Route 9 / Route 287 Roundabout


  • The project consists of approximately one mile of roadway improvements, including a two-lane roundabout at the intersection of Route 9 and Route 287. 
  • Improvements will also include new drainage and stormwater facilities as well as relocation of some utilities. 
  • When complete, the project will significantly reduce existing traffic congestion, improve safety and provide a long-term, cost-effective solution for future maintenance.  
  • The Virginia Department of Conservation and Recreation, Virginia Department of Game and Inland Fisheries, and the US Fish and Wildlife Service determined that the project should have no impact on threatened or endangered species.

Current Status:  October 2021

  • 100% design plans and a floodplain alteration study were submitted to Loudoun County Building & Development (B&D) and the Virginia Department of Transportation (VDOT) for review and approval.
  • Loudoun County secured nutrient credits for the project, which were required to satisfy state and local stormwater runoff requirements. Each credit represents a specific amount of absorption of nutrients within a sub-watershed. Virginia’s nutrient trading program is administered by the Department of Environmental Quality (DEQ).
  • The project design team is coordinating with utilities within the project limits regarding relocation plans and needs. 
  • Right of Way (ROW) activities to begin late 2021.
