The Virginia Department of Transportation is conducting an environmental study about plans to extend the I-495 Express Lanes by approximately three miles from the 495 and Dulles Toll Road interchange to the vicinity of the American Legion Bridge and Maryland line.
Virginia's 495 Express Lanes Northern Extension study, also referred to as 495 NEXT, will be developed as an independent, stand-alone project that will be closely coordinated and compatible with plans for the 495 Capital Beltway in Maryland. The full scope of improvements will be refined over the coming months.
The environmental study, which will be completed according to the requirements of the National Environmental Policy Act of 1969 (NEPA) as amended, and 23 CFR Part 771, will evaluate site-specific conditions and potential effects the proposed improvements may have on air quality, noise, neighborhoods, parks, recreation areas, historic properties, wetlands and streams, and other resources. The study began in April 2018 and is expected to be completed in Late Spring 2019.
