Which Canadian highway runs from the Atlantic to the Pacific?

Which Canadian highway runs from the Atlantic to the Pacific? The answer is the Trans-Canada Highway.

It is a transcontinental highway system crossing all ten Canadian provinces. Its main route links Victoria, British Columbia, on the Pacific coast, with St. John’s, Newfoundland and Labrador, on the Atlantic, although the route includes ferry connections because Canada’s easternmost island province is separated from the mainland.

The Trans-Canada Highway Act launched construction in 1950, and Prime Minister John Diefenbaker officially opened the highway in 1962. Work continued in some areas until 1971. The main route is among the world’s longest national highway systems, extending for roughly 7,800 kilometres.

A common mix-up is the Yellowhead Highway, which forms a major western branch and alternative transcontinental corridor but is not the standard answer to this question. The Alaska Highway, meanwhile, runs from British Columbia toward Alaska rather than coast to coast across Canada.
