The National Environmental Policy Act (NEPA) requires federal agencies to assess the social, economic, and environmental impacts of a proposed action for projects that may utilize federal funding. The Federal Highway Administration in cooperation with the Nevada Department of Transportation (NDOT), Arizona Department of Transportation (ADOT); U.S. Army Corps of Engineers (USACE); U.S. Coast Guard (USCG); and Regional Transportation Commission of Southern Nevada (RTC) conducted an Environmental Assessment (EA) for the proposed new bridge over the Colorado River between Laughlin, Nevada and Bullhead City, Arizona. This newly proposed bi-state bridge project would be in addition to the existing four-lane Laughlin Bridge that crosses the Colorado River at approximately 1.9 miles south (downstream) of Davis Dam and approximately 12.4 miles north (upstream) of the proposed bridge.
An Environmental Assessment (EA) is one of the approaches used in the NEPA process to accomplish the above-mentioned goals. The assessment is a concise federal document available to the public that provides sufficient evidence and analysis to allow the lead agency to determine whether there will be significant adverse social, economic, and environmental impacts. For the Laughlin-Bullhead City Bridge Project, the FHWA’s Nevada Division is the lead agency.
