Coming Soon: Spring Street Widening in the Town of Herndon

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.
