This massive concrete arch bridge crosses Funk Road (now Kilbourne Road) and the Oconomowoc River near North Lake, Wisconsin.
The bridge features three massive concrete arches, each that are 30 feet long. The endwalls of this structure are massively abutted concrete structures.
The bridge has been rebuilt twice since its original construction. In 1928, pipe railings were added to the bridge. In 1945, an extensive overhaul of the bridge obliterated the build date; and strengthened the bridge.
These type of triple concrete arches were built in a number of places by the Milwaukee, Sparta & North Western. These include two crossings of the Menominee River near Milwaukee, and at Beaver Dam.
The 1945 rebuild added some concrete shoring to the bridge. In addition, the bridge was originally double track. The second track was removed in 1959.
Because of the massive size of the bridge; the author has ranked it moderately significant, despite the common design.
