About the Project

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 purpose of the project (about a mile in total length) is to reduce congestion, improve safety and enhance access to and from Fairfax County Parkway for drivers, bicyclists and pedestrians. 

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.
