About the Project

This project will widen about a half-mile of Spring Street from four to six lanes from just west of Herndon Parkway to Fairfax County Parkway. The project also includes improvements along Herndon Parkway just south and north of Spring Street.

Other project components include:

  • Additional turn lanes on Spring Street and Herndon Parkway.
  • Improving sidewalks on both sides of Spring Street.
  • Adding to northbound Herndon Parkway a sidewalk as well as a cycle track, which combines the user experience of a separated path with the on-street infrastructure of a conventional bike lane.
  • Replacing the sidewalk along southbound Herndon Parkway.

Within the project limits, Spring Street averages up to 36,000 vehicles a day and Herndon Parkway averages 18,000.
