Francis Keys bridge hit by ship. Bridge collapses, mass casualty event.

You don’t think money would help build a better bridge?
They could put safety pylons round the main supports, but if you ram 50,000 tons into anything it causes damage. Mass times velocity.

The pylons would have to be so big ships wouldn't be able to fit through the channel.

A bridge in a shipping channel is always a compromise between structural bulk and height/span to allow ships to pass under it.

I think they are designed to deflect away from the pylons.
 
As someone who has been on many sites, hard hats arent just for welders. They are for anyone on site in certain zones. If you worked for a living that wouldnt be a surprise. How are my social security contributions you are receiving from Uncle Sam treating you?
What in the fuck are you mumbling about? Welders don't wear a "hard hat".... they wear a "welding hood" or "welding helmet".

Why do you even bother? Your ignorance is embarrassing as fuck.


This is called a welding hood.

This is the Buttplug's hard hat....

Since the big companies keep demanding bigger and bigger ships be built, they need to make these all drawbridges of quit building them across ports.

Better yet, quit rewarding outsourcing and bring industry back here.

99.99999% of the time they work just fine. Drawbridges can only be certain sizes as well, and most major ships are too big for them.

So quit building bridges across heavily used waterways. No reason ports can't be built elsewhere and traffic patterns modernized.

Um, no, they can't. ports need to be near population centers for obvious reasons as well as deep water areas for the other obvious reason. Plus the whole Chesapeake bay area needs bridges as it's a massive collection of bays and peninsulas.
 
Every time I wake up there is a new tragedy.... where is buttplug edge edge?....
i'm sure the sec of transportation was on the deck, grabbing the wheel from the helmsman and aiming for the pylons.

more likely uninspected, foreign registered vessel crewed by unlicensed non union crew.
 
That ship weighs hundreds of thousands of tons, empty. There isn't a bridge in existence that could survive a trike by that that much weight, moving at 9 mph.
Actually, there are such bridges although they are fairly new.

The same thing happened to the Sunshine Skyway Bridge over Tampa Bay quite some years back. It was rebuilt with solid barriers to the pylons.
