Traffic Changes

New Exit Ramp for I-495 North Exit to Dulles Toll Road

Reminder: Motorists traveling on northbound I-495 heading for westbound Dulles Toll Road must take a new, earlier exit. The new exit ramp is located about one-third of a mile ahead of the old, closed Exit 45. To facilitate this new traffic pattern, I-495 has been reduced from four to three lanes for approximately one-half mile near the Dulles Corridor interchange. Learn more about the traffic change here.

George Washington Memorial Parkway West at I-495

Reminder: The ramp from westbound George Washington Memorial Parkway to southbound I-495 (Capital Beltway) was reduced from two lanes to one lane to make room for a construction vehicle haul route that will be separated from traffic by a physical barrier. This traffic change will be in effect throughout construction on the 495 NEXT project. Learn more about the traffic change here.

Project Background

The I-495 Express Lanes Northern Extension (495 NEXT) project will extend the existing 495 Express Lanes north by two-and-a-half miles from the Dulles Corridor interchange to the George Washington Memorial Parkway interchange in the vicinity of the American Legion Bridge. The project will provide new and improved connections at the Dulles Corridor and George Washington Memorial Parkway.

Other 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, environmental improvements introducing stormwater management facilities and funding of restoration at Scotts Run stream, and dedicated funding to support transit improvements in the corridor including new bus service over the American Legion Bridge.

495 NEXT is a public-private partnership project between the Commonwealth of Virginia and Transurban, operator of the existing 495 Express Lanes. Lane Construction is the design-build contractor for the project. The new extended lanes are scheduled to open in 2025.
