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 These roads typically follow along local streets often along a former U.S. Route or state highway that had been replaced by an Interstate.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. The Interstate has no business routes along its passage through Arkansas nor Tennessee, and there once was a business route in North Carolina, but it was decommissioned in 2020.
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 (US66).
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).[1]
Interstate40 Business (I-40 Bus.) is a business loop of I-40 through Needles in San Bernardino County that begins at exit141 of I-40/US95 northwest of town. The unsigned highway follows Broadway to the southeast to Needles Highway, then eastward through an underpass of I-40 into the town center. At NStreet, the loop turns southward into the southern part of town where it reconnects with Broadway. The route then continues southeastward to I-40 exit144 where it terminates and US95 continues southward along Broadway. The route largely follows the former route of US66 through town except where the historic highway's path has since been disrupted by the construction of I-40.[2]
The business loops within Arizona are maintained by the Arizona Department of Transportation (ADOT) and by municipal authorities. I-40 has five business loops within the state located in Seligman, Ash Fork, Flagstaff, Joseph City, and Holbrook, and a business spur in Winslow. The state formerly had business loops in Kingman and Winslow, as well as a second loop in Flagstaff. ADOT internally identifies each Interstate business route as a State Business Route with 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.
State Business Route40 (0) (SR40B (0)) was a former business loop of I-40 at Kingman in Mohave County. The 3.7-mile (6.0km) loop began at I-40 exit48 where US93 approaches the intersection from the west along Beale Street and joins the Interstate while the loop proceeded eastward along Beale Street. After a short distance, the loop joined Andy Devine Avenue which carried the former US66. The loop turned northward, returning to I-40 and US93 at exit53 where the loop terminated, but the roadway continues forward, carrying SR66.[3][6]
State Business Route40 (1) (SR40B (1)) is a business loop of I-40 at Seligman in Yavapai County. The 4.24-mile (6.82km) loop begins at I-40 exit121 on the west end of town and proceeds northward, passing over the former SR66, a local road still signed as a state route that is a former alignment of US66. The loop then takes a semicircular path near the Seligman Airport, returning to Historic US66, where the loop turns east through town. At the eastern edge of town, the loop turns south, returning to I-40 at exit123.[3]:418[9]
State Business Route40 (2) (SR40B (2)) is a business loop of I-40 through Ash Fork in Yavapai County. The highway is co-signed with Historic U.S. Route 66 for its entire length. The 1.5-mile (2.4km) loop begins at I-40 exit145 and proceeds to the northeast along the western edge of town. The loop passes through town as a divided route with eastbound traffic following Park Avenue and westbound traffic routed along Lewis Avenue. The roadways combine on the east end of town, and the loop returns south, terminating at I-40 exit146. The roadway continues south beyond I-40 as SR89.[3]:419–420[10]
State Business Route40 (3) (SR40B (3)) was a business loop of I-40 through Williams in Coconino County. The four-mile (6.4km) loop began at I-40 exit161 west of Williams and took US66 into town. In the town center of Williams, the eastbound and westbound lanes of the loop diverged into a oneway pair near 9thStreet. The eastbound lans used the appropriately named "Route66" while the westbound utilized Railroad Avenue. A junction at 2ndStreet provided access to I-40 exit163 and the Grand Canyon Railway station. East of town, the westbound and eastbound lanes of the loop reconverged. The loop curved northeast at Bearizona Wildlife Park before arriving at a junction with I-40 exit165, the diamond interchange served as the eastern terminus of the loop. The road continued straight ahead as SR64, which has its western terminus at exit165.[11] This route was a former section of US66 and US89.[13] On August16, 1990, ownership and maintenance of the business route was handed over to the city of Williams, and the designation was decommissioned.[11][14]
