This project involves replacing or rehabilitating a single span, concrete slab bridge located in Folcroft Borough and Darby Township.
The existing bridge, built in 1932, is a 25-foot single-span bridge with a 16’-11” clear span. The bridge superstructure consists of a reinforced concrete slab with reinforced concrete parapets exhibiting heavy cracking, efflorescence and spalling throughout. The bridge substructure consists of reinforced concrete abutments and U-shaped wing walls exhibiting severe spalling, moderate to heavy efflorescence and cracking throughout. The bridge is considered “poor condition,” limiting its load carrying capacity to a maximum of 18 tons except combination loads of 24 tons. The bridge will be replaced with a 28-foot single-span composite pre-stressed concrete adjacent plank beam bridge. The new structure will have a wider clear span of 17’-9” locating the proposed abutments outside of the existing waterway. The new bridge will have an increased hydraulic opening which will decrease the water surface elevation of the 100-year flood. Tribbett Avenue will be reconstructed to provide one 11-foot wide travel lane in each direction. A 4-foot wide shoulder will be provided on the upstream side of the bridge and a 2-foot wide shoulder on the downstream side.
