Interstate Business Route 10

Interstate 10 has approximately 13 active and unsigned business loops and a few decommissioned loops as well (including the one that often shows up on the Phoenix downtown map).

	Location Status Description CALIFORNIA Pomona, Montclair, and Ontario, California Decom. /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 Decom. /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 Decom. /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, then follows Hobsonway east into downtown Blythe. The business route retuns 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. ARIZONA Quartzsite Active This business route serves Quartzsite 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 Decom. Business Loop I-10 through Phoenix used to follow Van Buren St. and the State Route 143 Freeway. By the late 1980s, it was decommissioned, perhaps after the Interstate 10 freeway was constructed. 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." Casa Grande Active Thanks to Alan Hamilton for locating this one. Business Loop I-10 follows 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. There is no Interstate 8 business connection at Casa Grande. Tucson Decom. Business Loop I-10 has been decommissioned from the state highway system, and it is not marked from Exit 255 mainline signs. Shields for Business Loop I-10 were removed in the late 1990s. For a time, the shield assemblies that used to include Business Loop I-10 also had space for the U.S. 89 shield, which has been decommissioned for several years now. This portion of Business Loop I-10 (between Exits 255 and 261) used to follow West Miracle Mile, North Miracle Mile (old U.S. 80-89), Fourth Avenue, the South Stone Avenue/Sixth Avenue couplet, and Sixth Avenue. At Junction Interstate 10 Exit 261 (South Tucson), former Business Loop I-10 ends. From this point, Business Loop I-19 (old U.S. 89) south begins. An unsigned Business Loop I-10 for Tucson begins a mile southeast of here, and it is within the state highway system. Tucson Decom. Between Exits 262 and 267, this instance of Business Loop I-10 followed old U.S. 80 and the Tucson-Benson Hwy in eastern Tucson. This route was not signed as a business loop, and by 2007 it was no longer part of the state highway system. 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 replaced old Arizona State Route 86 between Benson and the New Mexico State Line. The business loop in Benson was old U.S. 80 and old Arizona 86 between Exits 303-306. (Thanks to Alan Hamilton for this information.) Benson (Spur) Unsigned According to the state highway log, there is a Business Spur I-10 from Interstate 10 at Exit 304 (Ocotillo Street in Benson) to Business Loop I-10. It's not signed on the mainline, and there are no business spur signs present along Ocotillo (per visit in May 2003). We visited this business spur in June 2008 and can verify that no shields are present along this route. Thanks to Alan Hamilton for the route log information. Willcox Active Old Arizona 86 (and old U.S. 666) between Exits 336 and 344. U.S. 191 follows the freeway rather than the business loop through town. Bowie Active Old Arizona 86 between Exits 362 and 366. San Simon Active Old Arizona 86 between Exits 378 and 382. NEW MEXICO Lordsburg Active Business Loop I-10 is clearly marked on the DeLorme's map of New Mexico along Old U.S. 80. Deming Active This business loop appears on the DeLorme's map of New Mexico. Las Cruces Decom. /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 Pichacho 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. TEXAS Sierra Blanca Active Business Loop I-10C goes for 2.7 miles in Hudspeth County through Sierra Blanca. This is old U.S. 80. I saw this business loop marked on a highway sign off I-10 in the background of a reporter during a television news magazine report. Funny how I can't remember what the topic was. Van Horn Active Business Loop I-10D runs for 2.9 miles in Culberson County via old U.S. 80. Balmorhea Active Business Loop I-10F runs for 4.6 miles in Reeves County via Old U.S. 290. Fort Stockton Active Business Loop I-10G runs for 4.4 miles in Pecos County via Old U.S. 290 through Fort Stockton. This is the last business loop for Interstate 10 eastbound. Ozona Not a Business Route The former U.S. 290 route that seems perfect for a Business Loop is officially Texas Loop 466. Sonora Not a Business Route The former U.S. 290 route that seems perfect for a Business Loop is officially Texas Loop 481. Junction Not a Business Route The former U.S. 290 route that seems perfect for a Business Loop is officially Texas Loop 467. Kerrville Not a Business Route Kerrville does not have nor has been considered for a Business Loop. A proposed business loop would follow a combination of Texas 27, Texas Farm-to-Market Route 783, and Texas 16. Boerne Not a Business Route Interstate 10 and U.S. 87 are multiplexed here, and the former U.S. 87 route through town is signed as Business U.S. 87. Columbus Not a Business Route Because U.S. 90 is muliplexed 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. Sealy Not a Business Route Because U.S. 90 is muliplexed 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. 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.

Thanks to Alan Sims for providing needed information on several potential (but non-existent) Business Routes in Mid-Texas.
