Interstate 80 Business (BL-80) is an unofficial business loop of Interstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of U.S. Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with U.S. Route 93 Alternate (US 93 Alt.), and the entire portion in Utah is coterminous with Utah State Route 58 (SR-58). The Nevada Department of Transportation (Nevada DOT) applied for the business loop designation in the early 1980s but the designation has never been approved; nevertheless, signs are posted in both states. Between July 1976 and 1993, BL-80 was concurrent with State Route 224 (SR 224) in Nevada.
