Long-Term Closure of the 14th Street Ramp to Maine Avenue SW – Anticipated Start May 30, 2026 Maine Avenue SW Traffic Shift – Anticipated Start May 30, 2026
(WASHINGTON, DC) — The District Department of Transportation (DDOT), in coordination with the Virginia Passenger Rail Authority (VPRA), will implement changes to the traffic patterns on and near Maine Avenue SW as part of the Long Bridge Project. These changes are anticipated to begin as early as May 30, 2026. The changes will include a temporary closure of the northbound 14th Street ramp to Maine Avenue SW, anticipated to last from May 30, 2026, through project completion in 2030. In addition, a temporary traffic pattern shift on Maine Avenue SW between Ohio Drive and the Salamander Hotel entrance is anticipated from May 30, 2026, through early 2028.
Northbound 14th Street Ramp Closure Detour Route:
- Continue North on 14th Street SW.
- Turn right on Independence Avenue SW.
- Turn right onto Southbound 12th Street SW.
- Reconnect with Eastbound Maine Avenue SW.
Maine Avenue SW Traffic Shift:
- Two travel lanes will remain open in the Westbound direction.
- One travel lane will remain open in the Eastbound direction.
- Pedestrian access will be maintained in this area. Please follow detour signs.
Please watch the project video for additional details regarding the traffic shift and access changes. Additional information will be shared once dates are finalized for the 14th Street ramp closure and the Maine Avenue traffic pattern shift. Drivers are encouraged to allow additional travel time and follow all posted detour and traffic-control signage in the area. Traffic-control devices will be in place to safely guide motorists, pedestrians, and other roadway users around the work zone.

  Long Bridge Project
The Virginia Passenger Rail Authority’s Long Bridge Project is a 1.8-mile rail improvement that will relieve one of the biggest rail bottlenecks on the East Coast. The project will improve reliability and expand capacity for both passenger and freight trains traveling between Virginia and Washington, DC. The project will create a continuous four-track corridor between the Long Bridge Aquatic Center in Arlington County, Virginia, and L’Enfant Plaza in Washington, DC. It includes five new rail bridges and two new pedestrian/ bicycle bridges. A new two-track rail bridge will be built over the Potomac River next to the existing two-track Long Bridge, along with a new bike and pedestrian bridge connecting Long Bridge Park and the Mount Vernon Trail in Arlington to East Potomac Park in DC.
The Long Bridge Project is one of the Virginia Passenger Rail Authority’s many rail projects across the Commonwealth. Learn more at: https://vapassengerrailauthority.org/.
