DC Water and DDOT begin restoration activities by assessing roadway in 3rd Street Tunnel
Ongoing interagency coordination key to successful response
DC Water and the District Department of Transportation (DDOT) are working closely together in the 3rd Street Tunnel to assess the condition of the damaged pavement and to plan restoration activities.
The break, which began early Monday morning, was on an 8-inch water main inside the 3rd Street Tunnel. Crews isolated the break and restored water to customers by Monday evening. DC Water located and repaired the break in the pipeline –that was installed in 1974 and services the fire hydrants in the tunnel – Tuesday night and are now working with DDOT on repair to the pavement. While there, DC Water also plans to evaluate options to further protect the water system within the tunnel to enhance reliability in the future.
Traffic patterns are expected to remain the same throughout the restoration. The northbound travel lanes in the tunnel are open. Southbound lanes of the 3rd Street Tunnel, NW, between New York Avenue and Massachusetts Avenue will remain closed until further notice. Please continue to use alternate routes.
