Under Construction: I-66 at Route 28 in Fairfax County

Note: This project is being constructed as part of the Transform 66 Outside the Beltway Improvements.

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

Benefits 

This project aims to reduce congestion and associated air quality impacts, improve safety and operations and enhance bicycle and pedestrian accessibility.
