To mark the week that Minnesota DOT lowers the Stillwater Lift Bridge for the winter, here’s a five-minute video about the history of the bridge! This iconic vertical-lift bridge has graced the St. Croix River crossing between Stillwater, Minnesota, and Houlton, Wisconsin since 1931. The bridge was listed on the National Register of Historic Places in 1989 for having state-level significance in the theme of engineering. It was also nominated for being a rare surviving example of a vertical-lift highway bridge based on the designs pioneered by Waddell & Harrington!
