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.
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. The bridge, one of currently 17 drivable bridges in the county, is a single-span Town truss design. The bridge was built in 1867 using white pine. It sits atop cut stone abutments, one made of sandstone quarried nearby, and the other made of creek stone. The bridge was bypassed in the 1960s and closed to traffic, and Wiswell Road was rerouted west of the creek. In the 1980s, the bridge was completely closed due to safety reasons. 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. The bridge's WGCB number is 35-04-25, and it is located approximately 5.0 mi (8.0 km) west of Orwell.

The Shinn Covered Bridge is a historic wooden covered bridge in the southeastern part of the U.S. state of Ohio.
