Once a small farming community, Dawson Creek became a regional centre after the western terminus of the Northern Alberta Railways was extended there in 1932. The community grew rapidly in 1942 as the US Army used the rail terminus as a transshipment point during construction of the Alaska Highway. In the 1950s, the city was connected to the interior of British Columbia via a highway and a railway through the Rocky Mountains. Since the 1960s, growth has slowed, but the area population has increased.
