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. Some claim it to be the world's oldest multiple arched stone railroad bridge. However, the Sankey Viaduct on the Liverpool and Manchester Railway was opened in 1830 and finally completed in 1833.
The Patterson Viaduct was built by the Baltimore and Ohio Railroad (B&O) as part of its Old Main Line during May to December 1829. The viaduct spanned the Patapsco River at Ilchester, Maryland. It was heavily damaged by a flood in 1868 and subsequently replaced with other structures. In 2006, it was restored to limited service when a footbridge was built atop the surviving arch and abutments.
Tunkhannock Creek Viaduct is a concrete deck arch bridge on the Nicholson Cutoff rail line 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.
The Wilmington Rail Viaduct is a series of fills and bridges, about 4 miles (6.4 km) long, that carries the Northeast Corridor through the city of Wilmington, Delaware, above street level. Constructed between 1902 and 1908, the structure consists principally of fills supported by heavy stone retaining walls, punctuated with plate girder bridges over streets, and augmented by a few sections of brick arch viaduct. Its construction is typical of the Pennsylvania Railroad's architectural practices at the time, and the viaduct has been documented by the Historic American Engineering Record and listed on the National Register of Historic Places. Built by the Pennsylvania Railroad (PRR) as part of a series of grade crossing eliminations along the Northeast Corridor, the elevation of the rail line necessitated several other changes to rail infrastructure in Wilmington, including the construction of the Wilmington Shops at the east end of the viaduct, and the construction of the Wilmington Station and adjacent Pennsylvania Railroad Office Building along the elevated right-of-way.

The Chicago, Rock Island and Pacific Railroad Stone Arch Viaduct, also known as the Old Stone Arch, is located northeast of Shelby, Iowa, United States. The span carried the Chicago, Rock Island and Pacific Railroad tracks over Little Silver Creek. It measures 35 feet (11 m) from the water level to the deck, 20 feet (6.1 m) in width, and 30 feet (9.1 m) in length. The bridge has flanking wingwalls that measure 40 feet (12 m) in length. Limestone for the bridge was quarried near Earlham, Iowa and transported by train to the site. It is one of two such bridges known to exist in Shelby County. The Rock Island was the first railroad to enter the county, and continued to operate here into the 1950s. At that time they abandoned the line when the Atlantic cutoff was built providing a more direct route between Atlantic, Iowa and Council Bluffs. While the tracks were removed, the stone arch, the railroad grade, and the right-of-way were left intact. They are now part of the Rock Island Old Stone Arch Nature Trail. The bridge was listed on the National Register of Historic Places in 1998.
