Weekend Road and Rail: Beltway and I-66 stops, Metro Red Line shutdown

More stops are planned for the Capital Beltway and Interstate 66, the I-295/DC-295 Corridor Project, Purple Line work and paving in Maryland. Metro work is scheduled on five lines, with a Red Line shutdown.

Here’s what you need to know this weekend.



The District Department of Transportation will have continued maintenance on DC-295 on the bridge over Nicholson Street, which is just south of Pennsylvania Avenue SE. This operation will begin Friday and continue through May 28, weather permitting.

Here is what motorists can expect:

  • Two right lane closed on the bridge, south of Pennsylvania Avenue, which means two left lanes will be open for through traffic.
  • Exit ramps to Pennsylvania Avenue will remain open during the daytime hours.
  • Closures will remain in place 24 hours for the entire week.
  • Additional lane closures will be implemented overnight to facilitate bridge resurfacing work, leaving one lane open for traffic.
  • Heavy congestion is expected during this operation, and travelers are advised to seek alternative routes.

There continues to be construction activities along I-295/DC 295 and nearby local roads with the ongoing corridor project. Motorists can expect lane and ramp closures along I-295/DC-295, South Capitol Street, the Suitland Parkway, Firth Sterling Avenue SE, Howard Road SE, Potomac Avenue SE/SW, Half Street and more.

On Friday night, westbound Howard Road SE will be closed and detoured between the Anacostia Metro station and the WMATA Parking Garage from 9 p.m. through 7 p.m. on Saturday.
