The Kenmawr Bridge Project located in Swissvale and Rankin boroughs in Allegheny County, Pennsylvania, replaced a structurally deficient single-span steel structure with a new 122-foot, two span, steel
girder bridge that crosses Norfolk Southern Railroad Company’s rail lines. The new bridge required 3 to 4 feet of vertical clearance over the existing rail lines requiring significant approach roadway, wall, and
utility reconstruction. The bridge was also lengthened for the future expansion of the PAAC’s East Busway. The construction required the installation of a temporary bridge and roadway throughout the majority of the construction to maintain traffic.

The project goal was to replace a 1908, historically eligible, one-way single-span, concrete-arch bridge. The bridge was load-restricted for 4 tons and substandard in bridge width, also having a “hump” condition in the roadway caused by the bridge. Due to poor condition, the bridge was closed to traffic in 2011, causing a several-mile detour. To replace the bridge as fast as possible, the new structure was constructed entirely of precast concrete elements and, by including the precast
design into the contract documents, the bridge was completed in eight months.
