A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last 100 years.

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. Truss bridges are one of the oldest types of modern bridges. 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 Philadelphia & Reading Railroad Bridge carries Norfolk Southern rail lines across the Susquehanna River between Cumberland County, Pennsylvania and Harrisburg, Pennsylvania. Some of its concrete piers encase stone masonry piers from an earlier truss bridge on this site, completed in 1891 by the Philadelphia, Harrisburg and Pittsburgh Railroad, which was then acquired by the Philadelphia and Reading Railroad to connect its Harrisburg and Lurgan lines. The current structure was constructed from 1920 to 1924 by replacing the trusses with concrete arches one track at a time. The bridge has fifty-one concrete arches, three more than the nearby Rockville Bridge.
