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.
