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.

It later closed down due to the closure of the area's lumbermills, until it was converted into a pedestrian bridge in 2019. It is one of the few remaining wrought-iron, Phoenixville bridges still standing, and the oldest intact bridge in the state of Oregon.
