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.

Its Massachusetts segment was known as the Hampshire and Hampden Canal. With the advent of railroads, it was quickly converted to a railroad in the mid-19th century and in recent years has been converted to a multi-use trail after being abandoned for years.

It carries a connecting roadway which joins the Northside Road to New Hampshire Route 110. The bridge was built in either 1857 or 1862, replacing a floating bridge that had been located a short way upstream. It is a two-span Paddleford truss bridge, which is a regional variant of the Long truss. It is 151 feet (46 m) long with a span of 138 feet (42 m), and is 29 feet (8.8 m) wide, carrying an 18-foot (5.5 m) wide roadway and two 6.5-foot (2.0 m) sidewalks. The shore ends of the bridge rest on abutments of granite stone, while the center of the bridge is supported by a reinforced concrete pier, which is flared on the upstream side to deflect debris. The bridge is reinforced with steel beams, giving it a carrying capacity of 15 tons. It is decorated with pendant acorn finials and painted bright white.

The Sulphite Railroad Bridge, also known locally as the Upside-Down Covered Bridge is a historic railroad bridge in Franklin, New Hampshire. The bridge was built circa 1896-7 to carry the tracks of the Boston and Maine Railroad across the Winnipesaukee River between Franklin and Tilton. The bridge is believed to be the only surviving "upside down" covered railroad bridge in the United States, in which the rail bed is laid on top of the bridge roof, whose purpose is to shelter the trusses below. The bridge was listed on the National Register of Historic Places in 1975. The bridge, unused since 1973, is not in good condition, having been subjected to graffiti, vandalism, and arson, as well as the elements.
The Gilsum Stone Arch Bridge carries Surry Road over the Ashuelot River in Gilsum, New Hampshire. Built in 1862–63, it is one of the highest stone arch bridges in the state. It has a span of 47 feet 8 inches (14.53 m), and an average height over the river of 36 feet 6 inches (11.13 m). The roadway is 43 feet 6 inches (13.26 m) above the riverbed. It stands on the site of four previous bridges, where the river passes through a deep gorge. The previous bridge was also a stone arch bridge, which was built in 1860 and collapsed a few months later. It was designed by William Leonard Kingsbury, a local official; its builders are not known because the town's records were destroyed in a fire. The present bridge's vault is carefully constructed from dry-laid granite voussoirs that were shaped for a very precise fit, with larger stones at the lower ends of the arch, and a smaller ones at the crown. Some of the stones were left with rough surfaces, while others were hammered smooth.
The Samuel Morey Memorial Bridge is a historic bridge carrying New Hampshire Route 25A across the Connecticut River between Orford, New Hampshire and Fairlee, Vermont. The steel through-arch bridge was built in 1937–38 to replace an older wooden bridge which had been damaged by flooding in 1936. It spans 432 feet (132 m), stands about 35 feet (11 m) above the river, and its arches rise 85 feet (26 m) above the roadway. It rests on poured concrete abutments that have a light Art Deco or Moderne styling. Wing walls recede from the abutments into the banks in three stepped sections. Below the bridge in the river is visible some riprap, stone remnants of the old bridge's abutments and central pier. The bridge is of a "tied arch" design, in which the two arches are joined together by ties to distribute the active load. This is in contrast to the Justice Harlan Fiske Stone Bridge joining Brattleboro, Vermont and Chesterfield, New Hampshire, which was built about the same time, and distributes the active load to its abutments. The bridge components were manufactured by the American Bridge Company; construction was by Hagen-Thibodeau Construction Company at a contracted cost of just over $209,000.
The Stone Arch Underpass is a historic stone arch bridge spanning Glen Road in Lebanon, New Hampshire. Built about 1848, it carried the Boston and Maine Railroad's former Northern Line.

The bridge was listed on the National Register of Historic Places in 1985. The railroad right-of-way has been functionally abandoned, and the bridge may become part of a continuation of the Northern Rail Trail.
