About the Project

This project will 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 between Union Mill Road and Buckleys Gate Drive averages 33,000 vehicles a day.