State Business Route40 (4) (SR40B (4)) is a business loop of I-40 through Flagstaff in Coconino County. The 6.7-mile (10.8km) loop begins at I-40 exit191 west of Flagstaff and enters the city following the former route of US66. In central Flagstaff, the loop intersects SR89A at Milton Road. The loop turns north and follows Milton Road and then turns east along the street known as Route66 (formerly Santa Fe Avenue) before intersecting US180 at Humphreys Street. The loop continues to the east side of Flagstaff, where Route66 diverges carrying the former alignment of SR40B (5), before intersecting US89. From this intersection, the loop turns southward along Country Club Drive until terminating at I-40 exit201.[16]:663–667[17]
State Business Route40 (5) (SR40B (5)) was a former business loop on the eastside of the city of Flagstaff in Coconino County. The 4.6-mile (7.4km) loop began at the combined route of SR40B and US180 and followed Santa Fe Avenue eastward, underpassing the current business route. The loop continued along the former US66, connecting with I-40 and US180 at exit204 for Walnut Canyon Road along the city's eastern edge. The loop was decommissioned in 2008 and returned to the city for maintenance.[3]:423[16]:668[18]
Interstate 40 Business Spur or State Route40 Spur (BS40 or SR40Spur) is a business spur of I-40 located in Navajo County serving the city of Winslow. The 1.2-mile (1.9km) spur begins at I-40/US180 exit252 and follows Hipkoe Drive south while concurrent with SR99. At the intersection with 3rdStreet, the two highways split; SR99 heads east, while SR40S heads west. After crossing over the BNSF railway, the spur continues for 0.19 miles (0.31km), ending just north of the intersection of Cooperstown Road and the county line.[19]
BS 40 was originally designated US66 Spur on June 15, 1970.[20] The route was re-routed onto a new alignment on August 23, 1974.[21] US66 Spur was redesignated as BL40Spur on October 26, 1984, when US66 and all of its associated suffixed routes in Arizona were decommissioned and redesignated as SR66 or business routes of I-40, where US66 wasn't concurrent with I-40.[22]
State Business Route40 (8) (SR40B (8)) in Holbrook runs along part of current US180 and former US66 as well as SR77 from exit285 to exit289.

New Mexico
All of the business loops within New Mexico are maintained by the New Mexico Department of Transportation (NMDOT). In New Mexico, Interstate business routes are named independently of their parent Interstate's designation, with business loops of I-25 numbered between 10–19, those of I-10 between 20–29, and those of I-40 between 30–39. New Mexico business loop numbers ascend eastward and northward with gaps in numbering to allow for future designations. Within New Mexico, I-40 currently has business routes in Moriarty, Santa Rosa, and Tucumcari.
Business Loop31 (BL31) in Gallup is a former business loop that ran along part of former US66 from an interchange at exit16 to another interchange at exit26.
This section needs expansion. You can help by adding to it. (March 2018)
Business Loop32 (BL32) in Grants is a former business loop that ran along part of former US66 from an interchange at exit79 in Milan to another interchange at exit 85. It also had a connecting spur at exit81.
This section needs expansion. You can help by adding to it. (March 2018)
Business Loop33 (BL33) in Albuquerque is a former business loop that ran along part of former US66 from a former Y-interchange at eastbound exit149 to a half diamond/partial cloverleaf interchange at exit167. The Y-interchange was rebuilt between 2009 and 2011 for Atrisco Vista Boulevard for the conversion of that interchange from a westbound half diamond interchange to a full diamond interchange. The route followed Central Avenue through downtown Albuquerque from I-40 at Tramway Boulevard (NM-556) to Atrisco Vista Boulevard (NM-500). The Business Loop 40 designation was removed from Central Avenue in the 1990s when NMDOT turned over ownership and maintenance of Central Avenue to the City of Albuquerque, although some remnant BUSINESS 40/US-66 remain along Central Avenue.
This section needs expansion. You can help by adding to it. (March 2018)
Business Loop34 (BL34) in Moriarty runs along part of former US66. It begins at a trumpet interchange at exit194 and begins traveling east, intersecting State Road333 (NM333). It continues west after that, intersecting NM 41 before reaching its eastern terminus at a flyover interchange with an additional east-to-west ramp at exit197.
Business Loop35 (BL35) in Santa Rosa runs along former US66 from exit273 to exit277. It also overlaps part of US54 and all of US84. Along the way, it also intersects the northern terminus of NM 91.
Business Loop36 (BL36) in Tucumcari runs along part of former US66 from a trumpet interchange at exit329 to a diamond interchange at exit335. It intersects NM 104 and NM 209 in the center of Tucumcari.
