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 may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
The Colorado River Bridge at Bastrop is a 1,285-foot (392 m)-long bridge with three steel truss spans and concrete piers that crosses the Colorado River as part of Loop 150 through Bastrop, Texas. The three bridge spans over the river consist of identical Parker through trusses, each 192 feet (59 m) in length, supported on concrete piers. The bridge is one of the earliest surviving uses of the Parker truss in Texas.
Chevelon Creek Bridge is a historic road bridge located about 12 miles (19 km) southeast of Winslow, in Navajo County, eastern Arizona, United States.

The Kettle Falls Bridges is the collective name for a pair of steel cantilever bridges carrying State Route 20/U.S. Route 395 and the Kettle Falls International Railway across the Columbia River at Kettle Falls, Washington.

The Yale Bridge or Lewis River Bridge spans the Lewis River near Yale, Washington. It was built in 1932 by Cowlitz and Clark counties. The suspension bridge has a clear span of 300 feet (91 m), with a total length of 532 feet (162 m), replacing a previous steel truss bridge at the site. Construction of the Ariel Dam had created Lake Merwin with a water depth of 90 feet (27 m) at the site, requiring a new bridge that did not need to have support piers in the water. The road deck, stiffened by a steel Warren truss, is 50 feet (15 m) above the high water line of the reservoir.
