Interstate 40
Highway system

Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former U.S. route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.

Along Interstate 40 (I-40), business routes are found in the five westernmost states through which I-40 passes, California, Arizona, New Mexico, Texas, and Oklahoma, as well as North Carolina. The Interstate has no business routes along its passage through Arkansas nor Tennessee.

Some states regard Interstate business routes as fully integrated within their state highway system while other states consider them to be either local roads to be maintained by county or municipal authorities or a hybrid of state and local control.

Although the public may differentiate between different business routes by the number of the parent route and the location of the route, there is no uniform naming convention. Each state highway department internally uses its own designations to identify segments within its jurisdiction.

From central Oklahoma westward, the business routes often follow the historic alignment of the former U.S. Route 66 (US 66).

California

Interstate business routes in California are assigned by the California Department of Transportation (Caltrans), but are not maintained by Caltrans unless they overlay other routes of the state highway system. Local authorities may request route assignment from the Caltrans Transportation System Information Program, and all requests require approval of the executive committee of the American Association of State Highway and Transportation Officials (AASHTO).

Needles

Interstate 40 Business
Location Needles
Length3.4 mi [2] (5.5 km)

The business loop of Interstate 40 through Needles in San Bernardino County begins at exit 141 of I-40/ US 95 northwest of town. The unsigned highway follows Broadway Avenue to the southeast to Needles Highway, then eastward through an underpass of I-40 into the town center. At N Street, the loop turns southward into the southern part of town where it reconnects with Broadway Ave. The route then continues southeastward to I-40 exit 144 where it terminates and US 95 continues southward along Broadway. The route largely follows the former route of US 66 through town except where the historic highway's path has since been disrupted by the construction of I-40. [2]

Major intersections

The entire route is in Needles, San Bernardino County.

Arizona

The business loops within Arizona are maintained by the Arizona Department of Transportation (ADOT) and by municipal authorities. Interstate 40 has five business loops within the state located in Seligman, Ash Fork, Flagstaff, Joseph City, and Holbrook and formerly had loops in Kingman, Flagstaff, and Winslow. ADOT identifies Interstate business loops as State Business Routes followed by the number of the parent Interstate. Individual loops along an Interstate are designated by adding parenthetical numbers that increase eastward and northward. Gaps in numbering represent removal of former routes or potential expansion.

The Adrian business loop of Interstate 40 begins at I-40 at exit 22 and runs along Former route 66 to exit 23, the latter of which also includes the norther terminus of TX 214.

Route description

Bus. I-40 B begins and ends at on-and-off ramps leading to and from two-way frontage roads along I-40, which in the case of the one on the northbound side, a genuine former section of Route 66. Eastbound BL-40 immediately turns north on Oldham County Road 22, which runs across an overpass above I-40 before terminating at Historic US 66, then turns right, where it encounters the official Midway Point of historic US 66, as well as a café and motel focused on this theme. East of there at the intersection with Grand Avenue, the post office is diagonally across from a campground, and beyond that point the road runs past some silos. When the route intersects the westbound off-ramp for Exit 22, which is the official westbound beginning of BL-40, eastbound BL 40 runs towards the northern terminus of TX 214, then turns south overlapping that route until it runs above I-40 again, before turning east on the frontage road until finally leaving at the on-ramp ending at I-40 itself.

Vega

Business Interstate 40-C
Location Vega
Length3.395 mi [20] (5.464 km)
Existed1990–present [20]

The Vega business loop of Interstate 40 runs along Former route 66 between two modified trumpet interchanges at exits 35 and 37. It is officially designated as Business Interstate 40-C by the Texas Department of Transportation.

Route description

Bus. I-40 C begins and ends at on-and-off ramps leading to and from two-way frontage roads along I-40, which in the case of the one on the northbound side, a genuine former section of Route 66. Eastbound BL-40 immediately turns southeast, away from the former Choctaw, Oklahoma and Gulf Railroad line, which was acquired and later abandoned by the Rock Island Railroad. [21] The surrounding landscape is completely barren until the road encounters a hotel. From 14th to 13th Streets, the road curves from southeast to straight east. The sole main intersection along the route is U.S. Route 385 (South Main Street), which contains intersection beacons. Though all of BL-40 is named Route 66, as well as Vega Boulevard, an older segment of the iconic route turned north in an overlap with US 385, and turned west onto West Main Street ending just east of where the intersection with the eastbound exit 35 ramps are. Between 7th and 6th Streets, BL 40 passes a Texas DOT construction and maintenance facility, and then curves southeast again east of Third Street to follow along the south side of the former Choctaw Route. After the intersection with First Street, the surroundings become barren once again, with the exception of one ranch on the south side. BL-40 C ends at Exit 37 on I-40, and the former segment of US 66 along the north side continues as one of the two I-40 frontage roads.

