Dunn's Bridge

Dunns Bridge is located at 41°13′10″N 86°58′09″W. The bridge is rumored to be built at least partially from materials obtained from the original Ferris wheel at the 1893 World's Columbian Exposition in Chicago. The current maintainers of the bridge, the Porter County Parks Department, state only that it is "built from parts of a building from the 1893 Chicago World's Fair."[3] Upon a cursory look at the lack of parallelness of the tops of the arches (flattening), the Ferris Wheel heritage is impossible. More likely, the arches may have been salvaged from a building at that exposition and the general similarity to a wheel was noted and the misinformation took root as legend.

There are four small sections, two at each end, that appear to be ornamental. These smaller sections have the right radius for a ferris wheel. The radius and arch shape match that of Machinery Hall or Electricity Hall from the Exposition. Machinery Hall burned and the steel was sold as scrap at about the time the bridge was built.

The bridge was renovated in 2003, winning a state award for the engineering work involved.
