210, and California 14 interchanges were originally constructed in 1970-71 and were about to open when the Sylmar (San Fernando) Earthquake hit on February 9, 1971. Damages to this structure illustrates the severity of the event. On the day of the earthquake, the original South Connector fell on a pickup killing two people on the Golden State Freeway. The portion of Interstate 210 from Interstate 5 to Paxton Street was severly damaged in 1971 delaying the opening of this section, and the fault that caused the earthquake ripped through the freeway northwest of Maclay Street. This included the westbound onramp and eastbound offramp. There is a slight hump on the number three lane on the eastbound side - a slight offset near where the asphalt and concrete meet and also at the curb. This earthquake also buckled the Golden State Freeway just south of the San Fernando Road overcrossing.5

More on the California 30 north-south section of freeway from Scott Parker:

    Prior to the spring of 1992, when the full facility was completed, California 30 -- west to east -- looked like this: freeway to the present Highland Ave. interchange in east San Bernardino, east on Highland to Boulder Avenue (the California 30/330 intersection), where it turned south. It went south on Boulder to 5th, then turned west on 5th to the freeway alignment, then went south again over the eastbound two lanes across the Santa Ana River watercourse, extending south to San Bernardino Avenue in Redlands. At that point, traffic was shunted off onto that street east to the east side of the freeway berm, where it turned south onto Tennessee Street (which had been extended north circa 1982-83 to serve as a frontage road for the California 30 freeway, as it does today) and thence to the Interstate 10 interchange.

    Some maps of that era showed California 30 temporarily extending east all the way to Orange Street (the original state highway alignment) then south to California 38 at Lugonia Street, where it terminated. While this may have been the officially designated alignment (Caltrans ceded the part of Orange Street that dipped into the Santa Ana River bed over to the local jurisdiction), signage from California 30 east directed traffic heading to Interstate 10 directly down Tennessee Street (and, if you have been that way and paid notice, there is room on the overhead signage for the Tennessee St. exits on Interstate 10 -- in both directions -- for a state highway shield).

    Signage from Interstate 10 to California 30, if my memory from the mid eighties serves me correctly, was rudimentary at best: I seem to recall nothing indicating California 30 at the Interstate 10/California 38/Orange Street interchange in central Redlands, but one solitary stand-alone sign before the Tennessee Street offramp reading, from top to bottom "TO", California 30 (shield), "NEXT RIGHT" in a small square green sign under the shield. And that didn't last long, since that was also the site of construction of the Interstate 10/California 30 interchange, and the shield sat where Interstate 10 was being widened to accommodate the two-lane ramp exit to California 30.3

On November 6, 1998, AASHTO disapproved the extension of Interstate 210 from San Dimas east to Interstate 10 in Redlands via former California 30 because the freeway route was not yet complete. For now, sections of California 30 west of San Bernardino have been re-signed as California 210, while other sections of California 30 east of San Bernardino are still signed as California 30. It is anticipated that California will resubmit Interstate 210 to AASHTO once the California 210 freeway is complete in 2007.

At the same meeting in 1998, AASHTO also denied the removal of the section of Interstate 210 between Interstate 10 and California 30 from the Interstate Highway System. Nevertheless, this section was legislatively changed (by act of the state legislative bodies and signed into law by the governor) to an extension of California 57. As such, it is signed as California 57 in both directions, and signage for Interstate 210 ends at the California 57, California 210, and Interstate 210 interchange.

The last segment of California 210 opened on July 24, 2007, through Rialto and Muscoy.1 California 30 signs and shields were removed in favor of California 210 signs and shields in Fall 2007.

Highway Guides

Western Terminus - Interstate 5 - Los Angeles (Sylmar), California
Perspective from Interstate 210/Foothill Freeway west
Traveling west on Interstate 210/Foothill Freeway, this mileage sign shows the distance to the cities of Santa Clarita, Bakersfield, and Sacramento. Of these cities, all of them require a drive on Interstate 5 north, with Bakersfield located on California 99 in the Central Valley. Interstate 210 does not extend any further than Interstate 5; however, motorists wishing to reach Simi Valley or points northwest (such as Santa Barbara) should use California 118/Ronald Reagan (Simi Valley) Freeway. Photo taken by Andy Field (07/03/04).
