Route 7 corridor improvements

Overview

The Route 7 Corridor Improvements Project was celebrated with a ribbon cutting on May 22, 2024.

Construction began in 2019 on the Route 7 Corridor Improvements Project aimed at enhancing safety, reducing congestion and expanding mobility for all users as part of Fairfax County’s Comprehensive Plan.

The project widened Route 7 from four to six lanes between Reston Avenue and Jarrett Valley Drive. As a result, Route 7 is continuously at least six lanes from Leesburg to Tysons, a stretch totaling about 20 miles.

The project also constructed shared-use paths on both sides of the entire seven-mile stretch of Route 7 between Reston Avenue and Jarrett Valley Drive. The shared-use paths tie into those on Route 7 beyond the eastern and western limits of the project, providing a direct bicyclist/pedestrian connection from the Fairfax County Parkway Trail to Tysons. The project also provided Gerry Connolly Cross County Trail users a new route under the rebuilt Difficult Run bridge to safely cross Route 7.

The project additionally:

• Constructed more than seven miles of noise barriers.
• Improved access management at 19 intersections.
• Reconstructed the Lewinsville Road intersection with the displaced left-turn lane from eastbound Route 7 to Lewinsville Road.
• Built a new pedestrian underpass at Colvin Run Mill Park.

Route 7 averages about 50,000 vehicles a day within the project limits.

This project includes federal, state (including Smart Scale), Northern Virginia Transportation Authority and Fairfax County funds. The project was awarded to Shirley/Dewberry on July 18, 2018.
