Project Details

The Northeast Boundary Tunnel is the largest component of the Clean Rivers Project. It begins south of RFK Stadium and will extend north to Rhode Island Avenue, NE and west to 6th Street, NW. When complete, the approximately five-mile-long tunnel will significantly reduce chronic flooding in areas it serves, as well as reduce the amount of combined sewer overflows into the Anacostia River.
