Cost and schedule ►

Public outreach ►

This project, part of the I-66 Outside the Beltway improvements, constructed a new park and ride lot at the northeast corner of the I-66/Route 15 interchange, with access off of Heathcote Boulevard. It also established new commuter bus service from Haymarket to Rosslyn. The need for commuter parking spaces in the Haymarket area was identified by VDOT and the Virginia Department of Rail and Public Transportation in a December 2009 I-66 Transit / TDM study. 

The project included:

  • 230 parking spaces for commuters
  • Bus bays and shelters
  • Bicycle racks and lockers
  • Kiss-and-ride area
  • Parking management system
  • Efforts to limit environmental impacts including to streams and wetlands

I-66 between Haymarket and Rosslyn averages up to 190,000 vehicles a day. 

Estimated Costs
Preliminary Engineering - $930,000
Right of Way Acquisition and Utility Relocation - $995,000
Construction - $5.1 million
Total - $7.1 million

The project was financed with federal and state funding.


The lot provides a staging area for carpools using the I-66 HOV lanes, as well as transit services in the area. Other benefits include time savings for carpools and transit users, and congestion relief on I-66.
