"A politically prominent local citizen built the South Main Street Bridge on the basis of moderately early reinforced concrete arch design. The designers decorated the structure in City Beautiful style to complement the municipal improvement efforts of Eaton Rapids. The Michigan State Historic Preservation Office has declared the bridge eligible for listing in the National Register of Historic Places.

"HH Engineering or Grand Rapids, Michigan documented the South Main Street Bridge concomitant with the structure's demolition under a memorandum of agreement with the Michigan Department of Transportation.

"Mr. Alan L. Halbeisen observed and recorded features of the structure during demolition from 30 May to 23 June, 1995. Dr. James L. Cooper prepared the text 29 November, 1995."
