Dunsmuir-Tunnel

The Dunsmuir Tunnel is a railway tunnel under the city center of Vancouver in Canada, which is traversed by two lines of the SkyTrain, the Expo Line and the Millennium Line. It is 1396 meters long, is six to 24 feet below the surface and has two stations, Burrard and Granville. The west portal is located half way between the Waterfront Station and the Burrard station, the eastern portal right next to the Station Stadium - Chinatown.

Was built the tunnel in 1932 by the Northern Construction Company. He joined originally the main line of the Canadian Pacific Railway on Burrard Inlet to the goods station at False Creek. The construction costs amounted to 1.6 million CAD. The eastern portal was then a little further south than today.

BC Transit, the predecessor of the transport company Translink, took over the tunnel in the early 1980s in order to use it for the SkyTrain route, which was built in the context of the World Exhibition Expo 86. The tunnel can only accommodate a single track, but has a large gauge. For this reason, the tunnel was rebuilt by the division in two planes so that it now takes two tracks superimposed.
