Fossil Creek Bridge, Road bridge in Gila County, Arizona, United States

Fossil Creek Bridge is a closed-spandrel deck arch bridge with a 70-foot span and a 14-foot arch rise, carrying Fossil Creek Road across the creek where it forms the border between Yavapai and Gila counties. Its Luten arch-like reinforcing and bulkheads were designed by the Arizona Highway Department in 1924.

The Arizona Highway Department designed the bridge in early 1924 and completed it later that year at a cost of $10,037. It was built on the Cottonwood–Camp Verde–Pine road where Fossil Creek marks the Yavapai–Gila county line. The structure was later listed on the National Register of Historic Places.

The bridge carries Fossil Creek Road at the line between Yavapai and Gila counties and between the Tonto and Prescott National Forests, so a crossing here passes from one county and one forest into the other. The nearest town is Strawberry, in Gila County, with Camp Verde not far off in Yavapai County.

The bridge is accessible via Fossil Creek Road in a rural setting between the two national forests. Visitors should be aware that this is a remote location and plan accordingly for a visit.

The bridge's 70-foot span and 14-foot arch rise were built for $10,037, and its reinforcing follows the Luten arch pattern with bulkheads. The Arizona Highway Department designed it in early 1924 and finished it the same year, where Fossil Creek marks the Yavapai-Gila county line.
