Chester Bridge 

Written by H. John Dobrovolny, Regional Historic Preservation Officer, U.S. Fish & Wildlife Service

Chester Bridge is considered important in Wisconsin history because it is a type of bridge that is rapidly disappearing in the State, it is a link in the development of truss bridge construction, and it is an early example of a bridge built by the Wisconsin Bridge and Iron Company.
