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 Starr Mill Road Bridge is a historic bridge in Middletown, Connecticut. It is a single span Warren through truss bridge, spanning the Coginchaug River near the Starr Mill complex on the west bank of the river.

It was formed to take over the operations of the bankrupt Burlington, Cedar Rapids and Minnesota Railway, which was, in turn, the result of merging several predecessor lines, the construction of which began in 1869. The corporate headquarters were in Cedar Rapids, Iowa, and it had operations in Iowa and in Minnesota. It was succeeded by the Chicago, Rock Island and Pacific Railway.

Nodaway River Bridge is located west of Grant, Iowa, United States. It spans an arm of a small pond in Pilot Grove County Park for 70 feet (21 m). The Montgomery County Board of Supervisors accepted a petition from S. M. Smith to build a bridge over the Nodaway River south of Grant in June 1876, and another bridge over the Nishnabotna River at the same time. The county contracted with the Missouri Valley Bridge & Iron Co. of Leavenworth, Kansas, to design and build the Nodaway River bridge, which was completed later the same year for $1,000. The bridge consists of a single-span Bowstring arch-truss with a wood deck. It remained in use as a road bridge until 1968, when it was moved to the park for use as a pedestrian bridge. Even though it is no longer in its historic location and used for its historic function, the bridge was listed on the National Register of Historic Places in 1998 as an example of early transportation development in Iowa.
The Red Bridge is located just northeast of Monroe, Iowa, United States. The 212-foot (65 m) span carried traffic on County Road S74 over the South Skunk River. This is one of the few Warren truss bridges built in Iowa in the 19th century. Local bridge contractor H.S. Efnor built the main span for $3,515.34 in 1892.

The truss bridge was designed by the Iowa State Highway Commission, and constructed by the Iowa Bridge Company. It was completed in 1920, and was moved to its present location sometime later. Even though it is no longer in its historic location, the bridge was listed on the National Register of Historic Places in 1998 as the longest pinned connected truss bridge in Iowa.

The Green Mill Ford Bridge was a historic structure located northeast of Janesville, Iowa, United States. It spanned the Cedar River for 244 feet (74 m).
