Francis Scott Key Bridge collapse in Baltimore...

One thing they said on the news yesterday answered a question I wondered

How could a bridge not be built to withstand a potential collision?

They said that it was, when it was built in the 70s

Cargo ships are so much bigger, heavier and faster than they were then

They said this ship was over 100K tons going about 8 knots

They also said that the anchor was deployed but the ship was going so fast at that point it just would have dragged along and not done anything to stop or slow the ship down
