Hoover Dam Bypass, Las Vegas

Drive the 5.6 km (3.5 m) Hoover Dam Bypass to see a massive concrete dam, travel the longest single-arch bridge in North America, and cross state lines. The highlight of the bypass is the Mike O’Callaghan - Pat Tillman Memorial Bridge. Standing 260 m (840 ft) above the Colorado River, the bridge is the second highest in the United States. It offers fantastic views of the Hoover Dam, a Depression-era engineering wonder, and Lake Mead. If you are interested in learning about the dam’s history, stop and take a tour. Park in one of the nearby lots if you would like to walk the bridge and take photos. Continue to the middle to see the state line marker. For free parking, cross to the Arizona side.
