The Waterford Bridge, formerly designated Bridge L0327 and now Bridge L3275, is a historic steel truss bridge over the Cannon River in Waterford Township, Minnesota, United States. It was constructed in 1909 and is one of the state's earliest surviving bridges to use rigid rather than pinned connections. Moreover, it is Minnesota's only known road bridge in which some of the rigid connections are fastened with bolts rather than rivets. Read more on Wikipedia
