Pennsylvania Canal Pennsylvania Canal "(or sometimes Pennsylvania Canal system)" refers generally to a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts. The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items. It should be understood the "first use of any railway" in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed Right of ways mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania. Enacted before Railroads gestated during their infancy, the focus of the act was to create through building a canal system, the capability to ship heavy or bulk goods and connect Philadelphia to Pittsburgh—and "more importantly"—and "beyond" to the "new growth markets" in the developing territories reached by the Ohio River now called the midwest. Later, when updated in 1837 to reflect the experience of twelve years of toddler-railways, the term was also applied to railroads and new canals to be added to the state transportation system. As a crowning achievement, the Main Line of Public Works and the Pennsylvania Canal system topped 2100 ft in elevation by erecting the Allegheny Portage Railroad, which used a system of five inclines and five planes on each side of the Eastern Continental Divide at Cresson Pass in Cambria County to actually haul wheeled flat cars, which had halved canal boats placed on them, up and over the Allegheny Front and connect Pittsburgh to the Susquehanna. When finished in 1834 the trip from Philadelphia to Pittsburgh could be made in 3–5 days, weather conditions depending.

Contra Costa Canal The Contra Costa Canal is a 47 mi aqueduct in the U.S. state of California. Its construction began in 1937, with delayed completion until 1948 due to World War II shortages in labor and materials.

Interstate 80 in Pennsylvania The transcontinental Interstate 80 (I-80) is designated across northern Pennsylvania as the Keystone Shortway, officially the Z.H. Confair Memorial Highway. This route was built mainly along a completely new alignment, not paralleling any earlier U.S. Routes, as a shortcut to the tolled Pennsylvania Turnpike and New York State Thruway. It does not serve any major cities in Pennsylvania, and serves mainly as a cross-state route on the Ohio-New York City corridor. Most of I-80's path across the state goes through hilly and mountainous terrain, with relatively flat areas playing home to the freeway toward the western tier of the state.

Port of Pittsburgh The Port of Pittsburgh is a vast river traffic region in southwestern Pennsylvania. It spans a twelve-county area including Allegheny, Armstrong, Beaver, Blair, Butler, Clarion, Fayette, Greene, Indiana, Lawrence, Washington, and Westmoreland Counties. It encompasses essentially all 200 miles of commercially navigable waterways in southwestern Pennsylvania, including the three major rivers in this region: the Allegheny, the Monongahela, and the Ohio. These waterways are made navigable by a system of seventeen locks and dams. The Port of Pittsburgh supports over 200 river terminals and barge industry service suppliers, including privately owned public river terminals. The port complex is served by the CSX and Norfolk Southern railroads and by four interstate highways. The Port of Pittsburgh Commission acts as a comprehensive service for shippers and industries seeking information on the river system.

Folsom South Canal The Folsom South Canal is an aqueduct in Northern California in the United States. The canal diverts water from the American River at Nimbus Dam in Sacramento County and travels about 26.7 mi in a southerly direction, terminating near Clay, about 10 mi northeast of Lodi. The canal is operated by the U.S. Bureau of Reclamation, as part of the Auburn-Folsom South Unit of the Central Valley Project. It is contracted for irrigation, industrial and municipal water supply; formerly it provided cooling water for the Rancho Seco Nuclear Generating Station.

Nescopeck Mountain Nescopeck Mountain (also known as Nescopec Mountain) is a ridge in Columbia County and Luzerne County, in Pennsylvania, in the United States. Its elevation is 1594 ft above sea level. The ridge is a forested ridge, with at least two types of forest and two systems of vernal pools. It is a very long and unbroken ridge with two water gaps: one carved by Catawissa Creek and one carved by Nescopeck Creek. This later gap was exploited as a transportation corridor with the construction of the Lehigh & Susquehanna Turnpike between the respective frontier communities at Lausanne Landing and Nescopeck (opposite bank from Shickshinny, PA on the Susquehanna River) in 1805 connecting the newly developing Wyoming Valley with Philadelphia and the Delaware River valley; cutting off over 100 miles between Philadelphia and Wilkes-Barre. Today's Route PA 93 derives from this historic pack mule road.

Manayunk, Philadelphia Manayunk ( ) is a neighborhood in the northwestern section of the city of Philadelphia, Pennsylvania in the United States. Located on the banks of the Schuylkill River, it contains the first canal begun in the United States (although not the first completed due to budget problems). The area's name comes from the language of the Lenape Indians (later called the Delaware Indians by Europeans). In 1686-dated papers between William Penn and the Lenape, the Lenape referred to the Schuylkill River as "Manaiung", their word for "river", which literally translates as "place to drink"; the word was later altered and adopted as the town's name.

Enlarged Double Lock No. 23, Old Erie Canal Enlarged Double Lock No. 23, Old Erie Canal is a historic Erie canal lock located at Rotterdam in Schenectady County, New York. It was built in 1841-1842 as part of the First Enlargement. It is built entirely of large cut limestone blocks, laid regular ashlar, and mortared with hydraulic cement. The Northeast lock chamber is 110 ft long and 18 ft wide; the Southwest lock chamber is 220 ft long and 18 to 20 ft wide; and the Center pier is 100 ft long and 26 ft wide. The Southwest lock chamber was expanded in 1889-1890. Lock 23 fell into disuse after the opening of the New York State Barge Canal in 1918. The lock chambers contain no water and the area is open as a local park. The site was reclaimed and stabilized by local volunteers starting in 1999. A replica of a board and batten locktender's hut was constructed between 2000 and 2003 by students from the Union College Department of Civil Engineering.
