The Ironworkers Memorial Second Narrows Crossing, also called the Ironworkers Memorial Bridge and Second Narrows Bridge, is the second bridge constructed at the Second (east) Narrows of Burrard Inlet in Vancouver, British Columbia, Canada. Originally named the Second Narrows Bridge, it connects Vancouver to the North Shore of Burrard Inlet, which includes the District of North Vancouver, the City of North Vancouver, and West Vancouver. It was constructed adjacent to the older Second Narrows Bridge, which is now exclusively a rail bridge. Its construction, from 1956 to 1960, was marred by a multi-death collapse on June 17, 1958. The First Narrows Bridge, better known as Lions Gate Bridge, crosses Burrard Inlet about 8 kilometres (5.0 mi) west of the Second Narrows.

Burrard Inlet is a shallow-sided fjord in the northwestern Lower Mainland, British Columbia, Canada. Formed during the last Ice Age, it separates the City of Vancouver and the rest of the lowland Burrard Peninsula to the south from the coastal slopes of the North Shore Mountains, which span West Vancouver and the City and District of North Vancouver to the north.
