History and significance

The Third Street Bridge is a steel, single-span, riveted Pennsylvania through truss that carries Third Street North over the Cannon River in Cannon Falls, Goodhue County.  The bridge was constructed in 1910 and possesses ornamental features including a decorative railing, endposts, and bridge builder’s plaque.  The Third Street Bridge is significant as a representative example of a Pennsylvania through truss, an unusual type in Minnesota.  It is also historically significant for its associations with Minneapolis bridge builder, A.Y. Bayne, and the Saint Paul engineering firm of Loweth and Wolff, both important in Minnesota.
