For nearly 20 years, SWCA assisted Pinal County in Arizona with the Kelvin Bridge Replacement Project. In the late 1990s, the county began seeking funding to replace the historic Kelvin Bridge. Located in a rural Sonoran Desert area between State Route 79 in Florence and State Route 177 in Kearny, the Kelvin Bridge crosses the Gila River, one of Arizona’s few perennial rivers, and provides a convenient route between eastern and western portions of Pinal County along the 32-mile Florence-Kelvin Highway.
