Interstate Business Route 10

Westbound Business Loop I-10 follows Motel Drive through Lordsburg. It is cosigned with portions of U.S. 70 and New Mexico 90 along its route through town. Photo taken 06/15/08.

Transcontinental Interstate 10 has approximately 12 active business loops as well as several decommissioned business routes. Most of its companion U.S. routes west of San Antonio have been decommissioned, and most of its remaining business routes are old alignments of those U.S. routes.

Location Status Description
Pomona, Montclair, and Ontario Decommissioned with Remnant Shields This was formerly Business U.S. 70-99 and was signed as Business Loop I-10 in the 1960s along Holt Boulevard. The loop begins at the Kellogg Interchange (Exit 42B to southbound California 71, then east on Holt Avenue at Exit 14 from California 71) and is supposed to extend east to near Ontario International Airport. Shields still remain along this route, which follows Holt Boulevard between California 71 and just east of the Ontario International Airport, even though signs to this route from the mainline freeway have disappeared. Ali Pezeshkpour wrote on May 1, 2001, "The business shields are only found in Pomona, and even though I have desperately tried to find some sign that would point to a business route, I have found none on California 71 or Interstate 10. The interchanges with these freeways are not optimal, because first of all, only westbound Interstate 10 can access Holt Boulevard, and only eastbound Holt Boulevard can access eastbound Interstate 10, which allows for minimum signage even for Holt Boulevard. [At] the California 71 interchange no signs are here for any loop either. The loop shields were continuous until California 71. The reason we suspect the shields are only in Pomona is because Pomona is Los Angeles County and Ontario and beyond is in San Bernardino County."
Fontana and Colton Decommissioned with Remnant Shields This business route begins east of Interstate 15 and follows Valley Boulevard (former U.S. 70-99) through Colton between Exit 59 (Etiwanda Avenue/Valley Boulevard/Commerce Drive) and Exit 71 (Mount Vernon Avenue). Cameron Kaiser has photos from 2006 that verify that the loop is signed at least once on Valley Boulevard, but this business loop is not listed in the 1991 state signing log.
Indio Decommissioned with Remnant Shields This business route used to follow Indio Boulevard along former U.S. 60-70-99, beginning at Exit 139 and returning to Interstate 10 at Exit 146 via Dillon Road. Between 2006 and 2008, the green business loop shields were removed, and now all that remains are Historic U.S. 99 shields. This business route is a well-preserved section of old U.S. 99 through Indio as it parallels a railroad. The western part of the route is maintained by the city, the middle segment is controlled by the state, and the eastern section is maintained by the city of Coachella. At its intersection with California 111 just east of downtown (intersection of Indio Boulevard, Golf Center Parkway, and Avenue 46) is the northern terminus of California 86. California 86-111 then used to run concurrently south along with Business Loop I-10. The business route left Indio, then turns northeast at the Coachella city limits onto Dillon Road. The business loop follows Dillon Road past the California 86S expressway interchange, then rejoins Interstate 10 at Exit 146. According to the California State Highway System Signing Log (October 1991), Business Loop I-10 in Indio runs from "Interstate 10 and Indio overcrossing near Indio via Indio Boulevard and State Route 86 to Interstate 10 and Dillon Road."
Blythe Active This business loop is not listed in the 1991 state signing log, but it is well-signed. The business loop begins at Exit 236, Junction California 78/Neighbors Boulevard. From Exit 236, Business Loop I-10 follows Neighbors Boulevard north briefly, then turns east onto Hobsonway (Old U.S. 60-70), then follows Hobsonway east into downtown Blythe. The business route returns to Interstate 10 near the Colorado River at the Riviera Drive interchange (Exit 243). To rejoin Interstate 10, the business loop follows Hobsonway to Queshan Park, then turns due south to pass under Interstate 10, and then it turns west briefly to the onramp back onto Interstate 10.
