The Virginia Department of Transportation announced Monday that work has begun to expand a half-mile of Belmont Ridge Road/Route 659 in Ashburn from two to four lanes at the Dulles Greenway interchange.
The congestion relief and safety project is slated for completion in fall 2020.
The project includes:
-A new traffic signal – including a flashing yellow arrow – at Belmont Ridge Road and the westbound Dulles Greenway on- and off-ramps.
-Partially reconstructing the ramp from southbound Belmont Ridge Road to the eastbound Dulles Greenway and moving the ramp entrance slightly south of its current location.
-Repaving and restriping Belmont Ridge Road just north and just south of the bridge.
-Retiming and adjusting the traffic signal at Belmont Ridge Road and Sycolin Road.
Drivers can expect lane closures according to the following weekly schedule:
-Monday through Thursday: 9:30 a.m. to 3 p.m.
-Friday: 9:30 a.m. to 2 p.m.
-Sunday night through Thursday night: 10 p.m. to 5 a.m.
-Friday night: 10 p.m. to 9 a.m.
·Saturday night: 10 p.m. to 8 a.m.
The $7.5 million project is being financed with federal and state funding. Once complete, VDOT officials noted, the northernmost five miles of Belmont Ridge Road will have four through lanes between Truro Parish Road and Riverside Parkway. The widening of Belmont Ridge Road from two to four lanes between Hay Road and Gloucester Parkway was completed in December.
Belmont Ridge Road near the interchange averages up to 19,000 vehicles a day and the Dulles Greenway averages up to 33,000.
