Twin Falls is the largest city in Idaho that is not directly on the Interstate Highway System; it is served by several major highways, including U.S. Route 30 and U.S. Route 93. Access to nearby Interstate 84 is across the canyon via the Perrine Bridge (U.S. 93); the junction is approximately north, in Jerome County. State Highway 74 provides direct access from downtown Twin Falls to southbound locations on U.S. 93, including Hollister and Rogerson, then crosses into Nevada at Jackpot and continues to a junction with Interstate 80 at Wells.