The business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). I-40 has seven business loops in the state, all located in the Panhandle region. TxDOT identifies each business route as Business Interstate40 followed by an alphabetic suffix. Along Texas Interstates, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion. The alphabetic naming suffixes are included as small letters on the bottom of reassurance shields.
Business Interstate40-A (Bus. I-40-A) is a business spur of I-40 in Glenrio that begins at I-40 exit0 just east of the New Mexico–Texas state line. The highway runs south from the interchange toward former US66, then turns west along that decommissioned route where it terminates at the Texas–New Mexico state line.
Business Interstate40-B (Bus. I-40-B) is a business loop of I-40 in Adrian that begins at I-40 exit22 and runs along former US66 to exit23, the latter of which also includes the northern terminus of State Highway214 (SH214).
Bus. I-40-B begins and ends at on- and offramps leading to and from two-way frontage roads along I-40, which, in the case of the one on the northbound side, is a genuine former section of US66. Eastbound Bus. I-40-B immediately turns north on Oldham County Road22, which runs across an overpass above I-40 before terminating at Historic US66, then turns right, where it encounters the official Midway Point of Historic US66, as well as a cafe 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 offramp for exit22, which is the official westbound beginning of Bus. I-40-B, eastbound Bus. I-40-B runs toward the northern terminus of SH214, 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 onramp ending at I-40 itself.
Business Interstate40-C (Bus. I-40-C) is a business loop of I-40 in Vega that runs along former US66 between two modified trumpet interchanges at exit35 and exit37.
Bus. I-40-C begins and ends at on- and offramps leading to and from two-way frontage roads along I-40, which, in the case of the one on the northbound side, is a genuine former section of US66. Eastbound Bus. I-40-C immediately turns southeast, away from the former Choctaw, Oklahoma and Gulf Railroad line, which was acquired and later abandoned by the Rock Island Railroad.[30] The surrounding landscape is completely barren until the road encounters a hotel. From 14th to 13thstreets, the road curves from southeast to straight east. The sole main intersection along the route is US385 (South Main Street), which contains intersection beacons. Though all of Bus. I-40-C is named Route66, as well as Vega Boulevard, an older segment of the iconic route turned north in an overlap with US385, and turned west onto West Main Street ending just east of where the intersection with the eastbound exit35 ramps are. Between 7th and 6thstreets, Bus. I-40-C passes a TxDOT construction and maintenance facility and then curves southeast again east of 3rdStreet to follow along the southside of the former Choctaw Route. After the intersection with 1stStreet, the surroundings become barren once again, with the exception of one ranch on the southside. Bus. I-40-C ends at exit37 on I-40, and the former segment of US66 along the northside continues as one of the two I-40 frontage roads.
Business Interstate40-D (Bus. I-40-D) is a business loop of I-40 in Amarillo that begins at I-40 exit62A just west of Amarillo. The highway was formerly a business route for US66, being that highway's only bannered route in Texas. Bus. I-40-D is known locally as Amarillo Boulevard and is the longest business route of I-40.
Bus. I-40-D begins at I-40 exit62A 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 State Highway Loop335 (Loop335, Soncy Road). Bus. I-40-D turns northeast at an interchange with Coulter Street/Wolffin Avenue before briefly running north at an interchange with Southwest 9thAvenue/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 North Western Street interchange. After this interchange, Bus. I-40-D begins to travel through a heavily developed area of the city before meeting US60/US87/US287 just north of downtown and begins an overlap with US60. The two highways continue to travel through a heavily developed area of the city, with the development becoming more sparse after the SH136 intersection. Bus. I-40-D becomes a divided highway after an interchange with Loop335 (Lakeside Drive) and runs along the northern border of Rick Husband Amarillo International Airport. Just after leaving the Amarillo city limits, US60 leaves the highway and Bus. I-40-D starts to run southeast. Bus. I-40-D meets its eastern terminus at I-40 exit85.
Business Interstate40-F (Bus. I-40-F) is a business loop of I-40 in Groom that begins at I-40 exit110 and runs along former US66 to exit114. It is one of the few business routes to run along the southside of I-40 in Texas, rather than the northside.
