About the Project

This project will widen a 6.9-mile segment of Route 7 from four to six lanes between Reston Avenue and Jarrett Valley Drive, to increase capacity, decrease congestion and improve safety in conformity with the Fairfax County Comprehensive Plan.

The project will also include intersection improvements, as well as a 10-foot shared-use path on both sides of the road to increase mobility for cyclists and pedestrians

As of 2011, this section of Route 7 carried between 46,000 and 54,000 vehicles a day, and is expected to carry 73,000 to 86,000 vehicles a day by 2040.

Widening this high-volume route has been part of Fairfax County’s Comprehensive Plan for many years, and is an important improvement to the corridor that will link northern and western Fairfax with the county’s planned revitalization of the busy Tysons Corner area.

Cost and Schedule

Upon approval from the CTB sometime after the Design Public Hearing, the Route 7 Corridor Improvements Project will be split into two segments or phases.  Phase 1 runs from Jarrett Valley Drive to approximately 500 feet east of Colvin Forest Drive. Phase 2 will begin where Phase 1 leaves off (approximately 500 feet east of Colvin Forrest Drive) and end at Reston Avenue.


Total estimated cost: $265 million
Preliminary engineering: $14 million
Right of way acquisition and utility relocations: $62 million
Construction: $189 million

*Dedicated project funding is being provided through Fairfax County’s Tysons Transportation Plan on an as needed basis.

Working Group

Early in 2012, the Route 7 Widening Working Group was established with representatives from communities adjacent to the corridor, VDOT, Fairfax County, district supervisors, and the design team. The group aims to develop a partnering relationship between the community and designers, and gather input to help shape the project’s design.

Since February 2012, the team has met ten times 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 working group will continue to meet, as needed, to discuss any relevant issues related to the preliminary design. The minutes for these meetings can be found on the Fairfax County project page.
