50 cars in the river
20-30 workers on the bridge at the time.
Im guessing the resurfacing work vribrations caused a damaged failing critical steel connections near one of the river pylons. The entire bridge did not unzip, it collapsed in almost one piece. Connection failure.
Bridge built in 1967,
single span?,
64 ft above the water.
If our house be on fire, without inquiring whether it was fired from within or without, we must try to extinguish it.