Bus. I-40-F begins at the offramp for exit110, leading to the I-40 frontage road along the eastbound lanes, which suddenly becomes a divided highway named "Route66". The first intersection is a connecting road to the parts of the interchange with the eastbound onramp, 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 RoadBB. The divided highway ends just west of Farm to Market Road 295 (FM295) and Carson County RoadCC (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 southside lined with numerous massive grain silos along the abandoned Chicago, Rock Island and Gulf Railway line until the intersection with 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 offramp of exit114, 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. Bus. I-40-F ends at the onramp to eastbound I-40, as does the divided former US66, which is converted back into the frontage road along the eastbound lanes of I-40.
Business Interstate40-H (Bus. I-40-H) is a business loop of I-40 in McLean that runs from exit141 to exit143. It begins at I-40 at an eastbound flyover interchange and runs northeast along former US66. Before the intersection with 26th1/2Road, it curves to the southeast. After the intersection with SH273, it splits into a oneway pair with eastbound Bus. I-40-H continuing along Railroad Street and westbound Bus. I-40-H moving onto First Street, one block to the north. This oneway pair runs through the McLean Commercial Historic District and comes to an end just at the intersection with a connecting road that brings eastbound Bus. I-40-H traffic under I-40 and then loops back from the south I-40 frontage road to end at I-40.
Business Interstate40-J (Bus. I-40-J) is a business loop of I-40 in Shamrock that is the easternmost business route of I-40 in Texas, running from exit161 to exit164 along historic US66. It is another business route that runs along the southside of I-40 in Texas rather than the northside.
Bus. I-40-J begins at the offramp for exit161 leading to the I-40 frontage road along the eastbound lanes, which, just as in Groom, suddenly becomes a divided highway named "Route66". After passing a gas station and a former intersection with Wheeler County Road15, the first intersection with this business loop is the unmarked State Highway Spur556 (Spur556), 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 onramp exists here, and the divided highway ends immediately after Spur556 in order to become a four-lane undivided highway. Further into town, former US66 gains the name of West 12thStreet, and the only signalized intersection along the entire route is US83 (Main Street) where the U-Drop Inn, listed in the National Register of Historic Places, can be found on the northeast corner. From there, the road is named East 12thStreet. Commercial development along the road, which began four blocks west of US83 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 US66. The commercial strip ends after a dirt road named North Tennessee Street.
"Route66" splits from East 12thStreet at an intersection that's another connecting road to the eastbound offramp of exit164. Westbound Bus. I-40-J 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 Bus. I-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 onramp to eastbound I-40, where it meets its terminus. The frontage roads along both sides of I-40 continue through three more interchanges before crossing the Texas–Oklahoma state line.
Interstate40 Business (I-40 Bus.) in Erick is a business loop of I-40 that is the first business route of I-40 in Oklahoma. It begins at exit5 (Honeyfarm Drive) and runs south onto North 1720thRoad until that street ends at a four-lane divided highway known as East 1240thRoad (former US-66), where it turns east. The next intersection is State Highway30 (SH-30), which overlaps I-40 Bus. from that point on. I-40 Bus./SH-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. I-40 Bus. becomes a divided highway again east of North 1750thRoad and continues east until the intersection with a dirt road named North 1770thRoad, where it curves to the northeast. I-40 Bus. finally ends at a folded diamond interchange with I-40, known as exit11.
Interstate40 Business (I-40 Bus.) in Sayre is a business loop of I-40 that is the second business route of I-40 in Oklahoma. It runs north from exit20, overlapping much of US-283 as a four-lane divided highway until the intersection with Greer Avenue, where it becomes a four-lane undivided highway. The sole major intersection downtown is West and East Main Streets, which are part of SH-152. Between Maple and Poplar avenues, I-40 Bus./US-283/former US-66 has a grade crossing with a former Rock Island Railroad line, just west of a historic depot. Further north, it passes by the First Baptist Church, as well as the Route66 Farmer's Market. I-40 Bus. and historic US-66 leave 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 exit25. Beyond exit25, the road continues as a jughandle frontage road, leading to East 1170thRoad.

Interstate40 Business (I-40 Bus.) in Elk City is a business loop of I-40 that is the third business route of I-40 in Oklahoma. It runs northeast along former US-66 from eastbound exit32 and turns east after the beginning of an overlap with SH-6 that runs along the route until SH-6 turns south at North Main Street. From there, it snakes through the northeastern part of the city and, after the intersection with SH-34, finally terminates with I-40 at westbound exit41.
