Significance of the Polley Lane Bridge

Written by Robert Newberry, Wisconsin DOT & Amy Ross, Mead and Hunt, Inc., 1986

The Polley Lane Bridge is representative of Pratt overhead trusses built between 1895 and 1910. These bridges are a transitional group, between the wagon bridge of the mid-to-late nineteenth century and the automobile-carrying structure of the twentieth century. Thus, the Polley Lane Bridge has pin connections for the major joints, light and slender members in the truss web, and a wood deck. The structural material was steel, however, and the floor beams were rolled sections. The bridge's 110-foot span is in the average range for similar overhead Pratt trusses in Wisconsin.