Westbound Interstate 210/Foothill Freeway reaches Exit 3, Polk Street. This is the first exit after the aforementioned mileage sign. Photo taken by Andy Field (07/03/04).
The next exit along westbound Interstate 210/Foothill Freeway is Exit 2, Roxford Street to Sylmar (a community of the city of Los Angeles). Photo taken by Andy Field (07/03/04).
An upcoming exits mileage sign provides the distance to the final exits on Interstate 210 west: Exit 2, Roxford Street; Exit 1C, Yarnell Street; and Exits 1B-A, Junction Interstate 5/Golden State Freeway. Photo taken by Andy Field (07/03/04).
Use the right lane to connect to Roxford Street (Exit 2). Photo taken by Andy Field (07/03/04).
Westbound Interstate 210/Foothill Freeway reaches Exit 2, Roxford Street to Sylmar. Continue straight ahead to follow Interstate 210 west to Interstate 5. Photo taken by Andy Field (07/03/04).
The penultimate exit on Interstate 210 west (before the Interstate 5 interchange) is for Exit 1C, Yarnell Street. Photo taken by Andy Field (07/03/04).
A final upcoming exits mileage sign is posted shortly thereafter, and it provides the distance to the final exits on Interstate 210/Foothill Freeway west: Exit 1C, Yarnell Street; Exit 1B, Junction Interstate 5/Golden State Freeway; and Exit 1A, Junction Interstate 5/Golden State Freeway and California 14/Antelope Valley Freeway Truck Route north. Photo taken by Andy Field (07/03/04).
Westbound Interstate 210 reaches Exit 1C, Yarnell Street. The next exits are: Exit 1B, Junction Interstate 5/Golden State Freeway south to downtown Los Angeles and Exit 1A, Junction Interstate 5/Golden State Freeway north to California 14. Exit 1A will subdivide into main lanes and truck lanes for northbound Interstate 5 and California 14. Photo taken by Andy Field (07/03/04).
The right lane (incoming onramp from Yarnell Street) becomes exit only for the connection from Interstate 210/Foothill Freeway west to Interstate 5/Golden State Freeway south to downtown Los Angeles. These porcelain-enamel signs date back to the opening of this section of the Interstate 210 freeway. Photo taken by Andy Field (07/03/04).
A reflective roadside sign again advises that the next right is the connection to Interstate 5/Golden State Freeway south to downtown Los Angeles. Photo taken by Andy Field (07/03/04).
An END Interstate 210 shield is posted shortly thereafter. Caltrans District 7 is fairly good about placing END shields on its 1960s-1970s freeways; other examples of END shields include the north end of Interstate 605 and the north end of California 170. However, there are no END shields for Interstate 105, which was completed in 1993. Photo taken by Andy Field (07/03/04).
Westbound Interstate 210 splits here: the right lanes connect to Interstate 5/Golden State Freeway south, and the left lanes connect Interstate 5/Golden State Freeway north to California 14/Antelope Valley Freeway. Named the Golden State Freeway through the San Fernando Valley, Interstate 5 follows Historic U.S. 99 as it crosses over the Tejon Pass en route to the Central Valley. At Wheeler Ridge, Interstate 5 splits west along the Westside Highway while California 99 takes over the Golden State Freeway on its way to Bakersfield and Fresno. Photo taken by Andy Field (07/03/04).
Following the ramp to Interstate 5 north (Exit 1A), the massive Golden State Freeway and the Newhall Pass Interchange (Junction California 14) come into view. Note the signs indicate that trucks must use the truck bypass if heading north on Interstate 5; exit right here onto the truck bypass. Cars should stay left and prepare to merge onto the main lanes. The interchange with California 14/Antelope Valley Freeway is signed from this interchange for traffic headed toward the Antelope Valley (Lancaster and Palmdale in northern Los Angeles County), Mojave, and the Eastern Sierra via U.S. 395 north. Photo taken by Andy Field (07/03/04).
Perspective from Interstate 5/Golden State Freeway north
The first indication of the upcoming interchange with Interstate 210 appears immediately after traffic from northbound Interstate 405 (San Diego Freeway) merges onto Interstate 5. This mileage sign advises that the transition ramp to eastbound Interstate 210 is 1.75 miles ahead, just prior to the California 14 (Antelope Valley Freeway) split. Photo taken by AARoads (11/25/04).