Route description
The route begins at a left exit in a Y-interchange with I-40, which also serves as a connection to southbound SH-34. The first intersection along this route is BK29, which leads to SH-34 and was the west end of an overlap with SH-34 until 1987. The road continues to run northeast, then, after encountering an intersection with SH-6, which joins I-40 Bus. 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, SH-6 turns south at the intersection with North Main Street.
Crossing a bridge over a tributary to Elk Creek, I-40 Bus. makes a sharp curve to the left and heads north at 3rdStreet. Between BK35 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 SH-34 is a sign of the beginning of the end for I-40 Bus. because south of this intersection is an approach to a westbound on/eastbound off Y-interchange with I-40. Immediately after this intersection, I-40 Bus. ends at an eastbound on/westbound off Y-interchange with I-40.
Interstate40 Business (I-40 Bus.) in Clinton is a business loop of I-40 that is the fourth business route of I-40 in Oklahoma, running from exit65 to exit69, although only part of the route runs along former US-66.
Route description
The route begins at exit65, which is an eastbound flyover with no reentry, 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 SH-73, and, ironically, west of the original US-66. The divider becomes less prominent north of that intersection, briefly becoming nonexistent 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 15thStreet and continues to run straight east throughout much of downtown. I-40 Bus. does not overlap any former segments of US-66 until 10thStreet. With some exceptions, I-40 Bus. 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 7thStreet and the former fire station on the northeast corner of North 6thStreet.
City Hall can be found on the northwest intersection with US-183 (North 4thStreet), as well as a second leg of former US-66. East of that intersection, the surroundings are slightly more industrial. At North 1stStreet, 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 nonabandoned former Kansas City, Mexico and Orient railroad line now run by the Farmrail and Grainbelt Railroads.[38] 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 and a branch of the Lucky Star Casino.[39][40] The last intersection is North 2280thStreet before I-40 Bus. ends at a Y-interchange with I-40 at exit69.
Interstate40 Business (I-40 Bus.) in Weatherford is a business loop of I-40 that is the fifth business route of I-40 in Oklahoma, running from exit80A to exit82, along parts of former US-66 and Main Street.
Route description
I-40 Bus. begins at an eastbound-only flyunder interchange and runs northeast along Southwest Main Street and runs beneath a railroad bridge for a former Chicago, Rock Island and Pacific Railroad line. Southwest Main Street ends at the southwest corner of the intersection of North and South 7thStreets and West Main Street and the route turns east onto West Main Street. West of this intersection, West Main has no designation but connects to SH-54. West Main Street becomes East Main Street at the intersection with North and South Custer Streets. East of Washington Avenue, I-40 Bus. curves to the northeast then turns right where it ends at another flyunder interchange, while historic US-66 continues onto East Main Street along the north side of I-40. Until sometime in the mid-2010s, this interchange was a trumpet interchange with no east- to westbound ramp.
Interstate40 Business (I-40 Bus.) in El Reno is a business loop of I-40 that is the sixth business route of I-40 in Oklahoma, running from exit119 to exit125, along former US-66, as well as part of US-81.
Route description
I-40 Bus. begins at a trumpet interchange with I-40/US-270, running northeast as a divided highway until the intersection with East 1020thDrive, thereby joining historic US-66 and turning straight east along Sunset Road. After passing by the Federal Correctional Institution of El Reno, the divided road narrows as it enters more developed surroundings. Sunset Road curves to the southeast from Foreman Road and passes through Adams Park, only to curve back straight east before a bridge over the Four Mile Creek Riverbed and the intersection with South Country Club Road.
Between South Ellison Avenue and North Miles Avenue, I-40 Bus. runs beneath a railroad bridge for an old Chicago, Rock Island and Pacific Railroad line that runs northwest to southeast and is now owned by Union Pacific Railroad. Four blocks later, I-40 Bus. intersects US-81 (Chisholm Trail) at South Choctaw Avenue and joins the route in a southbound concurrency. For one block, I-40 Bus./US-81/historic US-66 run south to Wade Street, then the three routes run east for two blocks to Rock Island Avenue, only to turn south again. Rock Island Avenue carries all three routes straight south until the intersection with East Elm Street, where the road shifts to the south-southeast over a railroad bridge for another former Rock Island Railroad line. After this bridge, the road begins to curve more toward the east as it briefly intersects and takes over the alignment of Southeast 27thStreet. I-40 Bus./US-81 avoids a sharp right turn onto South Shepherd Avenue through a long east-to-south turning ramp, but still intersects the western terminus of SH-66. Almost immediately, I-40 Bus. ends at exit125 on I-40/US-270, which is an offset diamond interchange with one south-to-east loop ramp, while US-81 continues south toward Chickasha.
