The Potomac River Tunnel project is a landmark initiative under the Clean Rivers Project. The project aims to construct a nearly 5.5 miles tunnel beneath the Potomac River with 2 different TBM, serving as a critical infrastructure element to control combined sewer overflows. This will significantly enhance the water quality of the Potomac and Anacostia Rivers and Rock Creek while bolstering the sewer system’s capacity.
