A $441 million replacement bridge, Frederick Douglass Memorial Bridge, will replace a 68-year-old bridge spanning the Anacostia River and connecting the District with areas to the southeast.
AECOM is the lead designer of the three-arch bridge, and a joint venture between Archer Western Construction and Granite Construction will serve as general contractor.
The bridge is scheduled to open in late 2021.
The Federal Highway Administration will allocate $200 million in federal funds to the project.
According to DDOT, which is working with HNTB to manage the project, it’s the biggest construction job in the district’s history.
The current Frederick Douglass Memorial Bridge, which opened to traffic in 1950, is a steel swing bridge that has suffered considerable corrosion over the years, and rarely opens for oversize river traffic. It underwent a $27 million rehab in 2007 in order to extend its life until a replacement bridge could be designed and built.
