About the Project

This project will reconstruct and widen 1.5 miles of Route 29 (Lee Highway) from four to six lanes between Union Mill Road and Buckleys Gate Drive. It will relieve a major bottleneck during AM and PM peak hours, with lengthy backups occurring in particular at the signal for Stringfellow/Clifton roads (Route 645).

The project will also correct vertical alignment to improve sight distance, add/improve bicycle and pedestrian facilities on both sides of Route 29 and provide connectivity to pedestrian/bicycle trails at the Fairfax County Parkway/West Ox Road interchange. Multiple public outreach efforts are planned.

Route 29 within the project limits averages 33,000 vehicles a day.
