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).

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.
