Business routes of Interstate 80
Interstate 80 Business may refer to several business routes of the Interstate Highway System that connects Interstate 80 with the central business district of various cities bypassed by I-80. The business route in each community is considered a unique route. In many cases, these routes are a former section of a U.S. Route or state highway.
California
Interstate business routes in California are assigned by the California Department of Transportation 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.Sacramento
Interstate 80 Business, called the Capital City Freeway in its entirety, is a business loop of I-80 through Sacramento. Unlike most business routes in California, it is state-maintained and assigned route numbers in the state highway system—part of US Route 50 on its western half and unsigned State Route 51 on its eastern half. The full road is a freeway and carried I-80 until 1981, when the signage and designation of I-80 was transferred to the Beltline Freeway, previously signed as I-880. At that time, AASHTO assigned the I-305 designation to the west half, which met Interstate Highway standards. However, Caltrans has never signed this number, put it on any road signs, or used it internally.Truckee
Interstate 80 Business was a business loop in Truckee. It served as a loop around Truckee near I-80 and traversed through Donner Pass Road. All signs and references to the business loop were removed between 2003 and 2004 as part of the reconstruction of I-80 through the area.Nevada and Utah

West Wendover, Nevada–Wendover, Utah
Interstate 80 Business is a unofficial business route of I-80 in West Wendover, Nevada, and Wendover, Utah, that is southern loop off of I-80 and runs mostly along Wendover Boulevard. Wendover Boulevard was part of the original US Route 40. The western part of the Nevada segment runs concurrently with US 93 Alternate, and the entire segment in Utah is concurrent and coterminous with State Route 58. The Nevada Department of Transportation applied for the business loop designation in the early 1980s, but the designation has never been approved because the Utah Department of Transportation never submitted a similar request. Despite being unofficial, the business loop is signed as such, even in Utah. Between July 1976 and 1993, I-80 Bus. segment in Nevada was entirely concurrent with the former State Route 224.Wyoming
Evanston
Interstate 80 Business Loop is a business loop of I-80 that runs through Evanston in western Uinta County. The business route is coexistent with U.S. Route 189 Business for its entire length. I-80 BL begins at I-80 exit 3; the ramp from westbound I-80 to the business route lies east of the other three ramps of the diamond interchange. The business routes heads east along Harrison Drive, which veers northeast onto 11th Street at the western edge of the city street grid. In the downtown area, I-80 BL turns southeast onto Front Street. At the intersection of Front Street and 6th Street, which is the northern terminus of Wyoming Highway 150 and the southern terminus of WYO 89, the business route turns north and crosses the Union Pacific Railroad's Evanston Subdivision rail line. I-80 BL crosses the Bear River, then turns east onto Bear River Drive while WYO 89 continues north. The business route follows Bear River Drive east, then meets I-80 again at exit 6, before terminating at the Bear River State Park rest area south of the Interstate.;Major intersections
Fort Bridger–Lyman
Interstate 80 Business is a business loop of I-80 that has a length of through Fort Bridger and Lyman in eastern Uinta County. The business route begins at I-80 exit 34 where it heads east across Blacks Fork of the Green River and passes through the unincorporated town of Fort Bridger, which contains the namesake historic fort. I-80 BL intersects WYO 414 in the hamlet of Urie then curves north onto the town of Lyman. The business route follows Main Street, then intersects the southern end of WYO 413 within a sharp curve east onto Clark Street. I-80 BL leaves the town and curves northeast, then crosses Smiths Fork, a tributary of Blacks Fork, before rejoining I-80 at exit 48.Green River
Interstate 80 Business is a business loop of I-80 within Green River that spans through Green River in western Sweetwater County. The business route is coexistent with U.S. Route 30 Business for its entire length and avoids the Green River Tunnel on I-80. I-80 BL begins at exit 89, a trumpet interchange that connects with the eastern terminus of WYO 374. The highway heads southeast parallel to the Green River along Flaming Gorge Way through the center of Green River. Near the east end of the city, I-80 BL parallels a Union Pacific Railroad railyard that serves as the western end of the railroad's Rawlins Subdivision and the eastern end of the Evanston Subdivision. Next to the railyard, the business route has an intersection with WYO 530, which heads north, then curves back south and bridges the business route and the railyard on its way to the portion of the city south of the Green River. Immediately east of WYO 530, I-80 BL rejoins the mainline Interstate at exit 91, another trumpet interchange.;Major intersections
