If the bridge can’t take a bump from the traffic that goes underneath there should’ve been additional pylons or something just to prevent direct collisions like this
“Bump” is a galactically humble description of a collision with a container ship weighing nearly 200 million pounds.
To illustrate this more cleanly, the momentum of a loaded Boeing 787 flying near top speed is 17,760,000 N.s. For this ship going at just 10 km/h, the momentum is about 260,600,000 N.s. In other words, the bridge would need to be able to sustain the equivalent of 14 9/11 attacks, simultaneously.
The way to tolerate incidents like this is to add multiple points of isolated failure so that even if one point is catastrophically destroyed, only a portion of the bridge goes down while the rest remains intact. I don’t think there are many, if any, structures on the planet that can withstand that much force
This right here. You’d need a frankly ridiculous amount of solid stainless steel to build pylons for seaway protection, and that’s for low speed impacts.
Kinetic energy increases with the square of velocity!
I’m not a sailor it anything, but I suppose requiring tugboats for all harbor travel of shops over a gross weight might be a good thing. Makes more jobs, at least.
A container ship like that weighs more than the bridge tower it hit.

Saying the bridge was bumped by the cargo ship is like saying someone got bumped in the head after having a brick thrown at them.

That was hardly a bump.
