| With certain stretches of old noise wall located adjacent to I-495, multiple lanes of the Beltway must be closed to enable safe removal. Cranes will lift and stack the old noise wall panels, and then the panels will be transported off-site. Please note that schedules could change if the weather is bad.  
 In the coming months, old noise walls will also be removed in some additional locations along the 2.5-mile 495 NEXT corridor. New, upgraded noise walls will be built to replace the old walls.  
 This work is necessary to extend the 495 Express Lanes from the current terminus near the Dulles Toll Road to the George Washington Memorial Parkway. The 495 Express Lanes extension is scheduled to open in late 2025, with overall project completion in mid-2026. |
