The Mule Pass Tunnel is more than just a passage; it's a portal to Bisbee's rich history and stunning landscapes. Before its construction, the only way to reach Bisbee was via the Old Divide Road, a winding and dangerous route over Mule Pass.

Crews worked tirelessly, drilling and blasting through 1,400 feet of granite, using 1,100 tons of steel and 15,000 cubic yards of concrete to reinforce the structure. The tunnel's opening in December 1958 was a major event, celebrated by governors, dignitaries, and the local community.Today, the Mule Pass Tunnel remains Arizona's longest highway tunnel.