There is one intervening exit between Interstate 405 and Interstate 210: Exits 159A-B, Roxford Street. Photo taken by AARoads (11/25/04).
Northbound Interstate 5 reaches the exit for Roxford Street (Exits 159A-B). The next exit along northbound is the transition ramp to Interstate 210 east, which travels around the city of San Fernando, then follows the Foothill Freeway southeast to Pasadena and San Bernardino County. Photos taken by Andy Field (08/26/07) and AARoads (11/25/04).
An overhead sign advises of the truck bypass exit for the right two lanes; this exit is part of the California 14 interchange complex, which begins immediately after the Interstate 210 exit. Photo taken by AARoads (11/25/04).
The next mileage sign along northbound Interstate 5 is for Exit 161A, Junction Interstate 210, followed by the Truck Lane offramp (Exit 161B). Both the main lanes and the truck lanes offer a connection to California 14, the Antelope Valley Freeway, which travels northeast toward Lancaster, Palmdale, and Mojave. Since most traffic is going to continue on Interstate 5 or exit onto California 14, Interstate 210 is almost an afterthought. Not too many cars opt to take Interstate 210/Foothill Freeway, since it travels southeast from here. Photo taken by AARoads (11/25/04).
Northbound Interstate 5 reaches Exit 161A, Junction Interstate 210 near Sylmar at the north end of the San Fernando Valley. Note the replacement signage with the exit number. This area is heavily industrialized, with significant concentrations of power, water, and natural gas facilities. A large pump that carries Los Angeles Aqueduct water over the mountains is present to the northeast of here, and a wide assortment of power lines feed into this area, including the main north-south line from the Central Valley, several lines from Hoover Dam, and another set from Owens Valley. Photos taken by Andy Field (08/26/07) and by AARoads (11/25/04).
Shortly after Interstate 210 splits off to the east, Interstate 5 north splits into auto and truck bypass lanes. All trucks must use the truck bypass (right two lanes). The left four lanes continue north on Interstate 5/Golden State Freeway to California 14/Antelope Valley Freeway. The overhead ramps in this photo are the Interstate 210 connectors, almost forming a tri-level stack interchange. The top ramp connects Interstate 210 west to Interstate 5 south, while the bottom ramp connects Interstate 5 south to Interstate 210 east. Photo taken by Andy Field (08/26/07).
Perspective from Interstate 5/Golden State Freeway south (Main Lanes)
Now traveling south on Interstate 5 (the Golden State Freeway), the first appearance of Interstate 210 is found on this overhead upcoming exits mileage sign after the California 14/Antelope Valley Freeway ramp. Photo taken by Andy Field (08/26/07).
The next exit on Interstate 5/Golden State Freeway south is Exit 161B, Balboa Boulevard and San Fernando Road. Prior to the completion of the Golden State Freeway, San Fernando Road was the main route to downtown Los Angeles and was signed as U.S. 99. San Fernando Road was briefly signed as Business U.S. 99 and Business Loop I-5 before the street was signed as Historic U.S. 99. Photo taken by Andy Field (08/26/07).
Passing through the California 14 interchange, a Los Angeles city limits sign is posted prior to Exit 161A. The western terminus of Interstate 210 is located in the city of Los Angeles. Photo taken by Andy Field (08/26/07).
Interstate 210 travels southeast from Interstate 5 to Pasadena, then turns east to San Bernardino. While Interstate 210 directly replaces California 30, it is also parallel to the former alignment of U.S. 66 between Pasadena and San Bernardino. Photo taken by Andy Field (08/26/07).
Southbound Interstate 5/Golden State Freeway reaches Exit 161B, Balboa Boulevard and San Fernando Road (Historic U.S. 99). A bridge carries the ramp for this exit over the truck lanes. The next exit is for Interstate 210 east. Photo taken by Andy Field (08/26/07).
A roadside sign marks the 0.75-mile distance to the Interstate 210 exit. For a major Interstate highway interchange, it seems like more overhead signs would be posted here. Photo taken by Andy Field (08/26/07).
An overhead guide sign might be more appropriate to show the lane allocation for Interstate 210 east. The right two lanes of Interstate 5 south will become exit only for Interstate 210 east. It is possible that a new overhead sign would be placed here once the project for new high occupancy vehicle lanes is complete - an overhead sign used to be placed here before the recent addition of lanes. Photo taken by Andy Field (08/26/07).
