The Beltway has been reduced from four to three lanes for approximately a half mile near the Dulles Corridor interchange to help facilitate the change.
George Washington Memorial Parkway West at I-495
The ramp from westbound George Washington Memorial Parkway to southbound Beltway has been 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.
