This project replaced the previous weight-restricted, one-lane Hunter Mill Road (Route 674) bridge over Colvin Run that was built in 1974. The new bridge has two lanes separated by a median/splitter island. The bridge is located between the Dulles Toll Road (Route 267) and Baron Cameron Avenue (Route 606).
The project also included:
- 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 bridge averages 7,400 vehicles a day.
Preliminary Engineering - $1 million
Construction - $4.2 million
Total: $5.2 million
This project was financed with federal, state (including State of Good Repair funds used for bridges) and Fairfax County funding.
The project aimed to improve safety and traffic flow.
