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 Columbia Bridge is a covered bridge, carrying Columbia Bridge Road over the Connecticut River between Columbia, New Hampshire and Lemington, Vermont. Built in 1911–12, it is one of only two New Hampshire bridges built with Howe trusses, and is one of the last covered bridges built in the historic era of covered bridge construction in both states. It was listed on the National Register of Historic Places in 1976.
The Mount Orne Bridge is a covered bridge over the Connecticut River between Lancaster, New Hampshire, and Lunenburg, Vermont. It joins Elm Street in South Lancaster with River Road in Lunenburg.

The Chicago, Milwaukee, St. Paul and Pacific Railroad Company Historic District consists of the historic right-of-way of the Chicago, Milwaukee, St. Paul and Pacific Railroad in the Bitterroot Mountains from East Portal, Montana, to the mouth of Loop Creek, Idaho, a distance of 14.5 miles (23.3 km). The district was once part of the railroad's mainline from Chicago, Illinois to Tacoma, Washington.
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 Old Stone Arch Bridge is a bridge located in Bound Brook, New Jersey, United States. It is the second-oldest extant bridge in the US, after the Frankford Avenue Bridge over Pennypack Creek in North Philadelphia, Pennsylvania. Built in 1731, it is the oldest bridge in New Jersey. It spans the Green Brook and connects Bound Brook with Middlesex Borough in northern central New Jersey.
The Contoocook Railroad Depot is located in Hopkinton, New Hampshire, United States, in the village of Contoocook. The depot was completed in 1849 as one of the first substantial railroad passenger stations west of Concord on the Concord and Claremont Railroad. The building is one of the best preserved of a small number of gable-roofed railroad stations surviving from the first decade of rail development in New Hampshire. The station exemplifies the pioneering period of rail development in the state.
The Stone Arch Bridge is a stone arch railroad bridge in Keene, New Hampshire, United States. Built in 1847 to carry the Cheshire Railroad, it is one of the best-preserved pre-1850 stone arch bridges in the nation.

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 Arch Bridge is a historic stone arch bridge, carrying Benner Road over the Pemaquid River near the village of Bristol Mills in Bristol, Maine.

The Ottauquechee River Bridge is a steel girder bridge carrying United States Route 5 across the Ottauquechee River in Hartland, Vermont.

The Hawkeye Street Underpass is a historic structure located south of Nora Springs, Iowa, United States. It spans South Hawkeye Street for 28 feet (8.5 m). The Illinois Central Railroad arrived in Nora Springs in 1868, and the Burlington, Cedar Rapids & Northern Railway (BCR&N) arrived three years later. The later was acquired by the Chicago, Rock Island & Pacific Railroad in the early 1880s. This stone masonry arch underpass was constructed by the Rock Island Line in 1889 as part of an upgrade of the tracks. It was designed by F.A. McDonald who had worked for the BCR&N. It is the only known stone arch bridge in Floyd County. The bridge was listed on the National Register of Historic Places in 1998.
The IANR Railroad Underpass is a historic structure located in Cedar Rapids, Iowa, United States. It carried railroad tracks for 24 feet (7.3 m) over Ely Road. The railroad probably built this stone arch bridge, which was completed in 1887. This kind of structure became more popular in the late 19th century as a railroad bridge because it was more durable than metal truss bridges, and they "projected a refined and sophisticated image." It features a semi-circular arch, a beltcourse, coursed-ashlar masonry, stepped wing walls that are flared, a parapet with projecting coping, and an elongated keystone with the date "1887" carved on it. The bridge was listed on the National Register of Historic Places in 1998. It now carries the Cedar River Recreation Trail over the street.
