State Route 85, or SR 85, is a state highway in the U.S. state of Arizona. The highway runs from the United States-Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as Southern California.SR 85 was established in 1936 as a route between Gila Bend and Ajo. It was extended southward to the US-Mexico border in 1955, and extended northward to Phoenix when it replaced U.S. Route 80 in 1977. The northern end of the highway was realigned in 1994 onto the connecting highway between I-10 and Buckeye. The remaining portion of the highway between Buckeye and Phoenix was gradually turned over to the cities and county along the route during the 1990s with the final portion turned over in 2001.The southern terminus of SR 85 is located at the United States-Mexico border near Lukeville in Pima County. The road continues across the border into Mexico to the town of Sonoita.
