Columbus Plaza Environmental Assessment

Columbus Circle (roadway)/Columbus Plaza (NPS property) is located in northeast Washington, D.C. The project area is bounded by North Capitol Street on the west; Second Street, NE on the east; H Street, NE on the north; and Massachusetts Avenue, NE on the south. The District of Columbia Department of Transportation (DDOT), in conjunction with the National Park Service (NPS), the Union Station Redevelopment Corporation (USRC), and the Architect of the U.S. Capitol (AOC), and in cooperation with the National Capital Planning Commission (NCPC), proposes to improve access and circulation patterns in and around Columbus Plaza for pedestrians, taxis, bicyclists, private vehicles, commercial vehicles, Metrobuses, private motor coaches, and the many tour buses with permanent stops at Union Station. The project design will include improved pedestrian safety, separation of vehicles and pedestrians at critical bottleneck locations, creation of new intersections to improve vehicular flow, the re-design of lane widths and traffic signalization patterns, and the rehabilitation of the interior of Columbus Plaza. Funding for the project is provided by the NPS and the Federal Transit Administration though DDOT who is managing the project in conjunction with NPS, USRC, AOC, and the NCPC.
