495 Southside Express Lanes Study Update

The Virginia Department of Transportation (VDOT) is continuing its work on an Environmental Assessment evaluating options that would provide additional travel choices, reduce congestion, improve travel reliability and improve safety on the southern section of I-495 (Capital Beltway). As the only remaining section of the Beltway without express lanes, VDOT’s study is looking at alternatives that would extend the express lanes in this area. 


Travelers on this section of I-495 are facing increasing congestion and challenges now. VDOT's study is focused on solutions that would provide relief, promote transit and new travel choices, and be flexible to not preclude future rail improvements.


VDOT is conducting its study in cooperation with the Federal Highway Administration (FHWA), Maryland Department of Transportation State Highway Administration (MDOT SHA), Virginia Department of Rail and Public Transportation (DRPT), and other federal, state, regional, and local agencies in Virginia and Maryland.


While work continues on the study, with a focus on finding the best possible options through traffic and operational analyses, VDOT encourages the public to sign up to receive study updates and notices. The study team will hold more public and community meetings later this year, followed by public hearings when the Environmental Assessment is released for review and comment.

Sign Up and Stay Engaged

Public involvement is a critical element in the development and delivery of transportation projects.

Recap of Public Meetings in September 2023

VDOT held public information meetings in September 2023 to provide updates on the progress of the study, present preliminary alternative concepts, and gather public input to inform the range of alternatives to be carried forward in the study. The meeting materials, including the virtual meeting recording, presentation, brochure, and public comment summary report, are available on the study webpage.
