Belmont Ridge Road Widening in Loudoun Begins Today
Four through lanes at the Dulles Greenway set for fall 2020 completion

ASHBURN – Work begins Monday, Sept. 16 to widen about a half-mile of Belmont Ridge Road (Route 659) from two to four lanes at the Dulles Greenway (Route 267) to reduce congestion and improve safety and operations, according to the Virginia Department of Transportation.

When work is complete, drivers on Belmont Ridge Road will have two lanes in each direction at the Dulles Greenway interchange, with two-foot shoulders on both sides. On the bridge, the widening will be done entirely within the existing deck. 

Other improvements being made as part of this project include:

  • 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, financed with federal and state funding, is scheduled for completion in fall 2020. At that time, 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.

At the interchange, Belmont Ridge Road averages up to 19,000 vehicles a day and the Dulles Greenway averages up to 33,000.
