Excerpt from Wikipedia
The North Arm Bridge is an extradosed bridge in Metro Vancouver, British Columbia, Canada. It spans the north arm of the Fraser River, linking Vancouver to Richmond. It is used by trains on the Canada Line, which opened in August 2009.
The bridge also has a dedicated pedestrian and bicycle pathway underneath one of its wings, which was added by Translink at a cost of $10 million.
Bridge Details
The North Arm Bridge does not carry automotive vehicles, as the neighbouring Oak Street Bridge does. The bridge has two tracks enabling SkyTrain to pass each other either way traversing the bridge between Bridgeport Station in Richmond and Marine Drive Station in south Vancouver. The main span is 180 metres (591 ft) and has a total length of 562 m (1844 ft). The bridge deck elevation can go up to 25 metres (83 ft) while the maximum tower elevation is 47 metres (154 ft).
History
The bridge incurred one fatality during its construction. Andrew Slobodian died instantly on January 21, 2008 when the crane he was operating tipped over and he was crushed. A small plaque is installed in the middle of the bridge - close to where Mr. Slobodian died - recounting this event.
