Expanded Route 7 is now fully operational from Reston to Tysons

New vehicle lanes and a shared-use trail are officially open to travelers on Route 7 (Leesburg Pike) after almost five years of construction.

The Virginia Department of Transportation announced last night (Tuesday) that it has finished expanding the roadway from four to six travel lanes — three in each direction — between Riva Ridge Drive in Reston and Jarrett Valley Drive just north of the Dulles Toll Road in Tysons.

A 2-mile segment between Riva Ridge and Reston Avenue has been open to traffic since October 2022, but the additional five miles of lanes were completed well ahead of VDOT’s target date of July 31.

Work has also wrapped up on 10-foot-wide paths for pedestrians and bicyclists along both sides of Route 7, as anticipated by the Hunter Mill District Supervisor Walter Alcorn’s office. Cyclists will get a chance to try out the amenity during Alcorn’s annual Tour de Hunter Mill community bicycle ride this Sunday (May 5).

“The shared-use paths tie into those on Route 7 beyond the eastern and western limits of the project, providing a direct bicyclist/pedestrian connection from the Fairfax County Parkway Trail to Tysons,” VDOT said in a press release. “In addition, Gerry Connolly Cross County Trail users now have a new route under the Difficult Run bridge to safely cross Route 7.”

The Route 7 Corridor Improvements project redesigned intersections, including at Lewinsville Road in Wolf Trap and Baron Cameron Road in Reston, and added a pedestrian underpass for Colvin Run Mill Park, though a trail connecting to the south side of the tunnel still needs to be built by Fairfax County.

The $313.9 million project broke ground in June 2019 with the goal of improving safety, reducing traffic congestion and expanding mobility, according to VDOT, which says the affected, nearly 7-mile section of Route 7 averages 50,000 vehicles a day.

Though construction is finished, a reduced speed limit of 45 mph will remain in early May, allowing crews to remove temporary signs that were posted throughout the work zone.

“Once this work is complete, the speed limit between Reston Avenue and Wolftrap Run Road will be restored to 55 miles per hour,” VDOT said.