Amarillo

Business Interstate 40-D
Location Amarillo
Length14.125 mi [22] [nb 1] (22.732 km)
Existed1990–present [22]

The Amarillo business loop of Interstate 40 begins at I-40 exit 62A just west of Amarillo. The highway was formerly a business route for Route 66, being that highway's only bannered route in Texas. Bus. I-40 D is known locally as Amarillo Boulevard and is the longest bannered route of Interstate 40.

Route description

Bus. I-40 D begins at Interstate 40 exit 62A just west of Amarillo near Cadillac Ranch. The highway runs east through a low developed area before entering the Amarillo city limits just before an intersection with Loop 335 (Soncy Road). Bus. I-40 D turns northeast at an interchange with Coulter Street/Wolffin Avenue before briefly running north at an interchange with SW 9th Avenue/Bell Street (near the main campus of Amarillo College). The highway starts turning northeast at Tascosa Road/Gem Lake Road before running straight east at the N. Western Street interchange. After this interchange, Bus. I-40 D begins to travel through a heavily developed area of the city before meeting U.S. Route 60/ U.S. Route 87/ U.S. Route 287 just north of downtown and begins an overlap with U.S. Route 60. The two highways continue to travel through a heavily developed area of the city, with the development becoming more sparse after the State Highway 136 intersection. Bus. I-40 D becomes a divided highway after an interchange with Loop 335 (Lakeside Drive) and runs along the northern border of Rick Husband Amarillo International Airport. Just after leaving the Amarillo city limits, U.S. Route 60 leaves the highway and Bus. I-40 D starts to run southeast. Bus. I-40 D meets its eastern terminus at I-40 exit 85.

Groom

Business Interstate 40-F
Location Groom
Length3.533 mi [24] (5.686 km)
Existed1990–present [24]

The Groom business loop of Interstate 40 begins at I-40 at exit 110 and runs along Former route 66 to exit 114. Officially designated as Business Interstate 40-F by the Texas Department of Transportation, it is one of the few business routes to run along the south side of I-40 in Texas, rather than the north side.

Route description

Business Interstate 40-F begins at the off-ramp for Exit 110 leading to the I-40 frontage road along the eastbound lanes, which suddenly becomes a divided highway named "Route 66." The first intersection is a connecting road to the parts of the interchange with the eastbound on-ramp, as well as the frontage roads along the westbound lanes, leading to the western terminus of the business loop. Shortly after this is the barely paved Carson County Road BB. The divided highway ends just west of TX FM 295 and Carson County Road CC (Western Avenue), and gains the additional name of "Front Street." The route runs along the edge of town as a four-lane undivided highway with the south side lined with numerous massive grain silos along the abandoned Chicago, Rock Island and Gulf Railway line until the intersection with TX FM 2300 (Eastern Avenue), and after passing by a TxDOT maintenance facility, the road become a divided highway once again. Little else exists along this segment. The last intersection is another connecting road to the eastbound off-ramp of Exit 114, the frontage roads along the westbound lanes leading to the western beginning of the business loop, and an unorthodox roadside attraction known as the Leaning Tower of Texas. Business Interstate Route 40-F ends at the on ramp to eastbound I-40, as does the divided former US 66, which is converted back into the frontage road along the eastbound lanes of I-40.

McLean

Business Interstate 40-H

Length3.796 mi [25] (6.109 km)
Existed1990–present [25]

The McLean business loop of Interstate 40 runs from exit 141 to 143. It begins at I-40 at an eastbound flyover interchange and runs northeast along Former route 66. Before the intersection with 26th 1/2 Road, it curves to the southeast. After the intersection with Texas Highway 273, it splits into a one way pair with eastbound BL-40 H continuing along Railroad Street, and westbound BL-40 H moving onto First Street, one block to the north. This one-way pair comes to an end just at the intersection with a connecting road that brings Eastbound BL-40-H traffic under I-40 and then loops back from the south I-40 frontage road to end at I-40.

