The National Road was the first major improved highway in the United States built by the federal government. Built between 1811 and 1837, the 620-mile (1,000 km) road connected the Potomac and Ohio Rivers and was a main transport path to the West for thousands of settlers. When improved in the 1830s, it became the second U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam.

Rockwood is a borough in Somerset County, Pennsylvania, United States. The population was 850 at the 2020 census. It is part of the Johnstown, Pennsylvania, Metropolitan Statistical Area, and located due north of Pennsylvania's highest peak, Mount Davis, which significantly constricts land travel routing south of the municipality.
John Augustus Roebling was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark.
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States. It operated as B&O from 1830 until 1987, when it was merged into the Chessie System; its lines are today controlled by CSX Transportation.
South Park is an American animated television series.
A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania. It operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Approximately 36 miles (58 km) long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service.
The Richmond, Fredericksburg, and Potomac Railroad was a railroad connecting Richmond, Virginia, to Washington, D.C. The track is now the RF&P Subdivision of the CSX Transportation system; the original corporation is no longer a railroad company.
The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. designed it and supervised construction of what became the first bridge to span a major river west of the Appalachian mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements applied in later years until it was closed to automobile traffic in September 2019.
The Washington and Old Dominion Railroad was an intrastate short-line railroad located in Northern Virginia, United States. The railroad was a successor to the bankrupt Washington and Old Dominion Railway and to several earlier railroads, the first of which began operating in 1859. The railroad closed in 1968.
The National Register of Historic Places in the United States is a register including buildings, sites, structures, districts, and objects. The Register automatically includes all National Historic Landmarks as well as all historic areas administered by the U.S. National Park Service. Since its introduction in 1966, more than 90,000 separate listings have been added to the register.
The Pittsburgh and West Virginia Railway was a railroad in the Pittsburgh, Pennsylvania, and Wheeling, West Virginia, areas. Originally built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of George J. Gould's Wabash Railroad, the venture entered receivership in 1908 and the line was cut loose. An extension completed in 1931 connected it to the Western Maryland Railway at Connellsville, Pennsylvania, forming part of the Alphabet Route, a coalition of independent lines between the Northeastern United States and the Midwest. It was leased by the Norfolk and Western Railway in 1964 in conjunction with the N&W acquiring several other sections of the former Alphabet Route, but was leased to the new spinoff Wheeling and Lake Erie Railway in 1990, just months before the N&W was merged into the Norfolk Southern Railway.
The Northern Central Railway (NCRY) was a Class I Railroad in the United States connecting Baltimore, Maryland, with Sunbury, Pennsylvania, along the Susquehanna River. Completed in 1858, the line came under the control of the Pennsylvania Railroad (PRR) in 1861, when the PRR acquired a controlling interest in the Northern Central's stock to compete with the rival Baltimore and Ohio Railroad (B&O).
A large metropolitan area that is surrounded by rivers and hills, Pittsburgh has an infrastructure system that has been built out over the years to include roads, tunnels, bridges, railroads, inclines, bike paths, and stairways; however, the hills and rivers still form many barriers to transportation within the city.
The Alexandria Canal was a canal in the United States that connected the city of Alexandria to Georgetown in the District of Columbia.
The Cumberland Valley Railroad was an early railroad in Pennsylvania, United States, originally chartered in 1831 to connect with Pennsylvania's Main Line of Public Works. Freight and passenger service in the Cumberland Valley in south central Pennsylvania from near Harrisburg to Chambersburg began in 1837, with service later extended to Hagerstown, Maryland, and then extending into the Shenandoah Valley to Winchester, Virginia. It employed up to 1,800 workers.
U.S. Route 40 enters Pennsylvania at West Alexander. It closely parallels Interstate 70 (I-70) from West Virginia until it reaches Washington, where it follows Jefferson Avenue and Maiden Street. In Washington, US 40 passes to the south of Washington & Jefferson College. Following Maiden Street out of town, the road turns southeast toward the town of California. A short limited access highway in California and West Brownsville provides an approach to the Lane Bane Bridge across the Monongahela River. From here, the road continues southeast to Uniontown.
