Washington – The National Park Service (NPS) is undertaking a number of projects over the next year to improve accessibility and safety and create seamless connections across the National Mall. This work will rehabilitate trails and roads, and it will feature new and enhanced infrastructure for park visitors walking and bicycling.

  • Replace curb ramps and crosswalk push buttons to meet modern accessibility standards. 
  • In coordination with the District Department of Transportation, extend the 15th Street NW Cycletrack (a two-way protected bike lane) between Pennsylvania Avenue NW and East Basin Drive SW.
  • Improve the volleyball courts on Parkway Drive by repaving existing footpaths, installing new poles, netting, and a drinking fountain and planting new sod and trees. Scheduled completion around Labor Day 2021. 
  • Enlarge and enhance the green space at the Belvedere, the historic end of Constitution Avenue NW. 
  • Plant new trees along the Rock Creek Trail along the Potomac River between Virginia Avenue NW and Parkway Drive NW. 

The NPS strives to lead the region in providing exceptional outdoor experiences. We seamlessly link richly diverse places of natural and historic significance in the national capital area while providing safe and enjoyable experiences for people to walk, run, bike and have fun with friends and family.
