The town of Winkelman, on the border of Pinal and Gila counties, has a distinctive bridge claim to fame.
The Winkelman Bridge began life back in 1915, when the Pinal County Board of Supervisors appropriated $52,000 from a $500,000 bond issue to build it. Because Winkelman is located on the border of Pinal and Gila counties, Gila County agreed to pay half of the construction cost. At the advice of Assistant State Engineer T.M. Nichols, the structure would be built using multiple-span concrete arches.
