(Washington, DC) – In preparation for construction associated with the DC Water Northeast Boundary Tunnel (NEBT) (dcwater.com/NEBT),  DC Water's contractor will begin staging for shaft excavation activities on 4th Street, NE at the intersection of Rhode Island Avenue, NE.

Subsequently, westbound traffic on Rhode Island Avenue will be reduced from three lanes to two lanes as it moves past the construction site. Once past the intersection at 4th Street, motorists can again utilize three travel lanes. Shaft excavation activities will begin on or about Monday, June 3, 2019.

Work hours will be 7 am to 7 pm, Monday through Friday and will take approximately 1 month to complete. Access to the businesses in the vicinity will remain open during construction activities.