The judicious use of green overlays betrays the true age of this sign: It is over 40 years old, and it is likely porcelain enamel with raised button copy. The sign is not reflective and is lit at night to aid visibility. With the ongoing sign replacement program in California, many of these historic signs are being replaced with reflective signs. While it's easier to read the reflective signs and we support the sign replacement, the historical side suggests that it is a shame to see this piece of history removed from California's highways. Photo taken by Andy Field (08/26/07).
Southbound Interstate 5/Golden State Freeway reaches Exit 161A, Junction Interstate 210/Foothill Freeway east to San Fernando, Pasadena, and San Bernardino. The exit is two lanes, so the left four lanes (plus eventual high occupancy vehicle lane) continue south on Interstate 5. This sign replaces the original porcelain enamel sign; the reflective sign was mounted probably in 2006 or 2007. Note that this is the first exit sign for Interstate 210 to feature an exit number. Photo taken by Andy Field (08/26/07).
The interchange between Interstate 5 and Interstate 210 provides movements in all directions; the two flyovers here connect southbound Interstate 5 to eastbound Interstate 210 and connect westbound Interstate 210 to southbound Interstate 5. Due to the 1971 Sylmar (San Fernando) earthquake, the Interstate 210 west to Interstate 5 south connector collapsed, and it was not rebuilt until 1975. A pair of high voltage (500 kV) power lines cross over the center of the interchange (the wires are suspended above the freeway). Photo taken by Andy Field (08/26/07).
Perspective from Interstate 5/Golden State Freeway south (Truck Lanes)
As seen from the truck lanes, there are no advance signs for the Interstate 210 split until the gore point. Photo taken by AARoads (09/25/05).
Southbound Interstate 5 Truck Lanes reach Exit 161, Junction Interstate 210/Foothill Freeway east to Pasadena and San Bernardino. Photo taken by AARoads (09/25/05).
Perspective from Interstate 210/Foothill Freeway east
Now traveling east on Interstate 210 after the Interstate 5 interchange, the first upcoming exits mileage sign provides the distance to the first three exits: Exit 1, Yarnell Street; Exit 2, Roxford Street; and Exit 3, Polk Street. Photo taken 11/14/04.
This is the first reassurance shield for Interstate 210 east. Photo taken 11/14/04.
Eastbound Interstate 210/Foothill Freeway reaches Exit 1, Yarnell Street. The next interchange is Exit 2, Roxford Street. Photo taken 11/14/04.
Current Eastern Terminus - California 57 - Glendora, California
Perspective from Interstate 210/Foothill Freeway east
This mileage sign identifies the last two exits along Interstate 210 as well as the first exit along eastbound California 210: Sunflower Avenue; Junction California 57, Orange Freeway; and Lone Hill Avenue. Photo taken by AARoads (11/14/04).
Eastbound Interstate 210 reaches Exit 43, Sunflower Avenue. The next exit is Exit 45, Junction California 57/Orange Freeway south to Anaheim and Santa Ana. The section of California 57 between Interstate 10 and Interstate 210 used to be part of Interstate 210, but that changed once the California 210 freeway was opened between California 57 and Interstate 15. Once the section between Interstate 15 and Interstate 215 is completed in 2007, the entire route will become part of Interstate 210, including California 30 through San Bernardino and Redlands. Photo taken by AARoads (11/14/04).
The left four lanes plus high occupancy vehicle lane continue east on California 210, while the right lane exits onto southbound California 57. Note that Interstate 210 is no longer mentioned. Photos taken by AARoads (11/14/04) and Pete Sison (04/27/03).
The next three exits along eastbound according to this mileage sign are Junction California 57, Orange Freeway; Lone Hill Avenue; and San Dimas Avenue. Photo taken by AARoads (11/14/04).
California 210 and California 57 split here at this interchange. California 57 used to be signed as Interstate 210; those signed were removed and replaced with these reflective signs. Photo taken by AARoads (11/14/04) and Pete Sison (04/27/03).
Levente Jakab (07/15/07).
This is the first reassurance shield for California 210 after the onramp from North San Dimas Avenue (Exit 46), which is the first interchange east of California 57. Signs on the ramps from North San Dimas Avenue point to Interstate 210 west and California 210 east. Photo taken by AARoads (11/14/04).
