Ironworkers Memorial Second Narrows Crossing

Structure and characteristics

The crossing is a steel bridge with long, heavy spans designed to clear a busy shipping channel. During construction, an arch-like central section and connecting chords were assembled over the water; cranes and temporary supports were used to join the two halves. The site required substantial marine and shore-based work to place piers and erect the steel elements, typical of mid-20th-century large-span bridge projects.

Construction, collapse and casualties

Work on the bridge began in 1957. On June 17, 1958, as workers and equipment were maneuvering to close the central section, a catastrophic failure occurred. A crane that was extending across the gap caused several spans to collapse, sending many workers into the water. Seventy-nine men fell about 30 metres (roughly 100 feet) into the inlet. Eighteen workers died either at the scene or shortly afterward; when a diver later lost his life while searching for victims, the total number of fatalities reached nineteen.

• Date of collapse: June 17, 1958.
• Workers who fell: 79.
• Fatalities: 19 (including one diver).

Completion, opening and renaming

Despite the tragedy, construction continued and the bridge was completed and opened on August 25, 1960. In recognition of the lives lost and the contribution of construction workers, the bridge was officially renamed the Ironworkers Memorial Second Narrows Crossing in 1994. The new name honors those who died and serves as a reminder of the human cost sometimes paid during large infrastructure projects.

Importance and legacy

The crossing remains a vital artery for the region’s transportation network, supporting commuting, commerce and marine navigation beneath it. The event of 1958 had lasting effects beyond the immediate loss of life: it influenced workplace safety awareness, emergency response practices on marine construction sites, and the public memory of industrial risk. Memorial ceremonies and plaques near the bridge commemorate the workers and maintain public recognition of the incident's significance.
