About the Project

The Six-Year Improvement Program approved by the Commonwealth Transportation Board in June 2014 provided $50 million to begin design, right of way and construction for Phase 1 improvements to the I-66 interchange at Route 28. 

A preliminary study identified interchange alternatives, created a concept-level operational analysis, developed cost estimates and identified key implementation constraints. 

Study results were shared with the community and stakeholders, and next steps included identifying funding.

The study considered:

  • Traffic volumes at the year 2040
  • Right-of-way impacts and property access issues for the Fairfax County Park Authority
  • Braddock and Walney roads
  • Community concerns
  • Possible phasing opportunities
