A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently.
The Detroit–Superior Bridge or Detroit–Superior High Level Bridge is a 3,112-foot-long (949 m) through arch bridge over the Cuyahoga River in Cleveland, Ohio. The bridge links Detroit Avenue on Cleveland's west side and Superior Avenue on Cleveland's east side, terminating west of Public Square. Construction by the King Bridge Company began in 1914 and completed in 1918, at a cost of $5.4 million. It was the first fixed high level bridge in Cleveland, and the third high-level bridge above the Cuyahoga. At the time of its completion, the bridge was the largest steel and concrete reinforced bridge in the world.

The Mill Creek Bridge is located north of Cherokee, Iowa, United States. It spans Mill Creek for 207 feet (63 m). On June 24, 1891, a disastrous flood along the Little Sioux River and its tributaries wiped out nearly every bridge in Cherokee County. The following month the county board of supervisors signed a contract with the George E. King Bridge Co. of Des Moines for 17,650 to replace the bridges. This Pratt truss bridge was fabricated by the King Bridge Company of Cleveland, Ohio. It and a similar span over Mill Creek near Larrabee are the only two that remain. This bridge was listed on the National Register of Historic Places in 1998. A modern concrete span, built just upstream in 2006, now carries the road. The old bridge is closed to vehicular traffic.
The Adel Bridge is located on the east edge of Adel, Iowa, United States. The 400-foot (120 m) span carried traffic on River Street over the Raccoon River. The Dallas County Board of Supervisors received a petition to replace a deteriorating bridge at this location. The old bridge had been built where ferry service had been initiated in 1850, three years after the town had been established. They contracted with the King Iron Bridge and Manufacturing of Cleveland to build the two-span Pratt through truss bridge for $12,500. It was a primary river crossing into Adel until 1932 when the U.S. Highway 6 bridge was completed not far to the south. While it remains in place, it was closed to vehicular traffic in 2000. The bridge was listed on the National Register of Historic Places in 2002.

The bridge was listed on the National Register of Historic Places in 1998. The span was moved in 2008.
Lower Road Bridge is a historic structure located northwest of Anamosa, Iowa, United States. It spans Buffalo Creek for 160 feet (49 m).

The bridge's superstructure consists of a large stone masonry pier and abutments. It was listed on the National Register of Historic Places in 1998. The county abandoned the bridge and it is now privately owned.
Corbett's/Eby's Mill Bridge is a historic structure located northeast of Scotch Grove, Iowa, United States. It spans the Maquoketa River for 128 feet (39 m). James S. Applegate established a gristmill near this location in 1858. He was joined by John Corbett, who obtained ownership by 1868 and expanded the operation and added a sawmill. He petitioned the Jones County Board of Supervisors for an iron bridge at this location in 1870. They agreed to pay two-thirds of the construction costs with the final third paid for by local subscriptions. The contract to construct this bridge and a similar span in Monticello was made with Miller, Jamison & Company of Cleveland. Both are single span bowstring truss bridges that were completed in November 1871. This bridge has always been identified with the mill. Samuel Eby acquired it in 1875, and it remained in the family until 1913. The bridge was originally on a loop road that circled behind the mill pond. When County Road X73 was created in 1958 it bypassed the bridge to the south. The bridge has been under private ownership ever since. It was listed on the National Register of Historic Places in 1985.
The Fish Creek Bridge is a historic structure that was originally located east of Salem, Iowa, United States. The span carried Hickory Road over Fish Creek for 50 feet (15 m). It is a small-scale, wrought-iron bridge that the Henry County Board of Supervisors bought from the George E. King Bridge Company of Des Moines in 1893 for $410.80. It was believed to have been fabricated by their parent company, King Iron Bridge Company of Cleveland, and assembled by local laborers. Its historical significance derived from its being an uncommon variant of the Pratt truss. It was listed on the National Register of Historic Places in 1998. Subsequently, the bridge has been replaced at its original location, and the historic structure was moved to Oakland Mills Park.
The Oakland Mills Bridge is a historic structure located in Oakland Mills Park southwest of Mount Pleasant, Iowa, United States. The span carried Hickory Road over the Skunk River for 358 feet (109 m). In July 1876 the Henry County Board of Supervisors decided to locate the bridge over the Skunk River at Oakland Mills.

The long-span combination Pratt truss through and pony truss was completed later the same year. The steel components where manufactured by the Phoenix Iron Company of Pennsylvania. It is one of the oldest Pratt through truss bridges in Iowa. Long closed to vehicular traffic, it was listed on the National Register of Historic Places in 1998.