Interstate40 Business (I-40 Bus.) in Henryetta is a business loop of I-40 that is the seventh business route of I-40 in Oklahoma, running from exit237 to exit240, along U.S Highway62 Business (US-62 Bus.) and US-75 Bus., as well as part of US-62 and US-75. It is the first business route along I-40 in the state that is not a former segment of US-66.
Route description
I-40 Bus. begins at a diamond interchange with Creek Mine Road. Immediately after the westbound off- and onramps for I-40, the business routes all turn from north to east onto Hornbeam Road. Hornbeam Road runs east then curves to the northeast until it finally ends at West Main Street just west of 17thStreet, curving smoothly into that street in the process. The routes run along West Main Street through the southern part of the city and eventually intersect the former SH-124 (10thStreet) without a traffic signal. The only indication of that street's current importance are signs directing motorists to the Henryetta Municipal Airport and an RV Park.[41] Traffic signals can instead be found at 6th, 5th, and 4thstreets.

Route description
I-40 Bus. begins at a diamond interchange with I-40 at exit308 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 I-40 Bus. 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 I-40 Bus. continues to follow US-64, along East Cherokee Avenue, which become a four-lane undivided highway before Wheeler Avenue. East of North Dogwood Street, I-40 Bus./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. I-40 Bus. ends at a partial cloverleaf interchange with I-40 known as exit311, while US-64 continues toward 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.
Interstate 40 Business in North Carolina was established in 1992 when Interstate 40 was rerouted onto the mostly newly constructed bypass in southern Forsyth County with some portions of the bypass utilizing a portion of US311. The route follows in Winston-Salem, Kernersville, and Colfax. In November2018, I-40 Bus. was closed around the downtown area of Winston-Salem for improvement. When construction was completed, I-40 Bus. was decommissioned, and the route (US421) that overlapped with I-40 Bus. became the main route on the corridor. Because of this, the I-40 Bus. exit numbers (exits1–17) were replaced by the US421 exit numbers (238–221). Construction was completed February2, 2020.
Also in 2008, another I-40 Bus. existed in Greensboro when I-40 was rerouted to the south of that city. However, I-40 was rerouted through the city after a seven months on the new alignment, and US421 now follows most of its former route.

U.S. Route 80 or U.S. Highway 80 (US 80) is a major east–west United States Numbered Highway in the Southern United States, much of which was once part of the early auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the Pacific Ocean to the Atlantic Ocean. Its original western terminus was at Historic US 101 in San Diego, California. However, the entire segment west of Dallas, Texas, has been decommissioned in favor of various Interstate Highways and state highways. Currently, the highway's western terminus is at an interchange with Interstate 30 (I-30) on the Dallas–Mesquite city line. Its eastern terminus is in Tybee Island, Georgia near the Atlantic Ocean.

There are currently eight business routes of Interstate 94 (I-94) in the US state of Michigan. These business routes connect I-94 to the downtown business districts of neighboring cities. Seven of the eight routes are business loops which bear the Business Loop I-94 designation while one is a business spur that bears the Business Spur I-94. These loops are former routings of I-94's two predecessors in Michigan: US Highway 12 (US 12) or US 25. The westernmost BL I-94 runs through the twin cities of Benton Harbor and St. Joseph along the former routing of US 12 and US 31/US 33 that now includes a section of the Lake Michigan Circle Tour in the state. The loops in Kalamazoo, Battle Creek, Marshall, Albion, and Jackson were also formerly segments of US 12 which were later designated as separate version of Business US Highway 12 through their respective cities before becoming BL I-94s in 1960. The BL I-94 in Kalamazoo was converted into BS I-94 in 2019. The route of the business loop through Ann Arbor was previously US 12 and then later M-14 before receiving its current moniker.
