Hunter Mill Road over Colvin Run Bridge Replacement Underway in Vienna
New bridge with median/splitter island and improved trail crossing scheduled for fall 2022 completion

VIENNA – Work is underway to replace the weight-restricted (ten tons) one-lane Hunter Mill Road (Route 674) bridge over Colvin Run to reduce congestion and improve operations and safety, according to the Virginia Department of Transportation.

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, and 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 based on 2019 data. 

The $5.2 million project is financed with federal, state (including State of Good Repair funds used for bridges) and Fairfax County funding. The project is scheduled for completion in fall 2022.

During construction, Hunter Mill Road bridge traffic will be controlled by flaggers as needed. Lane closures on Hunter Mill Road are allowed according to the following weekly schedule:

  • Monday through Thursday: 9 a.m. to 3:30 p.m.
  • Monday night through Thursday night: 9 p.m. to 5 a.m.
  • Friday: 9 a.m. to 2 p.m.
  • Friday night: 10 p.m. to 9 a.m.
  • Saturday night: 9 p.m. to 9 a.m.
  • Sunday night: 10 p.m. to 5 a.m.

Also during construction, intermittent closures of the trail that crosses Hunter Mill Road just south of the bridge may be needed.
