Who is Leon Mosseiff?

Some of the suspender cables were damaged some not now their only value was.

What is the Scientific understanding?
When the bridge collapsed it formed this in the water.
What is an artificial reef?
When the wind hit the girders and separated it created alternating low pressure vortices on the top and bottom of the deck.
What is vortex shedding?
This was the person who captured the famous color footage of the construction and the collapse.
Who is Barney Elliott?
Due to this being excessively narrow it added even more flexibility and instability.
What is the deck?
The new bridge uses these so that the bridge is less flexible and more sturdy.
What are trusses?

What is scrap?
Just before the collapse this slipped causing the verticle wave motion to turn into a violent twisting and turning motion.
