The Virginia Department of Transportation announced a revised plan to add 11 miles of express lanes to Interstate 495, extending from the Springfield interchange to the Maryland Route 210 interchange. The project also includes a reserved right‑of‑way on the Woodrow Wilson Memorial Bridge for a future Metrorail crossing of the Potomac River.
The express‑lane addition will run alongside the existing traffic lanes along the 11‑mile corridor, creating a dedicated high‑occupancy or toll‑managed facility. VDOT officials indicated the lanes are intended to improve regional mobility and accommodate projected growth in commuter traffic. The design reserves a structural space on the bridge to allow a rail line to be installed without major alterations to the roadway later.
Fairfax County’s Board of Supervisors reviewed the updated proposal and expressed support for the combined roadway and transit component. County leaders highlighted the coordination with state transportation agencies as a step toward integrating road and rail solutions in the region. The board’s endorsement aligns with broader efforts to address congestion and expand public‑transport options in Northern Virginia.
State transportation leaders noted that the inclusion of a Metro provision reflects long‑standing discussions about extending rail service across the Potomac. While no construction timetable for the rail line was disclosed, the reserved space is intended to simplify future implementation should funding and planning for the extension advance. The express‑lane project proceeds under existing I‑495 improvement initiatives, and VDOT plans to move forward with engineering and environmental reviews in the coming months.
If approved, the expansion will represent the latest phase of an express‑lane program that has been under development for several years. The dual focus on immediate traffic relief and long‑term transit capacity aims to position the corridor for evolving travel patterns in the Washington metropolitan area.
