The Hayden Arch Bridge is a concrete arch bridge on old US 14/US 16 in Park County, Wyoming, United States, that is listed on the National Register of Historic Places {NRHP).

The bridge is the only example of its kind in Wyoming. Built in 1924–25, the single-span bridge spans 115 feet (35 m) with two smaller approach arches between rock canyon walls. The bridge carries the Cody-Yellowstone Highway across the Shoshone River with a shallow open-spandrel central arch and nominally arched approach spans. The bridge is named after C. E. Hayden, an engineer with the Wyoming State Highway Department, who designed the bridge and supervised its construction. It was built by H. S. Crocker of Denver, Colorado.
