The Upper Twin Falls Bridge is a bridge that spans the Menominee River linking Breitung Township, Michigan, to Florence County, Wisconsin. Completed in 1910, construction was prompted by the erection of a dam downstream. The bridge was closed to automobile traffic in 1971. It was listed on the National Register of Historic Places in December 2012. Read more on Wikipedia
