The connection of the Alaska Highway to the North American railway network at Dawson Creek marked a significant advancement in transportation infrastructure during World War II. Spanning approximately 1,390 miles, the Alaska Highway was initially constructed to support military transport and enhance the strategic defense of Alaska against potential threats. As the United States entered the war, the need for a reliable supply route became critical, particularly as Japanese forces had already occupied parts of the Aleutian Islands. The completion of this vital stretch of railway significantly improved the movement of troops and resources to the region. The project was completed through the dedicated efforts of thousands of workers, many of whom were American soldiers and civilians from various backgrounds, tasked to build roadways and maintain supplies in extreme weather conditions. By connecting to the existing railway network, approximately 2,200 miles of track facilitated the transportation of goods from the continental United States into Alaska, thus aiding in fortifying American defenses.
