January 23, 2020: Anita Larkin-Ford has made us aware of this event.
The Delaware County Historical Society presented "The Sherman's: Delaware County's Bridge-Building Family". David Simmons, president of the Ohio Bridge Association, explored the prolific bridge building Sherman family.
There were over 60 bridges at one time in Dalware County. Today only the Chambers Road Covered Bridge (WGN #35-21-04) remains.
