This project will replace the weight-restricted (ten tons) one-lane Hunter Mill Road bridge over Colvin Run. The new bridge will have two lanes separated by a median/splitter island.

The project also includes:

An improved trail crossing south of the bridge
Landscaping in the median/splitter island
Abutments for a new trail bridge over Colvin Run (Fairfax County will construct the trail bridge in the future)

The existing bridge, built in 1974, averages 8,500 vehicles a day.

Estimated Costs
Preliminary Engineering - $930,000
Construction - $4.6 million
Total: $5.5 million

This project is financed with state funding (including State of Good Repair funds used for bridges) and Fairfax County funding.

Benefits

The project aims to reduce congestion and improve operations and safety.
