NEBT: Traffic & Parking Restrictions at First Street and Rhode Island Avenue NW











Northeast Boundary Tunnel Project
First Street NW Pumping Station Construction Site Newsletter
July 19, 2019






Greetings,




The First Street NW Pumping Station Construction Site jet grout work was delayed due to the additional coordination with the District Department of Transportation on the traffic light infrastructure. DC Water's contractor is rebuilding a collapsed electrical conduit under Rhode Island Avenue, NW. Once that work is complete, the existing signals in the middle of Rhode Island Avenue at First Street, NW will be removed, traffic will be shifted, and the contractor will mobilize for jet grout work to begin at the intersection of Rhode Island Avenue and First Street, NW. This work is expected to begin the week of July 22, 2019.

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 July 22, 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.

Project Details
The Northeast Boundary Tunnel is the largest component of the Clean Rivers Project. It begins south of RFK Stadium and will 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 by 98%.
