Interstate 80 Business (I-80 Bus) is an unofficial business loop of Interstate 80 (I-80) that is 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 US Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with US 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 (NDOT) 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, I-80 Bus was concurrent with Nevada State Route 224 (SR 224) in Nevada. Route description Starting at the easternmost Nevada exit of I-80, I-80 Bus heads south along Florence Way, concurrent with US 93 Alt until it intersects with, and turns east onto Wendover Boulevard. Just west of the intersection, the highway passes the West Wendover City Hall, which houses the West Wendover Municipal Court and Eastline Justice Court. Traveling east along Wendover Boulevard, I-80 Bus passes by the Peppermill Wendover casino, the West Wendover Visitors Center, and Scobie Park. US 93 Alt turns south toward Ely, while I-80 Bus continues east until it reaches the Montego Bay Resort and Wendover Nugget casinos. The casinos are connected via a skybridge that allows pedestrian access between the hotels without crossing the highway. A line painted on the street marks the Nevada–Utah border. At the border, I-80 Bus becomes coterminous with SR-58 for the final stretch through Wendover, Utah. I-80 Bus continues to the east past Aria Boulevard, which to the north connects to I-80 and to the south leads to the historic Wendover Air Force Base, where the 509th Composite Group was stationed while it prepared to conduct atomic bomb attacks against Japan during 1944 and 1945. The highway briefly parallels the Shafter Subdivision of the Union Pacific Railroad's Central Corridor, which was formerly part of the Feather River Route of the Western Pacific Railroad. As the highway travels east toward a half trumpet interchange with I-80, the number of lanes drops from five to two. Traffic from I-80 Bus can access eastbound I-80 or turn off onto Frontage Road; however, to access westbound I-80, travelers
