Third Street Bridge (Bridge L5391)
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.
Completed in 2021, the bridge underwent repairs to address the conditions to the bridge's deck, truss structure, bearings, concrete abutments and wingwalls, and railings. Some highlighted repairs included: truss bearings were replaced with new elastomeric bearing pads, deteriorated/missing railing endposts were replaced with cast replicas, timber bridge deck was replaced with a new concrete deck, backwalls of the existing concrete abutments were replaced, bridge was repainted in a historically appropriate neutral gray, and the name and date plaques above each portal were cleaned and preserved.
