Coming Soon: Spring Street Widening in the Town of Herndon

Cost and schedule ►

Public outreach ►

Project Area

This project will widen about a quarter-mile of Spring Street from just west of Herndon Parkway to Fairfax County Parkway to allow for additional through and turn lanes. Additional turn lanes on Herndon Parkway will also be constructed at the Spring Street intersection.

The project will also connect the new Herndon Metro station to the Washington & Old Dominion Trail via a new sidewalk and eight-foot-wide cycle track along northbound Herndon Parkway. A cycle track combines the user experience of a separated path with the on-street infrastructure of a conventional bike lane.

Other pedestrian improvements include:

  • A new sidewalk along eastbound Spring Street from Sunset Park Drive to Fairfax County Parkway
  • Enhancing existing sidewalks on both sides of Spring Street
  • Replacing the sidewalk along southbound Herndon Parkway

Within the project limits, Spring Street averages about 32,000 vehicles a day and Herndon Parkway averages about 15,000.

Estimated Costs
Preliminary Engineering - $2.3 million
Right of Way Acquisition and Utility Relocation - $8 million
Construction - $12.3 million
Total: $22.6 million

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


This project aims to improves safety and operations for drivers, as well as safety, accessibility and connectivity for bicyclists and pedestrians.