Quartzsite Active This business route serves Quartzsite via Main Street (Old U.S. 60-70) between Exits 17-19 via old U.S. 60-70. It provides the direct connection to U.S. 95 and Arizona 95. Signage from mainline Interstate 10 only shows Business 10 on the blue motorist services sign.
Phoenix Decommissioned Business Loop I-10 through Phoenix used to follow Van Buren Street and the Arizona 143 Freeway; it was in place while the parent route Interstate 10/Papago Freeway was under construction. By the early 1990s, it was decommissioned, perhaps after the Interstate 10 freeway was opened to traffic on August 10, 1990. Alan Hamilton writes, "I don't have any pictures, though I have a picture of where a BL-10 shield was peeled off Interstate 17 exit 200B at (see I-17 Exit 200B). (Prior to its decommissioning, Business Loop I-10) was signed at the southbound Van Buren exit on I-17, on the eastbound exit at 27th Ave on I-10, and (with various) reassurance markers through Phoenix. There weren't any markers on the mainline at the east end on Interstate 10 at 44th Street. I'm not sure when Business Loop I-10 was established, or what relation it had to the construction of the Interstate 10 freeway through central Phoenix." The Rand McNally Road Atlas typically showed the business loop as active on its Phoenix maps well into the 1990s, but it was finally removed in the 2000s editions.
Casa Grande Decommissioned Former Business Loop I-10 used to follow Arizona 387 and Arizona 287 between Interstate 10 Exits 185 and 194 through Casa Grande. Former Arizona 84 (Jimmie Kerr Boulevard) is not part of this business route. This loop was eliminated in the 2000s when sections of the business loop was transferred to local maintenance and removed from the state highway system. Typically, off-Interstate business loops and spurs in Arizona are within the state highway system. Once the business route was removed from the state system, the signed designation was eliminated along with it.
Tucson #1 Decommissioned Former Business Loop I-10 through downtown Tucson was decommissioned from the state highway system at some point in the late 1990s, and as a result, the business loop no longer exists. For a time prior to its elimination, the shield assemblies that used to include Business Loop I-10 also had space for the U.S. 89 shield, which was decommissioned south of Flagstaff in 1992. From northwest to southeast, this portion of Business Loop I-10 (between Exits 255 and 261) used to follow Arizona 77/West Miracle Mile, Oracle Road (old U.S. 80-89), Speedway Boulevard, Stone Avenue, the South Stone Avenue/Sixth Avenue couplet, and Sixth Avenue. At Interstate 10 Exit 261 (South Tucson), former Business Loop I-10 ended. From this point, former Business Loop I-19 (old U.S. 89) south began. Tucson #2 Business Loop I-10/Tucson-Benson Highway used to begin only a mile southeast of here, but it too is no longer within the state highway system and has also been decommissioned.
Tucson #2 Decommissioned Between Exits 262 and 267, this instance of Business Loop I-10 followed old U.S. 80 and the Tucson-Benson Highway in eastern Tucson. This route was not signed as a business loop yet was state maintained and logged as an official business loop until 2007, at which time it was no longer part of the state highway system and removed as an official business loop. The Rand McNally Road Atlas showed this route as an actively signed business loop throughout the 1990s and into the early 2000s before its designation was removed from the map.
Benson (Loop) Active Old U.S. 80, which was overlaid by Interstate 10 between Tucson and Benson, curved south to Douglas at Benson. Interstate 10, meanwhile, replaced old Arizona 86 between Benson and the New Mexico State Line. The business loop in Benson was old U.S. 80 and old Arizona 86 between Exit 303 and Exit 306 via Fourth Street.
