St. Andrews ChapelAbout the Project

The Route 7 Corridor Improvements Project will improve 6.9 miles of Route 7 between Reston Avenue and Jarrett Valley Drive. Some of the proposed work includes:

  • Widening of Route 7 from four to six lanes
  • Intersection improvements
  • Adding 10-foot wide shared-use paths on both sides of the road 

These improvements will decrease congestion, increase capacity, improve safety, and expand mobility for cyclists and pedestrians - all in conformity with Fairfax County’s Comprehensive Plan.

Working Group

The Route 7 Widening Working Group is a collaborative effort that involves VDOT, the Fairfax County Department of Transportation, district supervisors' staff, other agencies, and community representatives regarding the scope and design of Route 7.  

Purpose and goals of the working group include:

  • Gathering community input prior to re-initiating project design work to obtain a design that is sensitive to community needs
  • Developing a partnering relationship between the community and the designers
  • Preparing for public meetings, including a citizens' information meeting and a public hearing
  • Fostering open communication between the design team and the public

The working group and design team have met on more than 10 occasions and discussed topics including environmental impacts, land development along the corridor, bicycle and pedestrian needs, innovative intersection designs, high occupancy vehicle (HOV) lane feasibility, mass transit and bus service, and preliminary storm water management needs. The minutes for these meetings can be found on the Fairfax County project page.
