The Sixth Street Bridge is a four-span, wrought iron bridge that crosses the Grand River in Grand Rapids, Michigan. It is a Michigan State Historic Site and is listed on the National Register of Historic Places. Built in 1886, it is the longest and oldest metal truss bridge in Michigan.HistoryThe Sixth Street Bridge was designed and built in 1886 by the Ohio-based Massillon Bridge Company for $31,000. The westernmost truss was shortened in 1921 when a canal along the river bank was filled in.The bridge faced demolition in 1975, but was saved through the efforts of concerned citizens. The bridge was designated a Michigan State Historic Site (MSHS) on June 18, 1976. On August 13, 1976, it was listed on the National Register of Historic Places. An MSHS informational marker was erected on April 6, 1981. The bridge is also listed on MDOT's Historic Bridge Inventory.In May 2009, the bridge was briefly closed to film scenes of Caught in the Crossfire.The bridge underwent significant renovation in 2012, funded with a $1.8 million federal grant and $472,000 from the Downtown Development Authority. Prior to renovation, the bridge was known for its "creaky" and "bumpy" ride. Painting and sidewalk work took place in April 2012, leaving the bridge accessible for pedestrians. The bridge briefly reopened on May 12 for the Fifth Third River Bank Run. On May 14, the bridge was closed entirely to replace the existing wood decking and asphalt with steel decking and concrete. The project's expected completion date was in August 2012.
