Mule Pass Tunnel Travel Guide

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. The tunnel, commissioned in the late 1950s, was a necessity, eliminating the perilous switchbacks that had plagued travelers for decades.The construction of the tunnel was a significant undertaking, costing $2 million (equivalent to approximately $17.2 million today) and taking 23 months to complete. 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. As you drive or walk through it, take a moment to appreciate the engineering feat and the historical significance of this landmark. Emerging from the tunnel, many feel as if they've stepped back in time, entering an earlier era of Bisbee. The surrounding area offers scenic viewpoints and hiking trails, perfect for exploring the natural beauty of the Mule Mountains. Be sure to look for the erroneous Continental Divide marker near the tunnel, adding a touch of mystery to the site.
