The Ironworkers Memorial Second Narrows Crossing (Eng. about the transition of the second bottleneck in memory of the iron workers) is a six-lane highway bridge in the Canadian province of British Columbia. It connects Vancouver with North Vancouver, crossing the Burrard Inlet, at the second bottleneck of this fjord.

Eighteen of them were killed because they were torn in depth because of their heavy tool belt. Later, a diver who was searching for the bodies of drowned. A commission of inquiry came to the conclusion that human error was the cause of the accident. An engineer who was also among the casualties had, a calculation is performed wrong and underestimated the weight of the building material. As a construction crane swung around to insert an element, the bridge could not hold the extra weight and collapsed.
