Westbound M Street Lane Closures Through September

Through Sept. 15 there will be one westbound lane of M Street closed near the Key Bridge between the hours of 9 p.m. and 5 a.m. as DC Water crews replace critical infrastructure. Work days are Monday through Friday.

The work on M Street between Potomac Street and the Key Bridge is part of the Large Valve Replacements Project. The project will "improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system," according to the DC Water website.

"Excavation operations will result in extreme noise during abbreviated periods. Please anticipate traffic stops and delays within the vicinity until the project is complete," advised a notice from the Georgetown Business Improvement District.
