About I-66 Corridor Improvements

Work is underway to transform Northern Virginia’s Interstate 66 into a multi-modal corridor that moves traffic and people quicker and in a more reliable way. VDOT and the Virginia Department of Rail and Public Transportation (DRPT) are actively evaluating improvements that would provide added capacity, and new options with more predictable travel times. Under the proposed plan, I-66 would be improved to provide:

  • Three regular lanes in each direction
  • Two express lanes in each direction
  • High-frequency bus service with predictable travel times
  • Direct access between the express lanes and new or expanded commuter lots

In July 2014, the team kicked off a year-and-a-half of environmental study and community involvement. By the end of 2016, the team is working to complete environmental work, identify funding sources, receive federal approval and begin construction in 2017.
