In May of 1942, across the rugged sub-Arctic wilderness of Alaska and Canada, thousands of American soldiers began one of the biggest and most difficult construction projects ever undertaken-building the Alaska Highway. This program tells how young soldiers battled mud, muskeg, and mosquitoes; endured ice, snow, and bitter cold; and cut pathways through primeval forests to push a 1,520-mile road across one of the world's harshest landscapes.
