About the Project
This project is replacing the structurally deficient Lee Highway (Route 29) bridge over Little Rocky Run and widening it to three lanes in each direction. It includes a ten-foot trail on the south side of the bridge, and a five-foot sidewalk to the north.
The old bridge was built in 1932 and was in overall poor condition, with a sufficiency rating of 20.9 on a scale of 0 (poor) to 100 (very good). The sufficiency ratings developed by the Federal Highway Administration serve as a prioritization tool to allocate funds. The rating considers adequacy, whether the bridge is functionally obsolete, and the service level provided to the public.
The bridge carries approximately 36,000 vehicles per day.
During construction, drivers can expect some off-peak lane closures and traffic shifts from 9:30 a.m. to 3:30 p.m. and 10 p.m. to 5 a.m. Monday to Thursday; 9:30 a.m. to 2 p.m. Friday; and overnight on weekends as crews replace the bridge. All work is weather permitting.
