In 2005, Hurricane Katrina destroyed the Bay St. Louis Bridge in Mississippi, on U.S. 90. Within 6 months, MDOT had proceeded with the state’s first ever “design/build” contract, which was awarded to a Joint Venture of Archer Western Contractors and Granite Construction Company. The 2.1 mile long replacement bridge was built with a mid-span height of 85 ft, some 55 ft higher than the damaged structure, eliminating the need for a draw span. The bridges contain epoxy-coated reinforcing steel to withstand exposure to saltwater.

The bridge is decorated with brass art pieces and mile-markers on the pedestrian pathway of the Bay St. Louis Bridge. These plaques were sculpted by Greg Moran who used recovered brass bearing plates from the damaged Biloxi Bay bridge.
