New River, AZ
New River is a census-designated place (CDP) in Maricopa County, Arizona, United States. The population was 14,952 at the 2010 census.
New River is named after the seasonal wash of the same name, part of the Agua Fria River system which drains into the Salt River. It was founded by Lord Darrell Duppa in 1868 as a stagecoach stop. For many years it was the terminus of the old Black Canyon Highway (now Interstate 17). The pavement ended in New River and continued as a dirt road to the city of Prescott.
New River has largely retained its rural character; however, its future as a rural community is uncertain as the city of Phoenix expands into the region.
