McKissack provided design-build services to the District Department of Transportation (DDOT) to reconstruct the 11th Street Corridor.
McKissack provided design-build services to DDOT to reconstruct the 11th Street Corridor, including replacement of the existing bridge spans over the Anacostia River in Southeast Washington, DC. McKissack provided the design for the streetcar system across the local bridge span and other design support services, as well as quality assurance/quality control, and construction inspection services. These inspection services included overseeing geotechnical investigations, concrete and steel testing, and preparing all the required documents. This mega project will separate local and commuter traffic and accommodate pedestrians, bicyclists and a light rail system. The freeway bridges will connect the Anacostia Freeway and the Southeast Freeway, providing the missing movement from the north to the east and the east to the north.