Benson (Spur) Unsigned and Decommissioned According to the state highway log, there was a Business Spur I-10 from Interstate 10 at Exit 304 (Ocotillo Avenue in Benson) to Business Loop I-10. The interchange was built in 1987. The business spur is not signed on the mainline, and there are no business spur signs present along Ocotillo (per our visit in May 2003 and again in June 2008). Thanks to Alan Hamilton for assistance locating this route. The Arizona State Highway System Log, prepared and updated by the Arizona Department of Transportation, provides the latest updates on the status of all Arizona state highways, including business loops and spurs. We could not find this route in the 2009 edition (listed simply as "Ocotillo Avenue"), but it does appear in the 1998 edition (as "SS010," which appears to mean "state spur" from Interstate 10).
Willcox Active Business Loop I-10 in Willcox follows Haskell Avenue (old Arizona 86 and old U.S. 666) between Interstate 10 Exits 336 and 344. U.S. 191, which replaced U.S. 666, follows the freeway rather than the business loop through town.
Bowie Active Business Loop I-10 in Bowie follows Sixth Street (old Arizona 86) between Interstate 10 Exits 362 and 366.
San Simon Active Business Loop I-10 in San Simon follows Sixth Street (old Arizona 86) between Interstate 10 Exits 378 and 382. Interestingly, both Bowie and San Simon's main east-west streets are labeled as Business Loop I-10/Sixth Street.
Lordsburg Active Business Loop I-10 in Lordsburg follows Old U.S. 80 between Interstate 10 Exit 26B (Lordsburg West/Motel Drive) and Exit 24 (Lordsburg East/Motel Drive). Motel Drive follows the railroad closely as it passes through downtown Lordsburg.
Deming Active Business Loop I-10 in Lordsburg follows Old U.S. 70-80 between Interstate 10 Exit 81 (Deming West/Pine Street) and Exit 85 (Deming East/Pine Street) at a trumpet interchange. U.S. 180 overlaps the eastern half of the route (east of Gold Avenue).
Las Cruces Decommissioned with Remnant Signs This loop used to serve Las Cruces. It is not signed from the mainline of Interstate 10. However, there are remnant shields along the route (at least one was spotted in June 2008). According to Patrick Valdez and Dan Moraseski, the Las Cruces business loop starts at Exit 135, which is U.S. 70/Picacho Avenue. The loop follows U.S. 70 east to Main Street, turns right (southeast) on Main Street through downtown, merges with Valley Drive, then reconnects with the freeway at the Valley Drive exit (Exit 142/New Mexico 188). According to Patrick Valdez, the business loop is well signed from the Valley Drive intersection to the intersection with Alameda/El Paseo Drive in both directions, but the signage disappears thereafter. As of October 2003, there are no business loop shields on Picacho Avenue, with the sole exception of one trailblazer shield along eastbound that directs business loop traffic to turn right onto Main Street. These shields may have been removed due to the construction along parts of Picacho Avenue.

Sierra Blanca Active Entering Texas and now east of the El Paso metropolitan area, Business Loop I-10C travels for 2.7 miles in Hudspeth County through the county seat of Sierra Blanca along old U.S. 80 (El Paso Street between Interstate 10 Exits 105 and 108). Sierra Blanca is notable for being close to a decommissioned sludge dump that used to accept tons of sewage from New York City until 2001.
Van Horn Active Business Loop I-10D runs for 2.9 miles in Culberson County via old U.S. 80 by following Broadway Street between Exits 138 and 140B.
See Texas @ AARoads - Business Loop I-10 - Van Horn for photos of the route.
Balmorhea Active Business Loop I-10F runs for 4.6 miles in Reeves County via Old U.S. 290. This route begins at Interstate 10 Exit 206, travels southeast along Texas Farm to Market 2903, then turns northeast along Texas 17 to return to Interstate 10 at Exit 209.
Fort Stockton Active Business Loop I-10G runs for 4.4 miles in Pecos County between Exits 256 and 261 via Old U.S. 290/Dickinson Boulevard through Fort Stockton. This is the last business loop for Interstate 10 eastbound.
