Wednesday 28th October 1942

The 1,700 mile long Alaska Highway, constructed during World War II for the purpose of connecting the contiguous United States to Alaska through Canada, was completed.
Proposals for a highway to Alaska originated in the 1920s. Thomas MacDonald, director of the U.S. Bureau of Public Roads, dreamed of an international highway spanning the United States and Canada. In order to promote the highway, Slim Williams originally traveled the proposed route by dogsled. Since much of the route would pass through Canada, support from the Canadian government was crucial. However, the Canadian government perceived no value in putting up the required funds to build the road, since the only part of Canada that would benefit was not more than a few thousand people in Yukon.
However, some route consideration was given. The preferred route would pass through the Rocky Mountain Trench from Prince George, British Columbia to Dawson City before turning west to Fairbanks, Alaska.
In 1929 the British Columbia government proposed a highway to Alaska to encourage economic development and tourism. American President Herbert Hoover appointed a board with American and three Canadian members to evaluate the idea. Its 1931 report supported the idea for economic reasons, but both American and Canadian members recognized that a highway would benefit the American military in Alaska; the Great Depression and the Canadian government’s lack of support caused the project to not proceed. When the United States approached Canada again in February 1936, the Canadian government refused to commit to spending money on a road connecting the United States. The Canadians also worried about the military implications, fearing that in a war between Japan and North America, the United States would use the road to prevent Canadian neutrality. During a June 1936 visit to Canada, President Franklin D. Roosevelt told Prime Minister W. L. M. King that a highway to Alaska through Canada could be important in quickly reinforcing the American territory during a foreign crisis. Roosevelt became the first American to publicly discuss the military benefits of a highway in an August speech in Chautauqua, New York. He again mentioned the idea during King’s visit to Washington in March 1937, suggesting that a $30 million highway would be helpful as part of a larger defense against Japan that included, the Americans hoped, a larger Canadian military presence on the Pacific coast. Roosevelt remained a supporter of the highway, telling Cordell Hull in August 1937 that he wanted a road built as soon as possible.
The attack on Pearl Harbor and beginning of the Pacific Theater in World War II, coupled with Japanese threats to the west coast of North America and the Aleutian Islands, changed the priorities for both nations. On February 6, 1942 the construction of the Alaska Highway was approved by the United States Army and the project received the authorization from the U.S. Congress and Roosevelt to proceed five days later. Canada agreed to allow construction as long as the United States bore the full cost, and that the road and other facilities in Canada be turned over to Canadian authority after the war ended.

The official start of construction took place on March 8, 1942 after hundreds of pieces of construction equipment were moved on priority trains by the Northern Alberta Railways to the northeastern part of British Columbia near Mile 0 at Dawson Creek. Construction accelerated through the spring as the winter weather faded away and crews were able to work from both the northern and southern ends; they were spurred on after reports of the Japanese invasion of Kiska Island and Attu Island in the Aleutians. During construction the road was nicknamed the “oil can highway” by the work crews due to the large number of discarded oil cans and fuel drums that marked the road’s progress. On September 24, 1942 crews from both directions met at Mile 588 at what became named Contact Creek,[6] at the British Columbia-Yukon border at the 60th parallel; the entire route was completed October 28, 1942 with the northern linkup at Mile 1202, Beaver Creek, and the highway was dedicated on November 20, 1942 at Soldier’s Summit.
The needs of war dictated the final route, intended to link the airfields of the Northwest Staging Route that conveyed lend-lease aircraft from the United States to the Soviet Union. Thus the long, impractical route over difficult terrain was chosen.
The road was originally built mostly by the U.S. Army Corps of Engineers as a supply route during World War II. In 1942, the Army Corps of Engineers assigned more than 10,000 men, about a third were black soldiers, members of three newly formed “Negro regiments”.There were four main thrusts in building the route: southeast from Delta Junction, Alaska toward a linkup at Beaver Creek, Yukon; north then west from Dawson Creek (an advance group started from Fort Nelson, British Columbia after traveling on winter roads on frozen marshland from railway stations on the Northern Alberta Railways); both east and west from Whitehorse after being ferried in via the White Pass and Yukon Route railway. The Army commandeered equipment of all kinds, including local riverboats, railway locomotives, and housing originally meant for use in southern California.
Although it was completed on October 28, 1942 and its completion was celebrated at Soldier’s Summit on November 21 (and broadcast by radio, the exact outdoor temperature censored due to wartime concerns), the “highway” was not usable by general vehicles until 1943. Even then there were many steep grades, a poor surface, switchbacks to gain and descend hills, and few guardrails. Bridges, which progressed during 1942 from pontoon bridges to temporary log bridges, were replaced with steel bridges where necessary. A replica log bridge, the Canyon Creek bridge, can be seen at the Aishihik River crossing; the bridge was rebuilt in 1987 and refurbished in 2005 by the Yukon government as it is a popular tourist attraction. The easing of the Japanese invasion threat resulted in no more contracts being given to private contractors for upgrading of specific sections.
Some 100 miles (160 km) of route between Burwash Landing and Koidern, Yukon, became nearly impassable in May and June 1943, as the permafrost thawed, no longer protected by a layer of delicate vegetation. A corduroy road was built to restore the route, and corduroy still underlays old sections of highway in the area. Modern construction methods do not allow the permafrost to thaw, either by building a gravel berm on top or replacing the vegetation and soil immediately with gravel. The Burwash-Koidern section, however, is still a problem as the new highway built there in the late 1990s continues to experience frost heave.
