The Bollman Truss Railroad Bridge at Savage, Maryland is the sole surviving example of a revolutionary design in the history of American bridge engineering. The 160-foot (48.8 m) double-span truss bridge is one of the oldest standing iron railroad bridges in the United States. Currently, however, it is in use carrying the Savage Mill Trail across the Little Patuxent River. It was the first successful all-metal bridge design to be adopted and consistently used on a railroad. The type was named for its inventor, Wendel Bollman, a self-educated Baltimore civil engineer.

The Meadow Bridge was a historic bridge across the Androscoggin River located on a spur of North Road in Shelburne, New Hampshire. It was a multi-span pin-connected truss bridge that was the first on its site when it was built in 1897 by the Groton Bridge and Manufacturing Co. The bridge consisted of three central through Pratt trusses, one pony Pratt truss, and one steel girder section. The ends of the bridge rested on stone abutments, while the interior spans were supported by circular steel piers filled with concrete and anchored in place by timber piles. The bridge was bypassed in 1984 by a modern bridge. In 2004 it was dismantled and stored on the banks of the river for future rehabilitation.

The ERT Bridge over Black's Fork near Fort Bridger, Wyoming was listed on the National Register of Historic Places in 1985 as part of a thematic study on early 20th century steel truss bridges in Wyoming. The ERT Bridge is a Warren pony truss bridge spanning 80 feet (24 m) with a width of 15.75 feet (4.80 m). Set on concrete abutments, the ERT Bridge was built around 1920 by Uinta County. It is an example of a transitional design from locally-built bridges to standardized State designs
The Braley Covered Bridge, also called the Johnson Covered Bridge and Upper Blaisdell Covered Bridge, is a wooden covered bridge that crosses the Second Branch of the White River in Randolph, Vermont on Braley Covered Bridge Road.

The Depoe Bay Bridge is one of a series of significant bridges along the Oregon Coast Highway. The concrete arch bridge spans the mouth of Depoe Bay at milepost 127.61 with a 150-foot (46 m) main span, and a total length of 312 feet (95 m). The bridge's designer was Conde McCullough who designed all of the 1920s bridges on the highway. The original bridge, completed in 1927, was only 18 feet (5.5 m) wide from curb to curb with no sidewalks, and was widened in 1940 with a similar arched concrete bridge immediately adjacent to the original. The added structure is sympathetic to the original and is included in the National Register of Historic Places listing.
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 Little Buffalo River Bridge is a historic bridge in central Newton County, Arkansas. The bridge carries Arkansas Highway 327 across the Little Buffalo River between Parthenon and Jasper.
