Motorists Traveling I-495 North to Dulles Toll Rd. West to Take New, Earlier Exit Starting Nov. 17
Portion of I-495 reduced from four to three lanes to facilitate new traffic pattern; Traffic changes necessary for 495 NEXT construction

MCLEAN, VA – Beginning on or about November 17, drivers traveling on northbound I-495 (Capital Beltway) to westbound Dulles Toll Road will take an earlier exit, rather than the existing left exit (Exit 45), which is closing to allow room for construction of a new, replacement I-495 bridge over the Dulles Toll Road ramps. This earlier exit ramp is an existing 495 North Express Lanes ramp located about one-third of a mile ahead of Exit 45, just before (slightly south of) the Dulles Toll Road bridges, which also will now be used by general purpose traffic.

To facilitate this new travel pattern, I-495 will be reduced from four to three lanes for a stretch of approximately one-half mile near the I-495 and Dulles Corridor interchange.

This roadway and ramp configuration is expected to be in place from November 2022 through late 2025. Due to this change, drivers traveling on southbound Route 123 will not be able to access westbound Dulles Toll Road from northbound I-495.

This work is part of the 495 Express Lanes Northern Extension (495 NEXT) project to 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 near the American Legion Bridge.
