About the Project

This project will improve almost seven miles of Route 7 between Reston Avenue and Jarrett Valley Drive, including widening the road from four to six lanes, adding 10-foot wide shared-use paths on both sides and making major intersection improvements along the corridor.

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

Cost and Schedule

Preliminary Engineering: $4.3 million
Right of Way: $28.1 million
Construction: $281.5 million 
Total Estimated Cost: $313.9 million

The project was awarded to Shirley/Dewberry on July 18, 2018. The design-build schedule is as follows:

Final Design - Late Summer 2018 to Summer 2020
Right of Way - Early 2019 to Early 2021
Utility Relocation - Spring 2019 to Summer 2023
Construction - Spring 2019 to Summer 2024
Final completion by July 31, 2024

Noise Walls

VDOT conducted a preliminary noise analysis in September 2016. The study found that more than 500,000 square feet of noise barriers along the corridor were determined to be reasonable and feasible. The design-build team will perform a final noise analysis in 2019 to confirm preliminary findings. Once the final analysis is approved and prior to final design, property owners will be surveyed regarding their desire to have a noise barrier constructed. For information on VDOT's noise abatement policy, please visit the VDOT web site.

Stormwater Management

VDOT is required by law to control and treat stormwater runoff from roadways. There are two elements to treating stormwater runoff:

  • Water Quality is the reduction of pollutants from runoff.
  • Water Quantity is the reduction of the volume and speed of water released to minimize flood damage and erosion of natural stream channels.

The type, location, and size of each stormwater management facility are determined on a case-by-case basis. Stormwater management design is an iterative process and each facility will continue to evolve as roadway design advances. Please visit the VDOT web site for detailed information on stormwater management.

Right of Way

As the design of this project is finalized, property owners will be informed of the exact location of the easements during the right of way acquisition process and prior to construction on their parcels. Right of way discussions with property owners will begin during the first half of 2019. Information about right of way purchase is discussed in VDOT’s brochure, “Right of Way and Utilities: A Guide for Property Owners and Tenants.” 

Working Group

The Route 7 Widening Working Group is a collaborative effort among VDOT, the Fairfax County Department of Transportation, local board members, community representatives and other stakeholders that have helped shape the scope and design for Route 7. The group's purpose and goals include:

  • Gathering community input toward design that is sensitive to community needs
  • Developing a partnering relationship between the community and designers
  • Preparing for public meetings 
  • Fostering open communication between the design team and the public

Since 2012, the group has met on topics such as 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 storm water management.
