33-Mile Barrier via Design Build

The U.S. Army Corps of Engineers was the lead agency for this 33-mile border fence/vehicle barrier in the Cabeza Prieta National Wildlife Refuge along the Arizona-Mexico border. It was designed to keep vehicles from crossing into the U.S. at non-authorized locations and can restrain a five-ton truck traveling at 40 miles per hour.

As a part of a team, Psomas provided the engineering design for this fast-tracked design-build project including layout of the barrier, adjoining access road, and extensive stormwater analysis. In addition, the Psomas survey group was responsible for the boundary survey and aerial mapping of the U.S.-Mexico border.
