Was P Diddy on the bridge at the time?

Beautiful. I wonder if the replacement bridge will be the same design?

[Copper]

It looks fragile.

We need something to inspire confidence

Also seen on Twitter: Biden says that the US Government will cover the cost of rebuilding the bridge and all other damage.

Why?

Doesn't the owner carry insurance?

By way of comparison, when the train derailed in East Palestine, he said that Norfolk Southern should pay for the cleanup.

What is the comparative hit to jobs, commerce and transportation?

You do know this completely fucked all harbor tunnel traffic basically forever, right?

Why do you say that?

I will admit when I saw the news originally I thought to myself that my next couple of DC trips will definitely be flights.

3600 trucks crossed the bridge daily. Many of those trucks are Hazmat. They now have to take a massive detour because they can't use the tunnels.

As for everyone else, in addition to losing the bridge to get to Dundalk and Essex, those trucks now have 30 or so miles of mixing in with the other traffic.

This is going to fuck the port, the state, the city and I-95 for a long while.

A widely circulated video of the Key Bridge failure drew attention to the disastrous collapse of the upper bridge structure. But engineers who reviewed the footage said that did not appear to be the culprit in the disaster. Instead, they said, the superstructure failure was most likely a secondary effect of the pier crumbling beneath it after the collision.

Engineers who reviewed images of the bridge both before and after the collapse said no significant fender structures were visible. Only fairly small structures were visible in photos taken at the foot of the pier, and they did not appear to be substantial enough to be able to stop a large ship, some of them said. They said the structures may have served another purpose entirely — like preventing water from scouring and undermining the pier’s foundation.

Benjamin W. Schafer, a professor of engineering at Johns Hopkins University, said, after looking at images of the bridge taken before the disaster, “If you zoom further out, you can see these large cylinders that sort of define the shipping channel. They are to direct the ships and they are part of the bridge structure. Some would say those are protective structures. But I haven’t seen any evidence of fenders myself.”

In some bridges, engineers may elect, instead of fendering, “the alternative of making the pier exceptionally strong,” said Shankar Nair, a structural engineer with over half a century of experience who is a member of the National Academy of Engineering. But the visual evidence so far, he and others said, suggested that the pier was simply not strong enough to survive the collision.

The structure’s apparent vulnerability left some engineers dumbfounded.

“This is a huge shock,” Dr. Nair said. “A bridge of that size and importance should not collapse when hit by an errant vessel.”

From my visit to Baltimore, I recall the "Domino Sugars" sign but not the bridge. It's not until I see the "Domino" sign that it occurs to me, "wait, I have been there."

Yeah, and the best time to see it is at the same time of day this photo was taken.

This will also push more travelers onto the Acela and NE Express, possibly to capacity, which will create new challenges. The months that the port is down will add major stressors to a supply chain that is still recovering from 20-21. And that port was the last floater keeping that city from being completely flushed.

This would be a good time to have a ferry service.

Is it a city that should be flushed?

Yeah the traffic this summer will be extra sux0rs. Tunnel traffic jams, tons of traffic taking 95 or 695 alternate routes adding time and distance.

Other things I’ve thought of. Cruise ships, any stuck, but otherwise lots will have to change their port. Same with normal cargo ships, any stuck?

Then I think of the businesses along the highway route that’ll now have nearly zero customers. Sucks.
