Zehnder's Holzbrücke (German for ''wooden bridge'') is a wooden covered bridge, built in a style similar to those of the [[Black Forest]] or a [[Kapellbrücke|river in Switzerland]], over the Cass River in the middle of town. Though completed in 1979, the two-lane structure was constructed using traditional covered-bridge timber framing techniques. The floor joists and three-span Town [[Lattice truss bridge|lattice truss system]] of the {{convert|239|ft|abbr=on}} bridge are made of {{convert|100000|board feet}} of [[Douglas Fir]], and the decking of {{convert|15960|board feet}} of {{convert|4|in|adj=on}} planks. The area receiving the greatest wear is of oak, while the remainder is spruce. Approximately {{convert|20000|board feet}} of Douglas Fir make up the rafters, and the roof is shingled with cedar. An additional {{convert|4340|board feet}} of pine was required for the bridge side boards. The 230-ton structure was built in place on the east bank of the river, then pulled into position over the river with a capstan and pulleys.  It is wide enough to accommodate two pedestrian walkways in addition to auto traffic.<ref>{{cite web |url=http://my.net-link.net/~michaelf/zehnders.htm |title=Zehnder's Covered Bridge |website=The Covered Bridges of Michigan|access-date=July 11, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20130111062922/http://my.net-link.net/~michaelf/zehnders.htm |archive-date=January 11, 2013 |df=mdy-all }}</ref>
