In Design: Route 29 Widening in Fairfax County

Note: A design public hearing was held June 10. For more information including meeting materials, click the "Public Outreach" button above.
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 and improve shared-use paths on both sides of Route 29 and provide connectivity to pedestrian/bicycle trails at the Fairfax County Parkway/West Ox Road interchange.
Estimated Costs
Preliminary Engineering: $5.7 million
Right of Way Acquisition and Utility Relocation: $26.1 million
Construction: $54.1 million
Total: $85.9 million
This project is financed with state (including Smart Scale) and local funding and the I-66 concession fee.
Route 29 within the project limits averages 33,000 vehicles a day, projected to increase to 44,000 vehicles a day by 2043.
Benefits
This project aims to reduce congestion, improve safety, operations and access management, and enhance bicyclist and pedestrian accessibility and connectivity.
