Please note: The northbound Route 29 lanes between White Post Road and Paddington Lane are shifted to the left until this fall.

This project is rehabilitating the northbound Route 29 (Lee Highway) bridge over Cub Run. The bridge was originally built in 1954.

The improvements include:

  • Replacing the concrete deck and bridge rails
  • Installing steel beams
  • Adding a walkway with barrier and connecting the walkway to the existing sidewalk just north of the bridge
  • Rebuilding the concrete pedestals
  • Replacing the bridge bearings
  • Repairing cracks

The bridge averages 13,000 vehicles a day; Route 29 averages 26,000 combined northbound and southbound vehicles a day at Cub Run based on 2019 data.

Estimated Costs
Preliminary Engineering - $200,000
Construction - $3.6 million
Total - $3.8 million

The project is financed with federal, state and local funding, including State of Good Repair funds used for bridges.


This project aims to improve driver and pedestrian safety and extend the overall life of the bridge.
