Interstate 25
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 These roads typically follow along local streets often along a former U.S. route or state highway that had been replaced by an Interstate.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 25 (I-25), business routes are found in all three states through which I-25 passes: New Mexico, Colorado, and Wyoming. 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. Every state along I-25 regards its business routes as fully incorporated members of their respective state maintained highway systems.

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.

New Mexico[edit]

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 Interstate 25 (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. I-25 begins with a business route through Williamsburg and Truth or Consequences before proceeding northward with additional routes serving the towns of Socorro, Belen, Las Vegas, Springer, and Raton. These routes largely conform to the current or former alignment of the unsigned U.S. Route 85 (US 85) through these communities before the construction of I-25. NMDOT has decommissioned US 85 throughout the state and no longer signs the highway along its length as US 85 entirely follows I-25 with the single exception of the business loop in Las Vegas. The American Association of State Highway and Transportation Officials (AASHTO), however, continues to recognize the New Mexico portion of US 85 maintaining continuity with sections in adjacent states.

Williamsburg – Truth or Consequences[edit]

Business Loop 11
Location: WilliamsburgTruth or Consequences
Length: 5.711 mi[1]:1 (9.191 km)

Business Loop 11 is a 5.7-mile (9.2 km) business loop serving the cities of Williamsburg and Truth or Consequences in Sierra County. The loop begins at Exit 75 of I-25 in Williamsburg, intersecting State Road 187 (NM 187), traveling northeast on Broadway Street through Truth or Consequences until meeting Main Avenue. Between that point and Date Street, the route follows two one way roads with Broadway carrying northbound traffic and Main conveying traffic to the south. The routes combine and turn north on Date, intersecting the western terminus of NM 51. Turning northwest, the highway intersects NM 181 and terminates at Exit 79 on I-25 on the north side of Truth or Consequences.[2]:1[3]

Most of the loop, with the exception of its I-25 interchanges, was previously part of US 85 which joined the route from the south at NM 187[4]:43 and departed to the north along NM 181.[4]:42

Major intersections

The entire route is in Sierra County.

Colorado[edit]

All Interstate business routes are maintained by the Colorado Department of Transportation (CDOT). Within Colorado, all highways maintained by the state are classified as state highways including Interstates and U.S. routes which hold the same numerical designations as their nationally established routes. The numerical values of all state highway names are followed by an alphabetic suffix, although this convention is used by the department internally and not reflected in route signage. Hence, the mainline of Interstate 25 throughout the length of the state is classified as State Highway 25A while its two business routes in Aguilar and Walsenburg are internally named State Highway 25B and State Highway 25C respectively. US 85 and US 87 are hidden routes not recognized nor signed by CDOT in southern Colorado. They are, however, established AASHTO routes maintaining continuity with signed portions in other states along their routes. In southern Colorado, the routes primarily follow I-25 including at Aguilar but with deviations such as along the Walsenburg business route. In addition to these, US 160 joins I-25 at Walsenburg and follows concurrently with the Interstate to Trinidad including the portion bypassing Aguilar. Thus in Walsenburg, US 160 crosses the business route in the town center and again at the business route's southern terminus.

Aguilar[edit]

State Highway 25B
Location: Aguilar
Length: 1.981 mi[11] (3.188 km)

State Highway 25B is a business spur of I-25 connecting the town of Aguilar in Las Animas County to the Interstate. The 2.0-mile (3.2 km) route begins at the corner of Main Street and First Street in Aguilar. The spur proceeds for one block north along N. First St. before turning to the northwest along Lynn Rd. away from town. The route turns east along County Road 60 immediately before terminating at I-25 Exit 34.[11][12]

Walsenburg[edit]

State Highway 25C
Location: Walsenburg
Length: 4.356 mi[13] (7.010 km)

State Highway 25C is a business loop of I-25 serving the town of Walsenburg in Huerfano County. The route 4.4-mile (7.1 km) begins at I-25 Exit 49 and proceeds to the west along the southern edge of Walsenburg. The route then turns to the northwest along Walsen Avenue. At Seventh Street, US 160 intersects from the west. US 160 runs concurrently with the loop until US 160 turns off to the east along Fifth Street to I-25. The loop then continues northeast along Walsen Ave. leaving town and intersects State Highway 69 (SH 69) before terminating at I-25 Exit 52.[13][14]

CDOT does not recognize or sign US 85 in the southernmost part of its route within the state, nor does it recognize US 87 anywhere within Colorado as they are redundant with other routes in the state highway system.[15] The highways remain established by AASHTO primarily along I-25 in southern Colorado and along Walsenburg's I-25 business route.[8]

Wyoming[edit]

All business routes of Interstate 25 are maintained by the Wyoming Department of Transportation (WyDOT). Wyoming has no naming convention for disambiguation between different business routes with all designated simply as I-25 Business along the Interstate. I-25 has four business routes within the state including loops in Cheyenne, Douglas, and Casper along with a spur in Buffalo. Road concurrences are frequent in Wyoming, and the four business often overlay multiple other highways including US 87 Bus. wholly or partly at all four locations as US 85 largely follows I-25 throughout the state.

Cheyenne[edit]

Interstate 25 Business
Location: Cheyenne
Length: 8.006 mi[16]:101-102 (12.88 km)

Interstate 25 Business is a business loop serving the city of Cheyenne in Laramie County. The 8.0-mile (12.9 km) highway begins at Exit 7 of I-25 and US 87 and is routed along Wyoming Highway 212 (WYO 212) and is named College Drive. At just over two and a half miles, US 85 is intersected. Here, I-25 Bus. leaves WYO 212 and turns north onto US 85 and will remained paired with it until its end. I-25 Bus. and US 85 enter Cheyenne from the south and intersect I-80 at Exit 362. At this point I-180 begins while US 87 Bus. joins the route from the west. Despite the Interstate designation, the I-180 portion is not a freeway. The I-180 concurrency only lasts for just over one mile as I-180 ends at I-80 Bus. / US 30 along Lincolnway. I-25 Bus. continues north with US 85 and US 87 Bus. now as a one-way couplet through central Cheyenne northbound as Warren Avenue and southbound as Central Avenue. Near the Cheyenne Regional Airport, the one-way streets combine and continue as Central Avenue before intersecting the southern terminus of WYO 219 at Yellowstone Avenue. I-25 Bus. and US 87 Bus. terminate at Exit 12 of I-25 / US 87. Here US 85 joins those routes northbound.[16][17]
