Drive North America's Longest Tunnel

At 2.7 miles in length, the Anton Anderson Memorial Tunnel is the longest combined vehicle and railroad tunnel in North America. It’s also the only way to get to Whittier by land. The one-lane tunnel operates on a private schedule, alternating between service for private cars and the Alaska Railroad every half-hour. The engineering marvel cuts completely through Maynard Mountain and is designed to withstand temperatures as low as minus 40 degrees Fahrenheit and winds as high as 150 miles per hour. The historic tunnel was constructed by the military during World War II to deliver goods from the port via railroad. A combination of portal and jet turbine ventilation fans air out the tunnel between direction changes. Passengers onboard the Alaska Railroad experience complete darkness for two minutes while the train winds through the inside of the mountain. Well worth the wait, the light at the end of the tunnel offers stunning views of glaciers and the coastal community.
