Cost and schedule ►

Public outreach ►

Project Area

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.

Other improvements 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 about 38,000 vehicles a day and Herndon Parkway averages 18,000 based on 2019 data.

Total: $20.2 million

This project is financed with federal, state (including Smart Scale and Revenue Sharing funding) and local funding.
