(Updated at 10:40 a.m. on 8/8/2022) Planning for a new bridge connection between Fairfax and Loudoun counties over the Dulles Toll Road has officially begun.
The Fairfax County Board of Supervisors unanimously authorized a project agreement with the Northern Virginia Transportation Authority on Tuesday (Aug. 2) for the $196 million project. The vote was conducted with no discussion.
Located at the intersection of Rock Hill Road and Davis Drive, the bridge would connect Sunrise Valley Drive over the toll road to Innovation Avenue in Loudoun County.
A new four-lane road with bicycle lanes and a sidewalk on both sides is anticipated in an effort to provide direct connections with the Innovation Center Metro Station area.
“The project will provide additional capacity across the Dulles Corridor, reduce congestion and delay on Route 28 and Centreville Road, and improve accessibility and mobility to and within the area surrounding the Innovation Center Metrorail Station,” county staff said in a memo.
Currently, the Virginia Department of Transportation is competing a feasibility study, which is expected to wrap up in early fall.
The study will include information on the conceptual design for the preferred design, cross section features, the bridge’s type, size, and exact location, as well as cost estimates and timeline.
It’s too early to know when the project will officially begin construction, but that is likely years down the line.
Over the next few years, staff will identify ways to fund the project through various pools of money. For now, the project is partially funded with NVTA’s regional funds.
Tuesday’s vote simply secures a project agreement between the NVTA and the county by allocating $20.6 million for the project.