Shamrock

Business Interstate 40-J
Location Shamrock
Length2.77 mi [26] (4.46 km)
Existed1993–present [26]

The Shamrock business loop of Interstate 40 is the last business route of I-40 in Texas, running from exit 161 to exit 164, along historic US 66. Officially designated as Business Interstate 40-J by the Texas Department of Transportation, it is another business route that runs along the south side of I-40 in Texas, rather than the north side.

Route description

Business Interstate 40-J begins at the off-ramp for Exit 161 leading to the I-40 frontage road along the eastbound lanes, which just as in Groom, suddenly becomes a divided highway named "Route 66." After passing a gas station and a former intersection with Wheeler County Road 15, the first intersection with this Business Loop is the unmarked Texas State Spur 556, which is also a connecting road running underneath I-40 leading to the frontage roads along the westbound lanes, as well as the western terminus of the business loop. Unlike Groom, no eastbound on ramp exists here, and the divided highway ends immediately after Spur 556 in order to become a four-lane undivided highway. Further into town former Route 66 gains the name of West 12th Street, and the only signalized intersection along the entire route is U.S. Route 83 in Texas (Main Street) where the NRHP-listed U-Drop Inn can be found on the northeast corner. From there, the road is named East 12th Street. Commercial development along the road, which began four blocks west of US 83 at North Arizona Street, consist mainly of motels, restaurants, and local car culture oriented businesses, some of which focuses on the roads former status as Route 66. The commercial strip ends after a dirt road named North Tennessee Street.

"Route 66" splits from East 12th Street at an intersection that's another connecting road to the eastbound off-ramp of Exit 164, the then runs over the overpass above I-40 to turn right at the frontage road along the westbound lanes leading to the western beginning of the business loop. Eastbound Business Interstate Route 40-J narrows down to a two-lane undivided highway before passing by a TxDOT construction and maintenance facility, and then leaves the frontage road at the on ramp to eastbound I-40, where it meets it's terminus. The frontage roads along both sides of I-40 continue through three more interchanges before crossing the Texas-Oklahoma State Line.

Oklahoma

Erick

Interstate 40 Business
Location Erick

The Erick business loop of Interstate 40 is the first business route of I-40 in Oklahoma. It begins on exit 5 (Honeyfarm Drive) and runs south into North 1720th Road until that street ends at a four-lane divided highway known as East 1240th Road ( former Route 66), where it turns east. The next intersection is Oklahoma State Highway 30, which overlaps Bus. I-40 from that point on. BL-40/OK 30 ends as a divided highway at Williams Street, and becomes Roger Miller Boulevard as it enters downtown Erick. The overlap with SH-30 ends at Sheb Wooley Avenue when SH-30 itself turns north. BL-40 becomes a divided highway again east of North 1750th Road, and continues east until the intersection with a dirt road named North 1770th Road, where it curves to the northeast. BL-40 finally ends at a folded-diamond interchange with I-40, known as exit 11.

Sayre

Interstate 40 Business
Location Sayre

The Sayre business loop of Interstate 40 is the second business route of I-40 in Oklahoma. It runs north from exit 20 overlapping much of U.S. Route 283 until leaving that overlap across from the intersection with West Sayre Avenue. From there it runs east-northeast until it reaches a diamond interchange with I-40 at exit 25. Beyond exit 25, the road continues as a jughandle frontage road leading to East 1170th Road.

Elk City

Interstate 40 Business
Location Elk City

The Elk City business loop of Interstate 40 is the third business route of I-40 in Oklahoma. It runs northeast along former US 66 from eastbound exit 32 and turns east after the beginning of an overlap with OK 6 that runs along the route until OK 6 turns south at North Main Street. From there it snakes through the northeastern part of the city and after the intersection with OK 34 finally terminates with I-40 at westbound exit 41.

Route description

The route begins at a left exit in a wye interchange with Interstate 40, which also serves as a connection to southbound Oklahoma State Highway 34. The first intersection along this route is BK 29, which leads to OK 34, and was the west end of an overlap with OK 34 until 1987. The road continues to run northeast, then after encountering an intersection with OK 6, which joins BL-40 in a concurrency, it turns straight east. Just after James Way, the divided highway is replaced by a four lane undivided boulevard with center left turn provisions, and the road approaches the National Route 66 Museum. As the road approaches downtown Elk City, OK 6 turns south at the intersection with North Main Street.

