Traffic Advisory - Lane Shifts on Rhode Island Avenue NW

April 06, 2021

DC Water's contractor will remove the median area construction site located in the 300-block of Rhode Island Avenue, NW.  On or about April 12, 2021, the contractor will restore side by side travel lanes in each direction of Rhode Island Avenue, NW between 3rd Street, NW, and Florida Avenue, NW. This traffic pattern, shown in the map below, will remain in place for approximately six months. Southbound traffic on the 1800-block of 3rd Street will be allowed to make right turns only onto Rhode Island Avenue, NW. Parking restrictions remain in place.

Travel Lane Restoration and Parking Restrictions
•    Traffic will travel in two lanes in each direction between Rhode Island Avenue, NW between North Capitol Street, NW, and Florida Avenue, NW. 
•    Southbound traffic on the 1800-block of 3rd Street, NW will be allowed to make right turns only onto Rhode Island Avenue.
•    Parking restrictions remain on Rhode Island Avenue, NW between North Capitol Street, NW, and Florida Avenue, NW.

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 Anacostia River Tunnel and the First Street Tunnel, combined sewer overflows to the Anacostia River will be reduced by 98 percent. In addition to controlling combined sewer overflows, the Northeast Boundary Tunnel will reduce the chance of flooding in the areas it serves to a 7 percent chance in any given year.

Pennyfield Lock Potomac Interceptor bypass pipeline running next to C & O Canal with equipment

There is no active spill or overflow. Work to strengthen the pipe to begin soon.

Today, DC Water completed construction on a temporary bypass system as part of sewer repairs on the Potomac Interceptor near Pennyfield Lock in Potomac, Maryland. Crews turned on the pumps and successfully tested the system. With the bypass now ready, it will allow us to begin the emergency repairs inside the pipe by carrying the wastewater around the repair area.

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.

Starting the week of July 13, 2026, people who live, work or travel near the Canal Road NW entrance to Georgetown University may hear controlled blasting. This work is part of our Potomac River Tunnel Project.

When blasting happens, neighbors may hear a brief noise or feel light shaking. Drivers, cyclists, and pedestrians on Canal Road NW may also be stopped for a few minutes while we safely complete each blast.
