I-66 Corridor Improvements

The Virginia Department of Transportation (VDOT), in coordination with the Virginia Department of Rail and Public Transportation (DRPT), will upgrade I-66 outside the Beltway to include:

  • Three regular lanes in each direction;
  • Two express lanes in each direction from I-495 (the Capital Beltway) to Gainesville (University Boulevard);
  • New and expanded transit service and park-and-ride lots; and
  • Interchange improvements to enhance safety and reduce congestion, including auxiliary lanes between interchanges, where needed.

The improvements will provide new travel choices, while enhancing transportation safety and travel reliability.

How Express Lanes Work

The proposed express lanes would be dynamically-priced toll lanes that are designed to provide a reliable, faster trip. Drivers traveling with three or more occupants would be considered high occupancy vehicles, and could use the express lanes for free at any time.

Transit Options: A Key Priority

A transit and transportation demand management (TDM) planning process is underway by VDOT and DRPT in coordination with the development of the Transform 66 Outside the Beltway Project. The transit/TDM recommendations, which are integral to the overall Project, are focused on the following objectives:

  • Efficient use of public transportation infrastructure and services
  • Reduction in congestion
  • Increase in the availability and reliability of travel choices
  • Improvement in the attractiveness, reliability and quality of transit
  • Increase in park-and-ride space supply, convenience and availability
  • Effective use of the region’s developed and emerging managed lanes network, including I-66, I-495, I-395 and I-95 through Integrated Corridor Management (ICM)

For additional information, please see the transit exhibits from the Public Information Meetings that were held in January and February 2015.
