The Tivoli Island Bridge was part of a four span bridge across the Crawfish River in Milford, Wisconsin. When it was replaced, two of the spans came here, one reportedly went to Fort Atkinson and the whereabouts of the fourth span are lost to history.

Overview
Bowstring pony truss bridge over Rock River on Pedestrian Walkway in Watertown
Location
Watertown, Jefferson County, Wisconsin
History
Built 1877 over Crawfish River in Milford; Moved to Watertown 1906
Builder
- King Bridge Co. of Cleveland, Ohio
Design
"In 1866, Zenas King from Ohio received a patent for an innovative tubular iron-arch design. Increasing the sectional area of the top chord toward the ends of the arch, he claimed, strengthened the bridge. Built c. 1877, the Tivoli Island Bridge incorporated this design principle. The King Iron & Bridge Manufacturing Company in Cleveland, Ohio, popularized the tubular iron-arch by numerous examples throughout the United States.

"Apparently, the Tivoli Island Bridge was originally part of a four-span structure over the Crawfish River in the village of Milford. In 1906, two Watertown residents arranged to have the two-span section moved to its present location at Tivoli Island. In Wisconsin, the bridge is one of only seven remaining bowstrings and the last example of a tubular arch design."
--Diane Kromm, Wisconsin Historic Bridge Recording Project, July 1987

Good catch! I was going to document this one, but you beat me to it. Hope to see more from you.

My guess is, and I suspect, the running boards allow the parks people to take maintenance motor vehicles across the bridge to the island.

Why does a bridge that is a pedestrian walkway have running boards?