Perspective from California 57/Orange Freeway north
Now traveling north on California 57/Orange Freeway, this is the first advance signage for the junction with California 210. The final three exits on California 57 north are: Exit 24B, Arrow Highway; Exit 25A, Auto Centre Drive; and Exits 25B-C, Junction California 210 east/Interstate 210 west. Photo taken by Andy Field and
Northbound California 57/Orange Freeway reaches Exit 24B, Arrow Highway in San Dimas. The next two exits are Exit 25A, Auto Centre Drive and Exit 25B, Junction California 210 east to San Bernardino. Note the greenout overlay on this sign for "California 210." Two possible shields rest underneath the green-out overlay: California 30 ... or Interstate 210. Photo taken by Andy Field and Levente Jakab (07/15/07).
The next exit on California 57/Orange Freeway north is Exit 25A, Auto Centre Drive. In the distance is Exits 25B-C, Junction California 210 east/Interstate 210 west. Photo taken by Andy Field and Levente Jakab (07/15/07).
A final California 57 north shield is posted on the Orange Freeway. The next exit along northbound is Exit 25A, Auto Centre Drive and Exits 25B-C, Junction California 210 east/Interstate 210 west. Photo taken by Andy Field and Levente Jakab (07/15/07).
Northbound California 57/Orange Freeway reaches Exit 25A, Auto Centre Drive. Photo taken by Andy Field and Levente Jakab (07/15/07).
Shortly thereafter, northbound California 57/Orange Freeway enters the city of Glendora, which serves as the state route's northern terminus. The final split between Interstate 210 west and California 210 east lies ahead. Photo taken by Andy Field and Levente Jakab (07/15/07).
Northbound California 57/Orange Freeway splits. The left three lanes follow Exit 25C to Interstate 210/Foothill Freeway west to Azusa, Duarte, Monrovia, Arcadia, Pasadena, La Cañada-Flintridge, Glendale, San Fernando, and Los Angeles. The right two lanes follow Exit 25B to California 210/Foothill Freeway east to San Bernardino via La Verne, Claremont, Upland, Rancho Cucamonga, Fontana, Rialto, and Muscoy. Photo taken by Andy Field and Levente Jakab (07/15/07).
Perspective from California 210/Foothill Freeway west
Traveling west on California 210/Foothill Freeway, this mileage sign after the Fruit Street interchange provides the distance to the next three exits: Exit 47, Junction California 66/Foothill Boulevard east; Exit 46, San Dimas Avenue; and Exit 45, Junction California 57/Orange Freeway south.

Westbound California 210/Foothill Freeway reaches Exit 47, Junction California 66/Foothill Boulevard east. The next interchange is Exit 46, San Dimas Avenue. Photo taken by Andy Field and Levente Jakab (07/15/07).
This mileage sign on westbound California 210/Foothill Freeway provides the distance to the next three exits: Exit 46, San Dimas Avenue; Exit 45, Junction California 57/Orange Freeway south; and Exit 44, Lone Hill Avenue. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
The first pull-through sign to say Interstate 210 west to Pasadena is posted between the Foothill Boulevard and San Dimas Avenue interchanges. The signage for California 57 was altered from its original configuration; it used to read "To Interstate 10, California 57, and California 71 south, use Interstate 210 east." The shields were rearranged on the button-copy, non-reflective sign rather than replaced in its entirety with a reflective sign. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
Westbound California 210/Foothill Freeway enters the city of San Dimas. The interchange between California 210, Interstate 210, and California 57 is mostly in Glendora, although the approach ramps are in San Dimas. Photo taken by Andy Field and Levente Jakab (07/15/07).
The next exit on westbound California 210/Foothill Freeway is Exit 46, San Dimas Avenue. Photo taken by Andy Field and Levente Jakab (07/15/07).
Westbound California 210/Foothill Freeway reaches Exit 46, San Dimas Avenue. The next exit is the connection to California 57/Orange Freeway south to Santa Ana, the seat of Orange County. Photo taken by Andy Field and Levente Jakab (07/15/07).
This mileage sign provides the distance to the next three exits on westbound California 210/Foothill Freeway: Exit 45, Junction California 57/Orange Freeway south; Exit 44, Lone Hill Avenue; and Exit 43, Sunflower Avenue. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
A final California 210 reassurance shield is posted prior to the California 57 interchange. The next reassurance shield is for Interstate 210 west. Photo taken Andy Field and Levente Jakab (07/15/07).