Ozona Not a Business Route The former U.S. 290 through Ozona is not an official business loop; it is signed as Texas Loop 466 between Exit 363 and Exit 368 via Sheffield Road and Eleventh Street.
Sonora Not a Business Route The former U.S. 290 through Sonora is not an official business loop; the business loop route would have begun at Exit 399, travel southeast along Texas Loop 467/Crockett Avenue, U.S. 277 and Texas Loop 467/Crockett Avenue, and Texas Loop 467/Crockett Avenue again. The presumptive loop would return to Interstate 10 at Exit 404.
Junction Not a Business Route The former U.S. 290 through Junction is not an official business loop; it is signed as Texas Loop 481. The presumptive business loop begins at Interstate 10 Exit 456, follows U.S. 377/Main Street south into downtown, and continues southeast along Texas Loop 481/Main Street across Lake Junction and rejoins Interstate 10 and U.S. 83 at Exit 460.
Kerrville, Comfort Not a Business Route Kerrville does not have nor has been considered for a business loop. A proposed business loop would follow Texas 27 between Exits 488 and 524 through downtown Kerrville, Center Point, and Comfort. An instance of Business U.S. 87 exists between Exits 523 and 524 via Comfort, Texas.
Boerne Not a Business Route Interstate 10 and U.S. 87 are multiplexed through here, and the former U.S. 87 route through town via Main Street is signed as Business U.S. 87 between Exits 537 and 542.
San Antonio Not a Business Route A former instance of Business U.S. 87 extends from Exit 560A and follows Texas Loop 345/Fredericksburg Road. The loop route returns to Interstate 10 at Exit 568. This is no longer signed as Business U.S. 87 and is not signed as an Interstate business loop.
Columbus Not a Business Route Because U.S. 90 is multiplexed with I-10 on and off between San Antonio and Houston, most towns along this corridor carry U.S. 90 where a Business Loop would otherwise exist. A potential loop from Interstate 10 through Columbus would connect Exit 689 to Exit 698 via Walnut Street.
Sealy Not a Business Route Because U.S. 90 is multiplexed with I-10 on and off between San Antonio and Houston, most towns along this corridor carry U.S. 90 where a Business Loop would otherwise exist. This loop, serving Sealy, connects Intestate 10 Exit 718 and 721.
Beaumont Not a Business Loop This is signed as U.S. 90 between Exits 851 and 855. Stephen Taylor writes, "U.S. 90 simply continues to follow its old route through Beaumont and is not a loop or Business Route of any sort. Although it is co-signed with I-10 coming out of Orange County to the city limits on the east, it veers off and follows its original route through town and goes back to 10 on the west side of town and goes under 10, not rejoining it but going due west on its original route toward Houston."
Orange Not a Business Loop U.S. 90 exits Interstate 10 just past Mile Marker 873 (Exit 873B), and it follows the old alignment of Business U.S. 90 through Pinehurst, and then through Orange itself before turning due north and rejoining the Interstate at Exit 878. According to Stephen Taylor, both eastbound and westbound exits are plainly marked for Business U.S. 90.

The first westbound shield for Business Loop I-10 in Pomona, California. Most instances of business loops from Interstate 10 have been decommissioned or are no longer signed. They typically represent the old alignment of the parallel U.S. highway, typically U.S. 60, U.S. 70, and/or U.S. 99. Photo taken 07/15/07.
Business Loop I-10 remains signed along Valley Drive in Las Cruces, New Mexico. However, signs for this business route are no longer posted along the Interstate 10 mainline. This shield is posted along New Mexico 188/Valley Drive northbound after Interstate 10 Exit 142 in Las Cruces. The business route is assumed decommissioned due to the lack of consistent signage along this route. Photo taken 04/28/12.
Interstate 10 eastbound at the Exit 138 off-ramp to Business Loop I-10 at Van Horn, Texas. The Interstate 10 business loops in west Texas follow old alignments of U.S. 80. Photo taken 01/14/06.
