The National Park Service is making improvements to roads, multi-use trails and crosswalks around the National Mall. The work will improve accessibility and safety and help the NPS implement our paved trails plan by making new connections and enhancing existing pedestrian and bicycle travel routes.

Roadwork

Drivers should expect construction on several roads around the National Mall. The work is scheduled to happen mostly during off-peak hours. This means drivers should expect intermittent lane closures. The work will happen on:
  • Rock Creek and Potomac Parkway between the Virginia Avenue NW and Parkway Drive NW.
  • Eastbound Independence Avenue SW between 23rd Street SW and 15th Street SW.

  • 17th Street between Independence Avenue SW and Constitution Avenue NW.
