AMERICAN EXPERIENCE presents Building the Alaska Highway, the story of nearly 11,000 Army engineers who battled freezing temperatures, ice and snow, mountains, mud, muskeg, and mosquitoes to blaze a 1,500-mile road through one of the harshest landscapes in North America, and take a huge step forward in defending the nation from threats in the Pacific. The program interweaves interviews with historians and engineers who built the highway, and presents archival footage and beautiful cinematography of the sub-Arctic route the road took. The film also features never-before-seen home movies of the Alaska Highway.
