        The Alaska Highway: How to Build A Road

        The Alaska Highway is a stretch of road that runs 1,520 miles from Dawson Creek, British Columbia to Fairbanks, Alaska. Its construction began in 1942 in the discontinuous permafrost zone, where the soil is frozen solid in some places and boggy in others. Learn about the unexpected geology and weather-related challenges faced by Army road crews as they built over frozen earth and swampland in the midst of changing temperatures, in this interactive activity from American Experience.
