Traffic Advisory: Northeast Boundary Tunnel Shaft Excavation Work to Begin at 4th Street, NE

June 05, 2019

(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. This will require the current work site on 4th Street to be expanded into one lane on Rhode Island Avenue. 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.

Travel Restrictions:

Westbound Rhode Island Avenue, NE - traffic will merge into two-lanes of travel left around the 4th Street, NE construction and then return to three-lane travel immediately past the intersection.

Pedestrian Impacts:

The pedestrian crosswalk across 4th Street, NE at the Rhode Island Avenue, NE intersection will be closed for approximately 1 month. Detour signs will guide pedestrians to safely cross Rhode Island Avenue and the southern intersection of 4th Street.

Safety Information

  • As a result of the construction work, commuters may experience congestion within the 250-foot designated work area. Please do not tailgate, keep a safe distance, and don’t drive distracted.