Westbound California 210 meets California 57/Orange Freeway (former Interstate 210) at Exit 45. Prior to the freeway renumbering here, this interchange served as the western terminus of California 30, and Interstate 210 traveled southeast from here to Pomona and west to Pasadena. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
Former Eastern Terminus - Interstate 10 - Pomona, California
Perspective from California 57/Orange Freeway south
Now traveling south on California 57/Orange Freeway, the first signage for the Kellogg Interchange (Junction Interstate 10 and California 57) appears on this mileage sign for upcoming exits. The Kellogg Interchange in Pomona used to serve as the eastern terminus for Interstate 210 until the Interstate was rerouted to end at the California 57/Orange Freeway interchange. Photo taken by Andy Field and Levente Jakab (07/15/07).
Southbound California 57/Orange Freeway reaches Exit 24A, Covina Boulevard. This porcelain-enamel overhead guide sign has been in place since this freeway was constructed as part of Interstate 210. Since the section of California 57 between Interstate 10 and Interstate 210 was built with chargeable Interstate funds, it is not clear if this stretch is still considered an Interstate highway based on original funding sources. Photo taken by Andy Field and Levente Jakab (07/15/07).
The next exit is Exit 22D, Via Verde and Raging Waters Drive. Photo taken by Andy Field and Levente Jakab (07/15/07).
The next three exits on southbound California 57/Orange Freeway are Exit 22D, Via Verde and Raging Waters Drive; Exit 22C, Junction California 71/Corona Freeway south; and Exits 22B-A, Junction Interstate 10/San Bernardino Freeway. Photo taken by Andy Field and Levente Jakab (07/15/07).
Southbound California 57/Orange Freeway reaches Exit 22D, Via Verde and Raging Waters Drive. The next exit is the connection to California 71/Corona Freeway south, followed by Junction Interstate 10. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
The right two lanes of California 57/Orange Freeway south will connect to Exit 22C, Junction California 71/Corona Freeway south to Pomona, Chino, Chino Hills, and Corona. The next exit is Exits 22B-A, Junction Interstate 10/San Bernardino Freeway. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
Continuing south, a second sign advises of the lane configuration for the junction with Exit 22C, Junction California 71/Corona Freeway south to Pomona, Chino, Chino Hills, and Corona and Exits 22B-A, Junction Interstate 10/San Bernardino Freeway. These signs were all button-copy, non-reflective signs until Interstate 210 signs were removed through this interchange between 2003 and 2006. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
Southbound California 57/Orange Freeway reaches Exit 22C, Junction California 71/Corona Freeway south to Pomona, Chino, Chino Hills, and Corona. Use the left three lanes to continue south on California 57. The next exit is Exits 22B-A, Junction Interstate 10/San Bernardino Freeway. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
Shortly thereafter, southbound California 57/Orange Freeway reaches Exits 22B-A, Junction Interstate 10/San Bernardino Freeway. The Kellogg Interchange is a symmetrical stack interchange, and for some reason Caltrans decided to give exit numbers to Interstate 10 east and west even though they are both served by a single transition ramp. This offramp marked the former eastern terminus of Interstate 210. Photos taken by Andy Field and Levente Jakab (07/15/07) and Pete Sison (09/27/02).
A bridge sign is the only evidence that the Kellogg Interchange in Pomona used to serve as the eastern terminus of Interstate 210: the sign reads "Route 57, 210/10 Separation." Photo taken by Andy Field and Levente Jakab (07/15/07).
Perspective from California 57/Orange Freeway north
Now traveling north on California 57/Orange Freeway, this is the first advance signage for the junction with Interstate 10 (Exit 21). Previously, the pull-through sign for California 57 was signed as Interstate 210 west Pasadena. That signage changed when California 210 was legislatively created to extend east to Redlands. Photos taken by Andy Field (07/04/07) and Pete Sison (09/27/02).
After traffic from Temple Avenue (Exit 20) merges onto northbound California 57/Orange Freeway, the right two lanes become exit only for Interstate 10 west to Los Angeles and east to San Bernardino. The left three lanes will proceed north through the Kellogg Interchange to provide a connection to what is now Interstate 210 and California 210. Photos taken by Andy Field (07/04/07) and Pete Sison (09/27/02).
