This small concrete and stone arch bridge crosses the Oconomowoc River east of Oconomowoc.
This bridge is an example of an early 1900s arch that was built as a concrete arch, but included a stone and brick lining. This stone lining is included because it makes the arch super strong on the outside, and the interior arch is constructed of brick.
Concrete oftentimes crumbles in the arch lining. Using stone creates a durable lining. In addition, the interior is lined with brick.
This bridge was built in 1902, likely to replace a truss. At this time; the line was double tracked. This bridge sits parallel to WI-16.
The author has ranked this bridge as being locally significant, due to the common nature of this design. However, the arch lining is a unique feature and a very innovative way to build a bridge that lasts.
