Traffic Advisory: Northeast Boundary Tunnel Project Traffic and Parking Restrictions on Rhode Island Avenue, NW

June 04, 2019

(Washington, DC) – DC Water's contractor will begin jet grouting work at the intersection of First Street and Rhode Island Avenue, NW, as a continuation of work associated with the Northeast Boundary Tunnel Project. The contractor will install jet grout columns on the north side of the intersection at First Street and Rhode Island Avenue, NW. One method of stabilizing the soil on the Northeast Boundary Tunnel Project is a process known as jet grouting, a method of ground improvement that involves injecting cement and water into the soil at very high pressures to solidify and strengthen the ground.  The improved ground will allow safe excavation in the stabilized ground to connect the existing First Street Tunnel with the new Northeast Boundary Tunnel.
 
Work is expected to begin the week of June 10, 2019,  from 7 AM – 7 PM, Monday – Friday, and will continue for approximately eight (8) months (weather permitting).

Travel Restrictions 

  • Rhode Island Avenue, NW between 2nd Street, NW and North Capitol Street, NW will be reduced to two lanes of traffic in each direction.
  • First Street NW between Thomas Street and Rhode Island Avenue will be closed to northbound traffic. Detour signs will be in place to direct traffic to 2nd Street, NW.
  • Parking Restrictions
  • Parking will be restricted on the north and south sides of Rhode Island Avenue, NW between North Capitol Street and 2nd Street, NW. 
  • There will also be restrictions to parking on both sides of First Street, NW between Thomas Street and Rhode Island Avenue, NW.

Pedestrian Detours

  • The north side crosswalk at the intersection of First Street and Rhode Island Avenue, NW will be closed.
  • The eastbound crosswalk on Rhode Island Avenue, NW at First Street will be closed. Detour signs will be posted to direct pedestrians.

Project Details
The Northeast Boundary Tunnel is the largest component of the Clean Rivers Project and will start south of RFK Stadium and extend north to Rhode Island Avenue, NE, and west to 6th Street, NW. When complete, the approximately five-mile long tunnel will significantly reduce chronic flooding in areas it serves, as well as reduce the amount of combined sewer overflows into the Anacostia River.

Pumping capacity remains a challenge, due to ongoing maintenance and operational issues. An overflow occurred late Monday night, when two pumps – clogged with non-disposable wipes – were taken out of service for cleaning and maintenance. During a period of high flow, the volume of wastewater temporarily exceeded pumping capacity resulting in the overflow.

The overflow did not enter the Potomac River and was contained on-site by an earthen dam and a trench system that captured and redirected the wastewater back into the sewer system.

DC Water and its contractors continue working around the clock, to operate, clean and maintain bypass pumps that divert wastewater around the damaged section of the Potomac Interceptor and return flows into the system further downstream. Despite these efforts, a significant overflow occurred late Sunday.

DC Water is taking emergency measures with the immediate and ongoing closure of all northbound lanes of 14th Street between L Street NW and Thomas Circle, due to the imminent risk of collapse posed by an abandoned, century-old, brick-lined sewer tunnel beneath the roadway.