This mileage sign provides the distance to the next three exits on northbound California 57/Orange Freeway. Previously, this sign showed the first three exits for former Interstate 210. Now these three exits use California 57 exit numbers: Exit 21, Junction Interstate 10/San Bernardino Freeway; Exit 22, Via Verde/Raging Waters Drive; and Exit 24A, Covina Boulevard. Photo taken by Andy Field (07/04/07).
The right two lanes exit for Exit 21, Junction Interstate 10/San Bernardino Freeway at the symmetrical stack Kellogg Interchange. California 57 continues north; the pull through sign used to read "Interstate 210 Freeway West Pasadena." Photo taken by Andy Field (07/04/07).
The only remaining signage that indicates that Interstate 210 used to be routed through the Kellogg Interchange is this bridge log identification sign, which refers to this interchange as the Route 57-210-10 separation. It is posted on northbound California 57/Orange Freeway after the Interstate 10 exit. Photo taken by Andy Field (07/04/07).
The next exit on northbound California 57/Orange Freeway is Exit 22, Via Verde/Raging Waters Drive in San Dimas. Traffic from California 71/Corona Freeway merges onto northbound California 57 from the right. Photo taken by Andy Field (07/04/07).
This mileage sign provides the distance to the next three exits on northbound California 57/Orange Freeway: Exit 22, Via Verde/Raging Waters Drive; Exit 24A, Covina Boulevard; and Exit 24B, Arrow Highway. Photo taken by Andy Field (07/04/07).
Perspective from California 71/Chino Valley Freeway north
California 71 northbound at the eastern Interstate 10 offramp. California 71 continues northbound to Interstate 10 westbound and a transition onto California 57, which was formerly signed as Interstate 210 west (compare 2002 and 2007 photos). Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Andy Field/Levente Jakab (07/15/07).
The next exit on northbound California 71/Chino Valley Freeway is the connection to Interstate 10/San Bernardino Freeway west to Los Angeles. Photo taken by Andy Field/Levente Jakab (07/15/07).
California 71 is changing dramatically as various upgrades convert a former four-lane, at-grade expressway into a multi-lane freeway. Even the section of California 71 through Pomona, which is currently regulated by a series of traffic signals between Interstate 10 and California 60, it planned for possible conversion to freeway, but it is not programmed for construction until the late 2000s/early 2010s. The other section of California 71 recently upgraded is the interchange with California 91 in Riverside County; construction was complete by 2005. Once the entire freeway corridor is complete, California 71 will provide a freeway link from California 91 north to California 57/Interstate 10. Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Andy Field/Levente Jakab (07/15/07).
Use the left two lanes to follow California 71 north to California 57. Compare the difference in signage between 2002 and 2007. Note that Interstate 210 rather than California 57 was signed here in the earlier photo. Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Andy Field/Levente Jakab (07/15/07).
Continuing north, the left two lanes connect California 71 to California 57 (Former Interstate 210), and the right lane connects to Interstate 10/San Bernardino Freeway west to Los Angeles. Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Andy Field/Levente Jakab (07/15/07).
Transition from California 71 northbound onto California 57/Orange Freeway north (former Interstate 210 west). This roadway makes up the top level of the Kellogg stack interchange between Interstate 10 and California 57/71. Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Andy Field/Levente Jakab (07/15/07).
Perspective from Interstate 10/San Bernardino Freeway east
Now traveling east on Interstate 10/San Bernardino Freeway, this mileage sign is the first to advise of the pending junction with California 57/Orange Freeway, which is the former route of Interstate 210. Photo taken by Alex Nitzman (03/25/05).
Eastbound Interstate 10/San Bernardino Freeway reaches Exit 40, Via Verde. The next exit is Exit 41, Kellogg Drive to California State Polytechnic (Cal Poly) University. Immediately thereafter is Exit 42A, Junction California 57 south to Santa Ana and north to Glendora. Photo taken by Alex Nitzman (03/25/05).
The next three exits on eastbound Interstate 10/San Bernardino Freeway are Exit 41, Kellogg Drive to California State Polytechnic (Cal Poly) University; Exit 42A, Junction California 57/Orange Freeway south to Santa Ana and north to Glendora; and Exit 42B, Junction California 71/Corona Freeway south to Pomona and Chino. Exits 42A-B form the massive Kellogg Interchange, a symmetrical stack between Interstate 10 and California 57 with connectors to California 71. Photo taken by Alex Nitzman (03/25/05).
