Summary of Historic Significance
The Third Street Bridge is a steel, single-span, riveted Pennsylvania through truss bridge. As a bridge with riveted panel intersections, it could span a greater distance than the simpler pin connections of the Pratt and Warren trusses. The bridge is historically significant as representative of an unusual type of truss span in Minnesota and for its associations with Minneapolis bridge builder, A.Y. Bayne, and the St. Paul engineering firm of Loweth and Wolff. It was constructed in 1909-1910, near the middle of Bayne's career as an independent bridge builder.
