The bridge collapsed early in the morning when one of its concrete slabs fell due to a failure of the suspension structure. This structural failure was caused by improper welding of the steel trusses of the suspension structure beneath the concrete slab roadway.
In the accident 32 people died and 17 were injured. Afterwards, the bridge was supposed to be repaired, but because of a weakness in the structure, it had to be completely redesigned and rebuilt. The new design was finished on 15 August 1997, and is similar to the original design.
