About this Bridge:
The method used in constructing this bridge was innovative, in that the old bridge being replaced was left standing and used as falsework to support the new structure, before being removed. This is one of only three steel arch bridges in Michigan and is a massive structure, measuring 42 feet wide and 257 feet in length. The Michigan State Highway Department designed the structure and the builders were Fry & Kain, Inc. and Robert Hudson.
