Temporary Traffic Signals along Hunter Mill Road in Vienna Beginning Sept. 14
Part of Colvin Run bridge project

VIENNA – Temporary traffic signals on Hunter Mill Road (Route 674) will be activated just north and south of Colvin Run around noon Wednesday, Sept. 14 as part of the Hunter Mill Road over Colvin Run bridge project, according to the Virginia Department of Transportation.

The transition points from two lanes to one on Hunter Mill Road will be moved further away from the bridge. For traffic coming from the Dulles Toll Road (Route 267), the transition to one lane will occur before the Lake Fairfax Park Maintenance entrance; for traffic coming from Baron Cameron Avenue (Route 606), the transition to one lane will occur before the residential access road located just north of the bridge. Relocating the transition points will allow the second lane of Hunter Mill Road to be constructed along and adjacent to the bridge. 

Also, three Driveway Assistance Devices (DADs) will be installed: one at the Lake Fairfax Park Maintenance entrance, one at the residential access road just south of the bridge (opposite the maintenance entrance) and one at the residential access road just north of the bridge. The DADs will allow drivers turning onto Hunter Mill Road to see which direction traffic is moving between the two temporary traffic signals.

The temporary signals and DADs, which will efficiently manage the one lane of alternating traffic in each direction on Hunter Mill Road and traffic from the side entrances, will be in place until spring 2023.

The traffic pattern changes are part of the project replacing the weight-restricted (10 tons) one-lane Hunter Mill Road bridge over Colvin Run. The bridge was originally built in 1974. 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 at a future date). The project is scheduled for completion in spring 2023.
