The Wagon Wheel Bridge stretched over 700 feet across the Des Moines River west of the city of Boone.

Its construction and design were unique when it was erected in 1909.  Four spans representing two distinctive truss styles imbued the bridge with a distinctive style and unique quality unmatched by other Des Moines River crossings. The Wagon Wheel Bridge was added to the National Register of Historic Places in 1998. Its four spans remained open to traffic until its closure due to damage from the devastating 2008 floods.

 Sadly, the Wagon Wheel Bridge met its demise in Winter of 2016. An ice jam in February caused significant damage to a vital support pillar causing a center span to twist, contort, and collapse downstream later that March. 

The collapse inflicted significant damage to the connecting spans. Renovation became impossible.

The Wagon Wheel Bridge was demolished following a century of service to the surrounding communities. The remaining spans were removed in their entirety that following June.

[There are several comments noting that the wood planks made a lot of noise when a car crossed the bridge.]

"Significance: This bridge is one of the few remaining large-scale wagon trusses in Iowa. A locally important crossing of a major river, it is one of the few multiple span pin-connected Pratt trusses remaining in the state. One of its four spans is a long-span Pennsylvania through truss, an important sub-type of the Pratt truss." [HAER_data]

The middle diagonal members in the middle panel are smaller because they carry a lighter load. And this photo easily confirms that the truss is pin connected.

This view shows how the middle pier got shoved by an ice flow in Feb 2016 and caused a span to fall into the river on Mar 10, 2016.
