Glacier National Park (Canada) [SEP] Connaught Tunnel and the Trans-Canada Highway
The Connaught Tunnel opened in 1916. The new tunnel bypassed Glacier House's siding, and the resulting lack of rail passengers spelled the end for the once-popular hotel. It was closed in 1925, and torn down four years later. The park saw few visitors besides campers from the Alpine Club of Canada's summer camps for the next thirty years. Until this point, automobile travellers crossing the Columbia Mountains had to use the circuitous Big Bend Highway, which followed the upper reaches of the Columbia River north in a large loop. With the planned inundation of much of that valley by hydro projects outlined in the Columbia River Treaty, a new highway route was needed.
