MAA Found Math 2012 - Week 44

MAA Found Math: Stephen J. Wilson (Iowa State University) sent us this photo of the High Trestle Bridge across the Des Moines River between Madrid and Woodward, Iowa. A spiral is formed as the 41 square structures rotate along the span of the bridge. We originally featured this bridge on July 11, 2011.
