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 is billed as North America's first extradosed bridge.^[2]

The bridge also has a dedicated pedestrian and bicycle pathway underneath one of its wings.^[3]