Prior to Exit 41, Kellogg Drive are these signs for Exit 42A, Junction California 57/Orange Freeway and Exit 42B, Junction California 71/Corona Freeway. The California 71 sign is an original porcelain-enamel, button-copy sign, but the California 57 sign is a reflective replacement that includes the exit number. It used to show Interstate 210 west and California 57 south. Photo taken by Alex Nitzman (03/25/05).
Eastbound Interstate 10/San Bernardino Freeway reaches Exit 41, Kellogg Drive to California State Polytechnic (Cal Poly) University. The next exit is the ramp to Exit 42A, Junction California 57 south to Santa Ana and north to Glendora and Interstate 210. Photo taken by Alex Nitzman (03/25/05).
Interstate 10 eastbound at the ramp for Interstate 210 westbound and California 57 south. California 57 heads south towards Anaheim while Interstate 210 heads north before turning west at Glendora. The Kellogg interchange is visible in the background. Photos taken by Andy Field/Kevin Trinkle (05/02/02) and Alex Nitzman (03/25/05).
Interstate 10 east next reaches the ramp to Exit 42B, Junction California 71/Corona Freeway south to Pomona, Chino, and Corona. The four-level stack Kellogg Interchange sits on top of Interstate 10, which forms the lowest level. This intricate structure of the symmetrical stack interchange is best seen from Interstate 10, but its provides quite an impressive view on top along California 57. Photos taken by Alex Nitzman (03/25/05).
Perspective from Interstate 10/San Bernardino Freeway west
Now traveling west on Interstate 10/San Bernardino Freeway, this mileage sign is the first appearance of California 57 signage. The next exit is Exit 44, Dudley Street and Fairplex Drive, followed by Exit 42, Junction California 57/Orange Freeway. Photo taken by Andy Field (06/17/06).
Use Exit 44, Dudley Street and Fairplex Drive to Pomona and to Business Loop I-10/Holt Avenue (former U.S. 70-99) through downtown. Interstate 10 widens into a dual freeway arrangement, with collector-distributor lanes connecting to Dudley Street and Fairplex Drive. Photo taken by Andy Field (06/17/06).
The collector-distributor lanes for Exit 44, Dudley Street and Fairplex Drive split off of westbound Interstate 10/San Bernardino Freeway. The next exit is Exit 42, Junction California 57/Orange Freeway. There is no access from westbound Interstate 10 to southbound California 71/Corona Freeway. Photo taken by Andy Field (06/17/06).
Another upcoming exits sign is posted on westbound Interstate 10/San Bernardino Freeway. The next three exits are Exit 42, Junction California 57/Orange Freeway; Exit 41, Kellogg Drive/California State Polytechnic University (Cal Poly Univ), and Exit 40, Via Verde. Photo taken by Andy Field (06/17/06).
The right two lanes on westbound Interstate 10/San Bernardino Freeway provide the connection to California 57. The new signage indicates that California 57 north leads to Interstate 210. The left four lanes (five lanes counting the carpool lane) continue straight ahead toward Los Angeles. Photo taken by Andy Field (06/17/06).
Westbound Interstate 10/San Bernardino Freeway reaches Exit 42, Junction California 57/Orange Freeway. Upon departing the freeway, the left lane will connect to California 57/Orange Freeway south, while the right lane connects to California 57/Orange Freeway north to Interstate 210 and California 210. This is the former eastern terminus of Interstate 210. Photo taken by Andy Field (06/17/06).
The right lane of westbound Interstate 10/San Bernardino Freeway becomes exit only for Exit 41, Kellogg Drive/California State Polytechnic University (Cal Poly Univ). The bridge carrying California 71/Corona Freeway over Interstate 10 can be seen high above Interstate 10. Photo taken by Andy Field (06/17/06).
Passing through the massive Kellogg Interchange, Interstate 10/San Bernardino Freeway serves as the bottom level and thus provides the best view of the interchange. Three separate freeways converge here, and high-speed movements are required in most directions. The next exit is Exit 41, Kellogg Drive/Cal Poly University. Photo taken by Andy Field (06/17/06).
Future Eastern Terminus - Interstate 10 - Redlands, California
