"This single span iron bride was included in the National Register of Historic Places on October 12, 1994. Constructed in 1889, the bridge is the only Michigan example and the oldest of the three known surviving examples in the United States of the Thatcher metal through truss bridge.
"The bridge will be replaced with a new wider bridge at the site of the existing structure. The bridge was recorded in 1996 by Joseph G. Periard of the Saginaw Road Commission, 3020 Sheridan Avenue, Saginaw, Michigan 48605. The report draws heavily from the Parshallburg Bridge National Register of Historic Places registration form prepared by Robert O. Christensen, National Registger Coordinator for the Michigan State Historic Preservation Office, Bureau of Michigan History."
