The I-495 Express Lanes Northern Extension (495 NEXT) project is a public-private partnership between the Commonwealth of Virginia and Transurban that involves extending the 495 Express Lanes north by two-and-a-half miles from the Dulles Corridor to the George Washington Memorial Parkway interchanges near the American Legion Bridge. This important initiative will provide congestion relief, add travel choices, improve travel reliability and enhance safety on a vital corridor in Northern Virginia and the larger region. 495 NEXT will provide new and improved express lanes connections at the Dulles Corridor and George Washington Memorial Parkway interchanges.
Other 495 NEXT project benefits include four miles of new bicycle and pedestrian connections including a shared-use path parallel to I-495 from Lewinsville Road to near Live Oak Drive, replacement or rehabilitation of seven bridges with pedestrian accommodations, replacement of nine existing noise walls and construction of a new noise wall along Live Oak Drive in the vicinity of the George Washington Memorial Parkway interchange, environmental improvements introducing stormwater management facilities and funding restoration of the stream at Scotts Run, and dedicated funding to support transit improvements in the corridor including new bus service over the American Legion Bridge.
The 495 NEXT Interactive Map provides information about the project’s design and what is being constructed. Design elements and features are color coded according to the map legend. 495 NEXT is a design-build project, and details shown on this interactive map are subject to change and may be updated as the project's design is finalized.
Construction kicked off on VDOT's 495 NEXT project in March 2022, along with final project design. The extended 495 Express Lanes are expected to open in late 2025, with the project completed in 2026.

The Virginia Department of Rail and Public Transportation (DRPT) and the Maryland Department of Transportation Maryland Transit Administration (MDOT MTA) conducted the I-495 American Legion Bridge (ALB) Transit/Transportation Demand Management (TDM) study to identify a range of current and future multimodal solutions that can be implemented to reduce congestion, improve trip reliability and regional connections, and enhance existing and planned multimodal mobility and connectivity for travel across the American Legion Bridge, focusing on the segment of I-495 between I-95 (Maryland) and I-395/95 (Virginia).
