Work has begun to widen about a half-mile of Belmont Ridge Road from two lanes to four at the Dulles Greenway interchange, the Virginia Department of Transportation announced Monday.
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. The work scheduled to finish in fall of 2020.
Other elements in the project include a new traffic signal at Belmont Ridge Road and the westbound Dulles Greenway on-ramps and off-ramps, partially reconstructing the ramp from southbound Belmont Ridge to eastbound Dulles Greenway and moving the ramp entrance, repaving and restriping Belmont Ridge north and south of the bridge, and adjusting the traffic signal at Belmont Ridge Road and Sycolin Road.
Lane closures are planned from 9:30 a.m. to 3 p.m. Monday through Thursday, and Fridays from 9:30 a.m. to 2 p.m. At night, lane closures are expected from 10 p.m. to 5 a.m. Sunday through Thursday, 10 p.m. to 9 a.m. Friday, and 10 p.m. to 8 a.m. Saturday.
When the $7.5 million project is finished, 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.
