Named the Anacostia River Tunnel, this will be 7 m-diameter and 3,810 m-long beneath the Anacostia River. It begins at Poplar Point and ends near RFK Stadium. Construction will start at the north and work south, connecting to the Blue Plains Tunnel in 2017. The contract also includes six shafts with a depth of approximately 30 m and three diversion structures. The first tunnel portion of the Clean Rivers Project is already underway. For more click here.
