Subject: NEBT: Rhode Island Ave. NW - Instrument Installation
Greetings Neighbors.
DC Water’s contractor continues to
install extensometers along Rhode Island Avenue NW from North Capitol
Street NW to R Street NW in preparation for the arrival of the tunnel
boring machine. Extensometers are deep borehole monitors installed to
measure any soil displacement during the construction of the tunnel.
The contractor is currently installing extensometers along Rhode Island
Ave. NW between 3rd Street and Florida Avenue NW. It takes
approximately 3 to 4 days for each instrument to be installed. A geotechnical
drill rig (pictured) is being used for the installation process and is
occupying one lane of Rhode Island Avenue NW causing traffic to go
around the construction. Residents will experience parking restrictions
and lane changes during work hours. Parking restrictions will be
removed each day at 3:30 pm.
Work is taking place between 9:30 AM to 3:30 PM, weather permitting and
is anticipated to be completed in mid-April.

Project
Details
The Northeast Boundary Tunnel (NEBT) 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. Once the
NEBT is connected to the other Clean Rivers tunnels, combined sewer
overflows to the Anacostia River will be reduced by 98 percent. The
NEBT will also reduce the chance of flooding in the areas it serves
from approximately 50 to 7 percent in any given year.
