About the Project

This project aims to reduce congestion and improve safety by widening the Fairfax County Parkway (Route 286) from four to six lanes between Route 29 (Lee Highway) and Route 123 (Ox Road).

The project also includes building an interchange that will consolidate Popes Head Road and the future Shirley Gate Road extension.

In addition to the roadway widening, improvements will be made to the existing Fairfax County Parkway Trail. Where there is no trail currently, a new shared-use path will be constructed to make the trail continuous within the project limits.

The project will be implemented as part of a phased approach based on funding availability:

  • Phase 1: Popes Head Road and Shirley Gate Road interchange
  • Phase 2: Fairfax County Parkway widening
