This project will rehabilitate the northbound and southbound Route 123 (Chain Bridge Road) bridges over Route 7 (Leesburg Pike). The bridges were built in 1965.

The planned improvements include:

  • Repairing and resurfacing the concrete bridge decks.
  • Repairing bridge piers, abutments and bearings.
  • Painting steel bridge beams.
  • Repaving Route 123 adjacent to the bridges.

At the interchange, Route 123 averages up to 31,000 vehicles a day and Route 7 averages up to 64,000.

Estimated Costs
Preliminary Engineering - $300,000
Construction - $2.2 million

The project is being financed with federal and state State of Good Repair funds used for maintenance of structures and bridges.


The project aims to improve safety for drivers, bicyclists and pedestrians and extend the overall life of the bridges.
