"The East Cass Street Bridge is a rare example of a stone arch highway bridge, a type seldom used in Michigan because of the availability of cheap timber. The structure is also uncommon because it has three spans. The East Cass Street Bridge is the only bridge to survive the disastrous flood of 1908 which resulted from the destruction of the dams upstream at Homer, Michigan.
"This documentation was undertakend in April, 1993, in accordance with the Memorandum of Agreement by the Michigan Department of Transportation as a mitigative measure prior to the replacement of the bridge"
