Press Release: 495 Express Lanes Extension
FAIRFAX, VA — The 495 Express Lanes Extension (the Extension) remains on schedule to open this Saturday, Nov. 22, weather permitting. The two-and-a-half-mile extension of new 495 Express Lanes spanning from near the Dulles Corridor Interchange to just before the American Legion Bridge and new connecting ramps are scheduled to be fully open and operational by mid-morning Saturday.
The opening of the Extension will bring the most significant change to the Beltway in Virginia since the opening of the original 495 Express Lanes in November 2012. Drivers should use caution and expect new travel patterns, as traffic becomes acclimated with the new lanes and ramps.
