Note: In lieu of an in-person meeting that was targeted for spring 2020, you may learn more by viewing the presentation here

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:

  • A new 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.


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