Drivers on Hunter Mill Road (Route 674) no longer have to yield to oncoming traffic in order to cross Colvin Run, as the new two-lane bridge opened to traffic in both directions last week on Aug. 9.
The new bridge located between the Dulles Toll Road and Baron Cameron Avenue improves traffic flow by replacing the nearly 50-year-old weight-restricted one-lane bridge that required drivers to stop if there was traffic crossing the bridge in the other direction. The bridge also includes a median/splitter island separating the two lanes to improve safety
The Hunter Mill Road over Colvin Run Bridge Replacement project, which is now complete, also includes improved trail crossing south of the bridge; landscaping in the median/splitter island; abutments for a future trail bridge over Colvin Run. The rest of the trail bridge will be constructed by Fairfax County.
The $5.2 million project was financed with federal, state (including State of Good Repair funds used for bridges) and county funding.
