Project Limits

This project will widen Elden Street from four to six lanes between Herndon Parkway and Fairfax County Parkway (about a third of a mile) in the Town of Herndon. The total length of the project between Monroe Street and Fairfax County Parkway is about a mile.

Other improvements include:

  • Adding bike lanes from Monroe Street to Herndon Parkway and adding from Herndon Parkway to Fairfax County Parkway cycle tracks, which combine the user experience of a separated path with the on-street infrastructure of a conventional bike lane.
  • Undergrounding overhead utilities between Monroe Street and Fairfax County Parkway.
  • Replacing the culverts over Sugarland Run with a new bridge to provide better stream flow and reduce potential flooding.
  • Landscaping and planted medians where feasible.

Elden Street averages up to 30,000 vehicles a day within the project limits.

Estimated Costs
Preliminary Engineering: $6.1 million
Right of Way Acquisition and Utility Relocation: $19.9 million
Construction: $24.8 million
Total: $50.7 million

This project is being financed with federal, state and local funding, including Smart Scale and Northern Virginia Transportation Authority funding.


This project aims to reduce congestion, improve safety and enhance access to and from Fairfax County Parkway for drivers, bicyclists and pedestrians.
