#112 Canada

The Fraser Canyon is a stretch of the Fraser River where it descends rapidly through narrow rock gorges in the Coast Mountains en route from the Interior Plateau of British Columbia to the Fraser Valley. The Fraser Canyon Highway Tunnels were constructed from the spring of 1957 to 1963 as part of the Trans-Canada Highway project. There are seven tunnels in total, the shortest being about 57 metres; the longest, however, is about 610 metres and is one of North America's longest. They are situated between Yale and Boston Bar.
