Jacks Run Bridge

This historic bridge is located in the Borough of Bellevue, in Allegheny County, Pennsylvania. Bellevue is an older community just northeast of downtown Pittsburgh and the bridge on Lincoln Avenue carries vehicles and pedestrians over Jacks Run, a deep ravine that cuts through the neighborhood.

This project involved the rehabilitation of an open spandrel concrete deck arch, built in 1926. The deck arch included 14 approach spans, 15 feet to 20 feet long, and a 320-foot-long main span – for a total length of 590 feet. The deck arch supports a two-lane roadway with 7-foot shoulders and two sidewalks.

The bridge replacement included expansion dams, six concrete floorbeams, four concrete columns and utilized galvanic anode corrosion protection. ms consultants replaced the drainage system and bearings and installed decorative bridge lighting for approximately 200 feet on either side of the bridge.

To maintain some connectivity for the neighborhood during construction, the bridge was closed to vehicles but pedestrian traffic was maintained at all times.

This was an American Recovery and Reinvestment Act of 2009 (ARRA) funded project.
