Vehicular traffic is permitted across the crest of the Hoover Dam via the U.S. Route 93. This roadway connects Arizona and Nevada, providing a crucial transportation link between the two states. Before 2010, this route was a two-lane highway directly atop the dam, resulting in significant congestion and safety concerns. The Mike O’CallaghanPat Tillman Memorial Bridge, completed in 2010, now bypasses the dam structure itself, offering a safer and more efficient passage for vehicles.
The ability to traverse the dam historically facilitated interstate commerce and tourism, contributing significantly to the region’s economic development. The construction of the bypass bridge improved safety and traffic flow, while preserving access to the dam for visitors. The dam itself remains a significant landmark and engineering marvel, drawing visitors from around the world. The bridge enhances the visitor experience by providing spectacular views of the dam and surrounding Black Canyon.
