The Federal Highway Administration has approved the Record of Decision (ROD) for the Hoover Dam Bypass Project Final Environmental Impact Statement!

Approval of the ROD is the final step in the process and formal selection of the Sugarloaf Mountain Alternative as the best alternative to minimize environmental impacts, resolve the traffic congestion and accidents at the dam, and increase protection of the dam and waters of the Colorado River. Read the U.S. Department of Transportation press release for the ROD here.

The Hoover Dam, one of the most spectacular structures in the world, is located along U.S. Highway 93 (U.S. 93), the main highway between Arizona and Nevada, and central to the Lake Mead National Recreation Area. Due to growth in population and commerce in the Southwest, the roadway at Hoover Dam has experienced a tremendous increase in traffic over the past 30 years, resulting in increased safety hazards to motorists, pedestrians and the dam itself.

To address the impact of increased traffic across Hoover Dam, federal, state, and local governments have worked for years to find a solution to assure mobility and solve these safety problems. This phase of the Hoover Dam Bypass Project is a continuation of efforts that began in the 1960s. The goal of this project is to evaluate an alternative crossing of the Colorado River near Hoover Dam to accommodate truck and through-vehicle traffic.

It is the goal of this website to disseminate information to all interested parties regarding this site. In addition to the links above and to the left, you may click on any of the three alternative routes on the map to be taken to a page describing the route. Your feedback is always welcome, please email the project with your comments.
