VITAL ARTERY FOR FLOW OF MILITARY SUPPLIES TO ALASKA.
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Alaska Highway (French: Route de l'Alaska; also known as the Alaskan Highway, Alaska-Canadian Highway, or ALCAN Highway) was constructed during World War II to connect the contiguous United States to Alaska across Canada. It begins at the junction with several Canadian highways in Dawson Creek, British Columbia, and runs to Delta Junction, Alaska, via Whitehorse, Yukon. When it was completed in 1942 it was about 2,700 kilometres (1,700 mi); but in 2012 it was only 2,232 km (1,387 mi). This is due to the continuing reconstruction of the highway, which has rerouted and straightened many sections. The highway opened to the public in 1948. Once legendary for being a rough, challenging drive, the highway is now paved over its entire length. Its component highways are British Columbia Highway 97, Yukon Highway 1 and Alaska Route 2.
An informal system of historic mileposts developed over the years to denote major stopping points. Delta Junction, at the end of the highway, makes reference to its location at "Historic Milepost 1422". It is at this point that the Alaska Highway meets the Richardson Highway, which continues 155 km (96 mi) to the city of Fairbanks. This is often regarded, though unofficially, as the northwestern portion of the Alaska Highway, with Fairbanks at Historic Milepost 1520. Mileposts on this stretch of highway are measured from the port of Valdez on Prince William Sound, rather than the Alaska Highway. The Alaska Highway is popularly (but unofficially) considered part of the Pan-American Highway, which extends south (despite its discontinuity in Panama) to Argentina...
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...
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, 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 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"...
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...
