Featured on Mar 26, 2024 by Null: The Francis Scott Key bridge, an important part of the Baltimore-D.C. I-695 Beltway, has collapsed after being impacted by a Singaporean cargo ship manned by a crew of 22 Indians.

Give me a single incident where a ship collision caused the entire bridge to collapse, all i got is partial collapses, exactly what I was talking about.
Here just a few weeks ago a container ship collided with a bridge in china, only a partial collapse:

This is poor engineering.
Apparently it was Pajeets. Edit: Apparently the STANDARD CREW was Pajeets, but they had a local ... pilot? Captain? ... piloting them out of the area, which apparently is standard.(do we know if it was a sheeboon yet I haven't read the whole thread) crashing into the damn thing.
Decades. Not years. Decades. With them putting pork in at every single point they can.New bridge is going to cost 100X what the original cost and take years to build. Shit won't pay for itself amigo!
They haven't even got all the bodies out of the water yet.
It will be built by a chinese company, with chinese workers housed in barges to get around laws against importing illegal workers, using chinese steel because there is no more US steel production.Decades. Not years. Decades. With them putting pork in at every single point they can.
One thing some other countries have is a “fuck the bridge is gonna blow” emergency systems where they can shut down the bridge at a moment’s notice - alarms bellow and crossing guards go down and traffic no longer enters.Looks like they made at least some coms to the shore about losing propulsion and power.
No guy trust the expert. He's a true and honest ENGINEERING MAJORDali-Key collision

That Chinese container ship you reference is (1) empty and (2) much smaller.
Assuming that the empty Chinese container ship is approx 40m wide and 200m long, this means it's a medium sized container ship, and it's empty mass might be around 20,000 metric tonnes.
The Dali was a large container ship with a length of approx 300m and a width of 50m. It's empty mass would be in the ballpark of 50,000 metric tonnes and it's fully loaded mass might be around 400,000 metric tonnes.
400,000 metric tonnes / 20,000 metric tonnes = 20x
The Dali's mass could have been as much as twenty-fold (20x) higher than the Chinese ship you showed in the picture.
Thus the impact energy of the ship in the Dali crash could also have been as much as 20x higher assuming the impact speeds were the same.
The Dali was built in 2015. It grosses 95,000 tonnes (95,000x2,200 pounds). It's an average sized container ship that can carry up to 10,000 container units. If they're 20-foot containers they can weigh anywhere from 4,000-5,000 pounds empty and up to 20,000 pounds full. I don't know if the 95,000 tonnes is empty or fully loaded. 95,000 tonnes is 209,000,000 poundsDali-Key collision

That's about what this guy says as well:Mildly educated opinion on this.
I've watched the video like 20 times. Ship loses the plant. Looks like the vessel is lined up to pass under the center span of the bridge before loss of power. Thirty seconds after power loss either plant is restored or the EDG finally trips. Vessel goes full astern (black exhaust out the stack means she's really pushing it) and the ship begins turning to the right.
Why? Because a standard propeller backs to the left, turning the bow to starboard.
If I were making a guess, I'd say the accident was caused not just by a loss of power but also likely a poor response from the conning officer. While I like "oh shit dump it" commands as much as the next guy, I think this was probably the cause of the vessel veering and ultimately the allision.
But it was. Truss bridges are like that pretty much by design. Something breaks and the whole thing collapses. It was known around 20 years before that one was built.The bridge was built in 1972. It wasn't a flaw of design or maintenance,
Can we all agree that if the Bay Bridge is knocked down too, then obviously someone pissed off Posiedon in that region and we should start considering animal sacrifice?Also apparently boat traffic is starting to back up around the Bay Bridge to the south.
You forgot to mention the anchor was deployed and had already begun dragging, but yea that's a good video.That's about what this guy says as well:
Ship loses power, ship master panics and tries to reduce momentum by backing down the propeller, inadvertently turning the ship towards the bridge support.
