The Banning Railroad Bridge is a structure that carries the Wheeling and Lake Erie Railway across the Youghiogheny River in Perry Township, Fayette County, Pennsylvania. The bridge was constructed in 1930 by the American Bridge Company as part of the major railroad to be built in Pennsylvania. Like the Speers Railroad Bridge along the same route, the structure uses a "K-truss" design that is extremely uncommon outside of the Great Plains states. Although once part of a critical connection between the Pittsburgh industrial region and the Western Maryland Railroad, today the bridge sees light traffic and is mainly used for the transportation of coal.

The Smithton Low-Level Bridge is a structure that carries Pennsylvania Route 981 across the Youghiogheny River between South Huntingdon Township and Rostraver Township, just south of Smithton, Pennsylvania. The previous structure on this site was a cantilever bridge built in 1900 to connect Smithton, which was then thriving due to its brewery, with residences on the west bank of the river; a state court ruled in favor of petitioners who demanded the creation of a bridge, but ordered that they contribute $1,200 in construction costs. Until the completion of the Smithton High-Level Bridge in 1956 (which eventually became part of busy Interstate 70), this structure was one of the most important vehicular crossings of the river. In 1986, the original bridge was replaced by a modern girder bridge.

The Smithton High-Level Bridge is a structure that crosses the Youghiogheny River between South Huntingdon Township and Rostraver Township. The bridge was opened in 1956 as one of the last links in the replacement of the old alignment of Pennsylvania Route 71 with a new four-lane freeway between Washington and the Pennsylvania Turnpike. During the same year of the bridge's completion, it was announced that the highway would become part of Interstate 70; it took on this designation in 1964 after the completion of freeway stretches in neighboring West Virginia linked PA 71 to a similar freeway in Ohio. Part of a busy truck route, the bridge is part of a highway that has been plagued by surface problems. In 1989, a crack in the superstructure, the result of a 35-year-old construction error, forced the closure of the bridge for five days, stranding truckers. The bridge was rehabilitated in 2000.
