The Chesapeake & Delaware Canal is a 14-mile (22.5 km)-long, 450-foot (137.2 m)-wide and 35-foot (10.7 m)-deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States.
The Delaware River Joint Toll Bridge Commission (DRJTBC) is a bistate, public agency that maintains and operates river crossings connecting the U.S. states of Pennsylvania and New Jersey. The agency's jurisdiction stretches roughly 140 miles (230 km) along the Delaware River from Philadelphia and Bucks County in southeast Pennsylvania and then north through the Lehigh Valley and to Pennsylvania-New York state border.
The Main Line of Public Works was a package of legislation passed by the Commonwealth of Pennsylvania in 1826 to establish a means of transporting freight between Philadelphia and Pittsburgh. It funded the construction of various long-proposed canal and road projects, mostly in southern Pennsylvania, that became a canal system and later added railroads. Built between 1826 and 1834, it established the Pennsylvania Canal System and the Allegheny Portage Railroad.
Philadelphia and Columbia Railroad (P&CR) (1834) was one of the earliest commercial railroads in the United States, running 82 miles (132 km) from Philadelphia to Columbia, Pennsylvania, it was built by the Pennsylvania Canal Commission in lieu of a canal from Columbia to Philadelphia; in 1857 it became part of the Pennsylvania Railroad. It is currently owned and operated by Amtrak as its electrified Keystone Corridor. The Philadelphia and Columbia Railroad's western terminus was located near the former ferry site known as Wright's Ferry, in the town once of that name, but now Columbia in Lancaster County. There the P&CR met with the Pennsylvania Canal—navigations and improvements on the Susquehanna River east bank approximately 30 miles (48.3 km) south of Harrisburg, Pennsylvania. Most of its right-of-way was obtained by the actions of the Pennsylvania Canal Commission which operated the railroad under the various enabling acts of the Pennsylvania legislature known as the Main Line of Public Works in support of a far sighted plan to link the whole state by canals. With an engineering study reporting back a finding that obtaining sufficient waters to flood the intended 80+ mile canal from Philadelphia to Columbia, the Canal Commission and legislature authorized the railway on the right of way intended for the canal.
Poquessing Creek is a 10.3-mile-long (16.6 km) creek, a right tributary of the Delaware River, that forms the boundary between Philadelphia and Bensalem Township, which borders it to the northeast along the Delaware. It has defined this boundary between Bucks and Philadelphia counties since 1682.

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 three-span, 73-foot-long (22 m) twin stone arch bridge carries Frankford Avenue, just north of Solly Avenue, over Pennypack Creek in Pennypack Park.
The West Philadelphia Elevated, also known as the High Line or Philadelphia High Line, is a railroad viaduct in the western part of Philadelphia, Pennsylvania. Now part of the Harrisburg Subdivision of CSX Transportation, the viaduct was built in 1903 by the Pennsylvania Railroad (PRR) to allow through freight trains to bypass rail yard, industrial sidings, and a passenger station.
The Yardley–Wilburtha Bridge was a bridge spanning the Delaware River. A majority of the bridge was washed away by severe flooding in 1955 and was later demolished in 1961 after the completion of the nearby Scudder Falls Bridge.
The Colossus Bridge – also known as Fairmount Bridge, Colossus of Fairmount or Upper Ferry Bridge – was a record-setting timber bridge across the Schuylkill River near Philadelphia. It was built in 1812 by Louis Wernwag, and was considered his finest bridge design. It had a clear span of 340 feet (103.6 m) and the longest single-span wooden truss to be erected in the United States as well as the first long span bridge to use iron rods.
Wilson Brothers & Company was a prominent Victorian-era architecture and engineering firm established in Philadelphia, Pennsylvania. The company was regarded for its structural expertise.
