Susquehanna Depot, often referred to simply as Susquehanna, is a borough in Susquehanna County, Pennsylvania, United States, located on the Susquehanna River 23 miles (37 km) southeast of Binghamton, New York. In the past, railroad locomotives and railroad cars were made here. It is also known for its Pennsylvania Bluestone quarries.
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania, United States; 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 Erie Railroad was a railroad that operated in the northeastern United States, originally connecting New York City — more specifically Jersey City, New Jersey, where Erie's Pavonia Terminal, long demolished, used to stand — with Lake Erie, at Dunkirk, New York. It expanded west to Chicago with its 1865 merger with the former Atlantic and Great Western Railroad, also known as the New York, Pennsylvania and Ohio Railroad. Its mainline route proved influential in the development and economic growth of the Southern Tier of New York State, including cities such as Binghamton, Elmira, and Hornell. The Erie Railroad repair shops were located in Hornell and was Hornell's largest employer. Hornell was also where Erie's mainline split into two routes, one northwest to Buffalo and the other west to Chicago.
The Rockville Bridge is the longest stone masonry arch railroad viaduct ever built, with forty-eight 70-foot spans and a total length of 3,820 feet (1,160 m). The bridge crosses the Susquehanna River about 5 miles (8 km) north of Harrisburg, Pennsylvania. The eastern end is in Rockville and the western end is just south of Marysville.

The Delaware and Hudson Canal was the first venture of the Delaware and Hudson Canal Company, which would later build the Delaware and Hudson Railway. Between 1828 and 1899, the canal's barges carried anthracite coal from the mines of Northeastern Pennsylvania to the Hudson River and thence to market in New York City.
The Columbia–Wrightsville Bridge, officially the Veterans Memorial Bridge, spans the Susquehanna River between Columbia and Wrightsville, Pennsylvania, and carries Pennsylvania Route 462 and BicyclePA Route S. Built originally as the Lancaster-York Intercounty Bridge, construction began in 1929, and the bridge opened September 30, 1930. On November 11, 1980, it was officially dedicated as Veterans Memorial Bridge, though it is still referenced locally as the Columbia–Wrightsville Bridge.
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 Carrollton Viaduct, located over the Gwynns Falls stream near Carroll Park in southwest Baltimore, Maryland, is the first stone masonry bridge for railroad use in the United States, built for the Baltimore and Ohio Railroad, founded 1827, and one of the world's oldest railroad bridges still in use for rail traffic. Construction began in 1828 and was completed in 1829. The bridge is named in honor of Charles Carroll of Carrollton (1737–1832), of Maryland, known for being the last surviving signer of the Declaration of Independence, the only Roman Catholic in the Second Continental Congress (1775–1781), and wealthiest man in the Thirteen Colonies of the time of the American Revolutionary War (1775–1783).
The Thomas Viaduct spans the Patapsco River and Patapsco Valley between Relay, Maryland and Elkridge, Maryland, USA. It was commissioned by the Baltimore and Ohio Railroad (B&O); built between July 4, 1833, and July 4, 1835; and named for Philip E. Thomas, the company's first president. It remains the world's oldest multiple arched stone railroad bridge.
James Pugh Kirkwood was a 19th-century American civil engineer, and general superintendent of the Erie Railroad in the year 1849–1850. He left the Erie to go to the southwest to construct railroads, and he made the first survey for the Pacific Railroad west from the Mississippi to the Rocky Mountains. Late 1860s he served as President of the American Society of Civil Engineers.
Canton Viaduct is a blind arcade cavity wall railroad viaduct in Canton, Massachusetts, built in 1834–35 for the Boston and Providence Railroad (B&P).
Tunkhannock Creek Viaduct is a concrete deck arch bridge on the Nicholson Cutoff rail segment of the Norfolk Southern Railway Sunbury Line that spans Tunkhannock Creek in Nicholson, Pennsylvania. Measuring 2,375 feet (724 m) long and towering 240 feet (73.15 m) when measured from the creek bed, it was the largest concrete structure in the world when completed in 1915 and still merited "the title of largest concrete bridge in America, if not the world" 50 years later.
Bergen Hill refers to the lower Hudson Palisades in New Jersey, where they emerge on Bergen Neck, which in turn is the peninsula between the Hackensack and Hudson Rivers, and their bays. In Hudson County, it reaches a height of 260 feet.
The Stone Bridge spans the Conemaugh River in Johnstown, Pennsylvania. The bridge is a seven-arch stone railroad bridge located on the Norfolk Southern Railway mainline, built by the Pennsylvania Railroad in 1887-88. Its upstream face was reinforced with concrete in 1929.
The Kinzua Bridge or the Kinzua Viaduct was a railroad trestle that spanned Kinzua Creek in McKean County in the U.S. state of Pennsylvania. The bridge was 301 feet (92 m) tall and 2,052 feet (625 m) long. Most of its structure collapsed during a tornado in July 2003.
The Middlefield–Becket Stone Arch Railroad Bridge District is a historic district extending through parts of the towns of Chester, Middlefield, and Becket, Massachusetts. The district encompasses a 3.7-mile (6.0 km) stretch of railroad right of way in which there are ten bridge crossings, including nine over the west branch of the Westfield River. The bridges were built in four time periods: 1840, 1866, 1912, and 1928. Nine of the ten bridges are stone or concrete masonry work, and one is a truss girder bridge. All are, with only minor exceptions, in excellent and original condition. The bridges were built to carry the Western Railroad through on its run from the Connecticut River to the Hudson River. This section of railroad was the most expensive the company had to build, costing over $1 million in 1840.
Pennsylvania Railroad, Connecting Railway Bridge is a stone arch bridge in Philadelphia, Pennsylvania, that carries Amtrak Northeast Corridor rail lines and SEPTA and NJT commuter rail lines over the Schuylkill River. It is located in Fairmount Park, just upstream from the Girard Avenue Bridge.
Julius Walker Adams was an American civil engineer and railroad engineer, who designed the Starrucca Viaduct. He co-founded the American Society of Civil Engineers in 1852 and served as its president from 1874 to 1875.
The Western Railroad Stone Arch Bridges and Chester Factory Village Depot is a National Historic Landmark District extending through parts of the towns of Chester, Middlefield, and Becket, Massachusetts. It encompasses a section of the historic Western Railroad railbed, two stone bridges constructed in the 1840s under the direction of George Washington Whistler, and the c. 1862 railroad depot in the village of Chester Factory, which served the railroad as an important logistics point for the difficult crossing of The Berkshires to the west. The section of railroad was the most expensive the company had to build, costing over $1 million in 1840. A hiking trail providing viewing points to the lower seven bridges was opened in 2004. All of the bridges are viewable via whitewater-appropriate watercraft from the river.
