The Significance of the Dunnville Bridge 

Written by C.J. Perkins and C.K. Roise, Hess, Roise and Co. April 1996

The Dunnville Bridge is an excellent example of a steel, Warren overhead truss with verticals. It is among the earliest examples of the Wisconsin Highway Department's use of this design; previously, the agency had employed Pratt and Parker trusses for overhead spans. While a number of Warren truss bridges were subsequently built, less than three dozen examples of this type now survive in the state. The Dunnville Bridge was built by the Worden-Allen Company of Milwaukee, one of the most prolific Wisconsin bridge builders in the early decades of the twentieth century.
