In 1946 the US military turned the rustic route over to the Canadian Army. The section between Destruction Bay and Beaver Creek was impassable for a period due to the permafrost melt & mud.
In 1948 the highway was opened to public travel as part of the Northwest Highway System.
My Dad drove to Yukon from Alberta in 1952. He worked at Snag, one of the air bases on the Northwest Staging Route. Dad met Mom on his numerous trips on the Alaska Hwy into Whitehorse from Snag, when she was working at a lodge at Destruction Bay, Mile 1083.
His baby Suzy was born in 1958 and raised at Mile 1202 and then Mile 1204. Between 1958 and 1963 Dad worked for Canada Customs at Mile 1202 and also DPW (Department of Public Works) where his job was to grade and repair the Alaska Highway so the public could continue to travel along it.
At Mile 1204 Dad worked as a civilian employee for the US Army on the Haines-Fairbanks pipeline. We drove the 285 miles into town (Whitehorse) often. Back then it was an 8 to 10-hour day to make the trip one-way. I remember sections of corduroy road in the Beaver Creek area.
I have Alaska Highway dust in my veins, and my bones continue to be rattled by the route daily.
Here are some images from the mid-1950s:

Wrecks like this were typical on the Alaska Highway and Dad photographed every one he saw
