Stillwater Lift Bridge

The Stillwater Bridge is a vertical-lift bridge crossing the St. Croix River between Stillwater, Minnesota, and Houlton, Wisconsin. It formerly connected Minnesota State Highway 36 and Wisconsin Highway 64. Around 18,000 vehicles crossed the bridge daily. The new St. Croix Crossing bridge crossing the St. Croix river valley to the south of Stillwater replaced its purpose, having opened to highway traffic on August 2, 2017, leaving the Stillwater Lift Bridge to be preserved and to be converted to bicycle/pedestrian use.

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 nominated for being a rare surviving example of a vertical-lift highway bridge based on the designs pioneered by Waddell & Harrington.
