Summary

Significance: In 1856, the city of Zumbrota was founded by immigrants from Massachusetts, along the Zumbro River on the Dubuque to St. Paul stagecoach trail. The Zumbrota Bridge was first constructed by Evander L. Kingsburg in 1869, using a modified lattice truss designed by A. J. Thatcher. The truss design is unusual in that there are two different angles of lattice members used, with transitional angles used at the center and ends. The varying angled lattice members are connected by bolts to a series of vertical posts, creating a symmetrical pattern. No other lattice trusses are known to have used this unique pattern. Originally built uncovered, the bridge was enclosed in 1871 with board and batten siding and a gabled roof with cedar shingles. The Zumbrota Bridge is Minnesota's last remaining historic covered bridge.
