This massive deck truss bridge is an icon in Wisconsin Dells, which has become a major tourist destination over the past decades.
The area used to be known as Kilbourn, and this bridge was identified with that community.

The bridge contains a pair of 6-panel, pin connected Pratt Deck Trusses, which sit on concrete substructures.
These spans are approached by deck girder spans, one of which rests on a stone abutment. The newer span over Broadway was built in 1955 and rests on a concrete abutment.

This bridge was built in 1903 to replace an older Whipple Deck Truss span.

One unique feature of the bridge was the double deck design. The bottom of the truss originally carried a road.
This road was likely discontinued by 1955, when the new Broadway Bridge was built. This new span crosses WI-31, WI-16 and WI-23.

Overall, the bridge is a local landmark. However, this does not mask the structural problems that have begun to form in the deteriorating structure. H-Columns have had to be installed to prevent the upper deck from failing.
In addition, the former westbound track has not been used in some time. This could be because of load ratings.
The bridge is rated as regionally significant, because of the landmark status to the area, as well as the odd combination design. This bridge is also likely a candidate for replacement within the near future, elevating its status even more.

The author hopes that if the will ever came to be, the bottom deck could be reused as a observation and pedestrian deck. The photo above is an overview.
