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 Bollman Truss Railroad Bridge across the Little Patuxent River at Savage, Maryland, is one of the oldest standing iron railroad bridges in the United States and the sole surviving example of a revolutionary design in the history of American bridge engineering. The 160-foot (48.8 m) double-span was built in 1852 at an unknown location on the main line of the Baltimore and Ohio Railroad. It was moved 35 years later to its present location, where it replaced the very first Bollman bridge. Today, it carries the Savage Mill Trail.

Windsor Mills Bridge, also known as Wiswell Road Bridge or Warner Hollow Road Bridge, is a covered bridge that carries Covered Bridge Lane, formerly Wiswell Road, across Phelps Creek in Windsor Township, Ashtabula County, Ohio, United States.

It underwent extensive renovation from 2002 to 2004, and was then reopened to all traffic, except for trucks and buses. The bridge is listed in the National Register of Historic Places.