Crossing a bridge over a tributary to Elk Creek, BL-40 makes a sharp curve to the left and heads north at Third Street. Between BK 35 and Country Club Drive, the road not only turns to the east again, but also resumes its previous status as a divided highway. Here it also passes by the Elk City Regional Business Airport. The approach to the intersection with OK 34 is a sign of the beginning of the end for BL-40, because south of this intersection is an approach to a westbound on-eastbound off wye interchange with I-40. Immediately after this intersection, BL-40 ends at an eastbound on-westbound off wye interchange with I-40.

Major intersections

The entire route is in Beckham County.

Clinton

Interstate 40 Business
Location Clinton

The Clinton business loop of Interstate 40 is the fourth business route of I-40 in Oklahoma, running from exit 65 to exit 69, along former US 66.

Route description

The route begins at exit 65, which is an eastbound flyover with no re-entry, and a westbound right-in/right-out configuration. It runs northeast along West Gary Boulevard, a four-lane divided highway with a grassy median, surrounded by commercial development, including Clinton High School, then the Oklahoma Route 66 Museum just south of the eastern terminus of Oklahoma State Highway 73. The divider becomes less prominent north of that intersection, briefly becoming non-existent in some areas. The road runs parallel to a Burlington Northern and Santa Fe Railway line until it curves east before the intersection with North 15th Street, and continues to run straight east throughout much of downtown. With some exceptions, BL 40 continues as a standard commercial strip. Those exceptions consist of historic looking buildings such as the First Presbyterian Church on the southwest corner of North 7th Street, and the former fire station on the northeast corner of North 6th Street.

City Hall can be found on the northwest intersection with US 183 (North 4th Street), and east of that intersection the surroundings are slightly more industrial. At North First Street, the route crosses an abandoned railroad line that was paved in that street as the name is briefly changed to Choctaw Avenue, then crosses a non-abandoned former Kansas City, Mexico and Orient railroad line now run by the Farmrail and Grainbelt Railroads. [27] Immediately after the intersection with South Glenn Smith Street, the road runs along the Bridge over the Washita River, and the name is reverted to Gary Boulevard where it becomes more rural. Curving around a former Rock Island Railroad line, the road becomes a divided highway with a wide grassy divider again, just before the entrance to the Clinton Indian Health Center, the headquarters of the Cheyenne and Arapaho Tribal Government [28] and a branch of the Lucky Star Casino. [29] The last intersection is North 2280th Street before BL 40 ends at a wye interchange with I-40 at exit 69.

Sallisaw

Interstate 40 Business
Location Sallisaw

The Sallisaw business loop of Interstate 40 is the last business route of I-40 in Oklahoma, running from exit 308 ( US 59) to exit 311 ( US 64).

Route description

BL-40 begins at a diamond interchange with I-40 at Exit 308, and then turns north along US 59 (South Kerr Boulevard) as it passes under I-40. The road is a commercial strip that runs at a slight north-northwest angle and serves as a four-lane undivided highway with occasional provisions for left-turn lanes. South Kerr Boulevard curves slightly to the north-northeast where it ends at West Cherokee Avenue (US 64), and both BL-40 and US 59 join US 64 along West Cherokee Avenue in a concurrency. The road narrows down to two lanes and runs beneath a Kansas City Southern Railroad line, but emerges from beneath the bridge to enter "downtown" Sallisaw as a two-lane concrete road with parallel parking, and run parallel to a former Missouri Pacific Railroad line, now owned by Union Pacific Railroad. The former MoPac Depot is now the Stanley Tubbs Memorial Library.

US 59 leaves the overlap at North Wheeler Avenue and BL-40 continues to follow US 64, along East Cherokee Avenue, which become a four-lane undivided highway before Wheeler Avenue. East of North Dogwood Street, BL-40/US 64 curves to the southeast, away from the former MoPac line, and resumes as a standard contemporary commercial strip. Between Jenkins Street and Doris Drive, the road runs along a bridge over Hog Creek. BL-40 ends at a partial cloverleaf interchange with I-40 known as Exit 311, while US 64 continues towards the Sallisaw Sports Complex, Muldrow, and Moffett, where it crosses the J. Fred Patton Garrison Avenue Bridge over the Arkansas River and the Oklahoma-Arkansas State Line.
