Hunter Mill Road Bridge Replacement Begins In Reston, Vienna Area

VIENNA, VA — The Hunter Mill Road bridge over Colvin Run is being reconstructed to add two lanes of traffic on the outskirts of Reston and Vienna, according to the Virginia Department of Transportation.

The current one-lane Hunter Mill Road bridge was built in 1974 and is restricted to ten tons of weight. The replacement bridge will have two lanes separated by a median or splitter island. There will also be an improved trail crossing south of the bridge, landscaping in the median and abutments for a new trail bridge over Colvin Run. Fairfax County will construct the trail bridge in the future.

The bridge replacement project is scheduled to be completed in fall 2022, according to VDOT. Fairfax County, federal and state funding is going toward the $5.2 million project, which aims to reduce congestion and improve operations and safety.

During construction, flaggers will direct traffic as needed. Intermittent closures of the trail that crosses Hunter Mill Road south of the bridge may also be implemented.

Lane closures on Hunter Mill Road are possible during the following weekly times:

• 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.

According to 2019 data, the bridge sees an average 8,500 vehicles per day.
