In 1941, the U.S. Congress appropriated $5 million to construct a 2.5 mile tunnel to penetrate the mountains to connect Whittier to Anchorage. This tunnel would be one of the largest in the world, and two years and two tunnels later, the first train arrived in Whittier on June 1, 1943, forever linking this Alaskan outpost by sea and land.
By the year 2000, the tunnel began to serve both vehicles and the train. Two of the largest buildings in Alaska were also constructed in Whittier during the war, with the unique concept of housing all residents under one roof. To this day, most of the population of 185 lives in one of these tall buildings, and its tiny boat harbor remains the gateway to the pristine wonders of the beautiful Prince William Sound wilderness.
