Greetings Neighbors!

 

As part of the DC Water Northeast Boundary Tunnel Project, we would like to update you on some of the recent activities at the Florida Avenue Construction Site. We continue to evaluate our traffic calming and pedestrian safety measures near the construction site. Recently, new signage was added around the Florida Avenue construction impact zone to improve traffic and pedestrian safety.
 
Blinking Pedestrian Crosswalk Signs
To promote additional pedestrian safety and traffic calming measures two sets of pedestrian activated blinking crosswalk signs were installed on Florida Avenue NW. One set was installed at the 2nd Street NW crosswalk and the other at the 3rd Street NW crosswalk. The signs are powered by a combination of solar and direct power.

No Thru Trucks
To discourage large hauling trucks from using streets and routes not approved by the NEBT project new No Thru Trucks Over 1 ¼ Ton signs have been posted on and near 4th Street NW:

  • On New Jersey Avenue NW heading north before the 4th Street NW intersection above the existing speed limit sign
  • On 4th Street near the New Jersey Avenue intersection
  • On 4th Street near the Q Street NW intersection

Jet Grout Plant Removal
In June, the silos located on the west side of the construction site next to the BP gas station were removed. The removal has increased the visibility of the surrounding businesses and homes.
 
The silos were a part of the jet grouting mill at the Florida Avenue NW Construction Site. Jet grouting is a process that involves injecting cement and water into the soil at a very high pressure to solidify and strengthen existing soft ground. The improved and stabilized ground allowed workers to safely excavate the drop shaft and diversion chamber, components of the diversion facility which will be connected to the Northeast Boundary Tunnel.

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.
