The Gillespie Dam Bridge, sometimes referred to as the Gillespie Dam Highway Bridge, is a through truss bridge spanning the Gila River in Maricopa County, Arizona. It was constructed to bypass a concrete apron through the river in front of the Gillespie Dam, which was often closed by flooding; construction began in 1925 and was completed in 1927. From its opening until 1956 the bridge carried U.S. Route 80, a transcontinental highway between San Diego, California and Tybee Island, Georgia. Maricopa County restored it in 2012 for the Arizona Centennial, adding an educational interpretive centre for visitors, and in 2018 it became part of Historic US 80.
