which places do u.s. route 80 in arizona connect? From the California border in Yuma to the New Mexico state line near Lordsburg. when was it started? November 11, 1926 was any tunnel constructed here? Yes, the construction of the Mule Pass Tunnel can you give a very brief description of this route? Within the state of Arizona, US 80 made two indirect loops to both Phoenix and Douglas, and the odd shape created by the two "loops" gave US 80 a long length through the state of Arizona. why was the tunnel constructed, any idea? The older route of US 80 over Mule Pass provided a dangerous obstacle for vehicles heading into Bisbee.

U.S. Route 80 in Arizona [SEP] Construction of the Mule Pass Tunnel
By far the largest combined roadway improvement project on US 80 in the 1950s was the construction of the Mule Pass Tunnel and adjoining bypass of downtown Bisbee. Originally constructed as a wagon road in December 1881 and becoming a paved auto highway by the 1920s, the older route of US 80 over Mule Pass (also known as the Old Divide) provided a dangerous obstacle for vehicles heading into Bisbee. It was a common occurrence for large trucks to lose their brakes on the steep grades, resulting injury and in worst cases, death. Furthermore, winter snowfall and ice made crossing the Old Divide sometimes impossible.
