The Coraopolis Bridge is a girder bridge over the back channel of the Ohio River connecting Grand Avenue on Neville Island to Ferree Street in Coraopolis, Pennsylvania. It opened in 1995 to replace a structure of historic significance. The original Pratt/Bowstring/Pennsylvania through truss spans, designed by Theodore Cooper, were formerly the (third) Sixth Street Bridge, spanning the Allegheny River, in downtown Pittsburgh, and were built in 1892 by the Union Bridge Company. They were floated downstream by the Foundation Company in 1927 rather than being demolished when the bridge was removed to enable construction of the present (fourth) Three Sisters (Pittsburgh) Sixth Street Self-anchored suspension bridge. However, by the late 1980s, the old bridge could no longer support traffic volumes and was replaced by a newer structure.

The Philadelphia & Reading Railroad Bridge carries Norfolk Southern rail lines across the Susquehanna River between Cumberland County, Pennsylvania and Harrisburg, Pennsylvania. Some of its concrete piers encase stone masonry piers from an earlier truss bridge on this site, completed in 1891 by the Philadelphia, Harrisburg and Pittsburgh Railroad, which was then acquired by the Philadelphia and Reading Railroad to connect its Harrisburg and Lurgan lines. The current structure was constructed from 1920 to 1924 by replacing the trusses with concrete arches one track at a time. The bridge has fifty-one concrete arches, three more than the nearby Rockville Bridge.

The Conestoga Creek Viaduct spans the Conestoga River east of Lancaster, Pennsylvania. The present structure, built in 1887–88, is a five-span, two-track stone arch railroad bridge. The first crossing at this location was a 1,412 feet (430 m) series of 11 wooden Town lattice trusses constructed in 1829 for the Columbia and Philadelphia Railroad, which was purchased by the Pennsylvania Railroad (PRR) and incorporated into its main line in 1857. PRR shortened the viaduct and replaced the remaining wooden trusses with iron Whipple trusses in 1863. The 1887-88 stone arch replacement was originally intended to be four tracks wide, but only half of the superstructure width was constructed, leaving an unfinished spandrel wall on the southern face. Tie rods were added in 1930 to brace the spandrel walls.
