In Design: Elden Street Widening and Underground Utilities Duct Bank in the Town of Herndon

Underground Utilities Duct Bank

This project will construct an underground utilities duct bank to replace the existing overhead utilities along about a mile of Elden Street between Monroe Street and Fairfax County Parkway. Construction on the duct bank is scheduled to begin in late 2024.

Elden Street Widening

This project will widen about a third of a mile of Elden Street from four lanes to six between Herndon Parkway and Fairfax County Parkway.

Other improvements along Elden Street include:

• Adding bike lanes from Monroe Street to Herndon Parkway
• Adding cycle tracks from Herndon Parkway to Fairfax County Parkway that combine the user experience of a separated path with the on-street infrastructure of a conventional bike lane
• Replacing the box culvert over Sugarland Run with a new bridge to provide better stream flow and reduce potential flooding
• Pedestrian enhancements
• Landscaping and planted medians where feasible

Construction on the Elden Street Widening improvements is scheduled to begin in mid-2027.

Elden Street averages about 25,000 vehicles a day within the project limits.

Estimated Costs
Preliminary Engineering: $6.9 million
Right of Way Acquisition and Utility Relocation: $13.3 million
