Change is coming to one of the major highways through our county.

The Commonwealth of Virginia continues the process of transforming 22.5 miles of I-66 outside the Beltway, from I-495 to Haymarket. Initial construction in rights of way is expected to begin by the end of this calendar year. The approximately $3 billion I-66 project is a public-private partnership between the Virginia Department of Transportation (VDOT), the state Department of Rail and Public Transportation and a private entity (I-66 Express Mobility Partner). VDOT presented an update to the Board of Supervisors on Oct. 10.

Community input has been a critical part of the project. This year, 140 homeowners associations have been contacted and more than 40 briefings have been held with homeowners associations, community organizations and other key stakeholders.

All residents will have the opportunity to get more information and provide input on the project designs during meetings Nov. 13-16.


What Are The Improvements?

This project is designed to improve safety and relieve the congestion on I-66, moving 2,000 to 4,000 more people per hour. Improvements include:

  • Two Express Lanes in each direction from I-495 to Gainesville
  • Three general purpose lanes in each direction
  • HOV and transit access to Express Lanes
  • Median space reserved for future transit
  • Add more than 4,000 park-and-ride options with access to Express Lanes
  • Bike-pedestrian trail integrated with existing and planned trails
  • Fund new buses and transit routes

Specific areas will see significant changes, too. For example, here’s a diagram of the proposed changes to the I-66/Route 28 interchange:
