U.S. Route 95 (US 95) is a major U.S. Highway in the American state of Arizona. Starting at the Mexican border in San Luis, US 95 acts as the main highway north through Gadsden, Somerton and Yuma before arriving in Quartzsite. Between Quartzsite and the California border on the Colorado River in Ehrenberg, US 95 runs entirely concurrent with I-10. Part of US 95 between San Luis and Yuma is maintained by local governments instead of the Arizona Department of Transportation, which maintains the remainder of the route.
