Gov. Harry W. Nice/Sen. Thomas 'Mac' Middleton Bridge Replacement Project

completed

The $463-million project replaced an aging 1.9-mile Potomac River crossing with a new structure featuring long-span prestressed concrete girders on the approaches and steel plate girders over the navigation channel. Doubling the crossing's capacity from two to four lanes enhances regional mobility, emergency response, and long-term operational performance. The project included a robust subsurface investigation to de-risk foundation work and was completed under budget, opening three months early. Concrete debris from the demolished structure was repurposed to create new aquatic habitat in the Chesapeake Bay.
