About the Project

This project will increase the number of lanes in each direction from one to two along Belmont Ridge Road (Route 659) over the Dulles Greenway (Route 267) without structural widening of the existing bridge to reduce traffic congestion.

The existing Belmont Ridge Road bridge over the Dulles Greenway is 60 feet wide, and provides one lane in each direction plus a left turn lane from northbound Belmont Ridge Road to the ramp to westbound Dulles Greenway. Two through lanes are proposed in each direction and a left turn lane on northbound Belmont Ridge Road to westbound Dulles Greenway, with two-foot shoulders on both sides.

North of the bridge, there will be minor pavement improvements and restriping, and retiming and other adjustments to the traffic signal at Ashburn Farm Parkway/Sycolin Road. South of the bridge, there will be more significant reconstruction of the roadway's approach and the ramps to and from eastbound Dulles Greenway.

The project will also include a new traffic signal on Belmont Ridge Road at the westbound Dulles Greenway on- and off-ramps.
