Transforming I-66 Outside the Beltway

Work is underway to transform Northern Virginia’s Interstate 66 into a multimodal corridor that moves more people, provides reliable trips and offers new travel options.

The $2.3 billion I-66 Outside the Beltway Project is a public-private partnership between the Virginia Department of Transportation (VDOT), the Department of Rail and Public Transportation (DRPT) and private partner, I-66 Express Mobility Partners, a consortium of Cintra, Meridiam, Ferrovial Agroman US and Allan Myers VA Inc.

The I-66 Outside the Beltway Project will include:

  • 22.5 miles of new express lanes alongside three regular lanes from I-495 to University Boulevard in Gainesville
  • Express lanes will be dynamically tolled to manage demand for the lanes and provide a reliable, faster trip – available to drivers who choose to pay a toll, and for free to vehicles with three or more people
  • New and improved bus service and transit routes
  • New and expanded park and ride lots providing convenient access to the express lanes and more than 4,000 new park and ride spaces
  • Interchange improvements to enhance safety and reduce congestion, including auxiliary lanes between interchanges, where needed
