US 191 begins in Cochise County, Arizona at a signaled intersection with Arizona State Route 80 (SR 80) and Historic U.S. Route 80 (Historic US 80) near Douglas. [1] The highway then proceeds north past Bisbee Douglas International Airport passing through the hamlets of Elfrida and McNeal. Near Sunizona, US 191 intersects with the western terminus of SR 181. US 191 then curves west for 7.5 miles (12.1 km) before turning northwest through Sunsites and Cochise. US 191 intersects Interstate 10 (I-10) near Cochise at a trumpet interchange (I-10 Exit 331). US 191 and I-10 run concurrent for 20.9 miles (33.6 km) around Willcox. In Willcox, I-10/US 191 serves as the northern terminus for SR 186 at Exit 340. The city itself is served by the Willcox I-10 Business Loop, which begins and ends at I-10/US 191 southwest and northeast of the city. In Bowie Junction at Exit 352, US 191 leaves I-10 and heads north, exiting Cochise County and entering Graham County. [2]
