No. It will still be named after a local hero. It will be the Freddie Gray Bridge.

How would you know? Settlement was sealed.

If one of those ships took out the Talmadge Bridge, that would save GDOT a ton in demo costs.

Those ships are usually single screw with slow speed main engines and a basic generator plant. My guess is they tripped the plant and lost steering. There's basically no chance the main engine would have shut down.
Does the main engine not power anything else? It sure seems like the engine went out because the black smoke coincides with the lights coming back on, assuming that’s the main engine?
On the gps tracker videos posted the ship is going down the center of the channel until they have issues when it veers. I guess an explaination is the torque from the prop steers the boat without steering?
If that’s the case though, could you not steer the boat with a reversed prop in the proper direction?

Wow...456 arrested in those riots for a rapist, and only one charged.
Meanwhile you have nutjobs who are foaming at the mouth to track down people who walked around inside the capital and jail them for decades.
ETA: I see some of those redditors are in this thread.
Hope you like your political prisoners soys!

How are you going to turn the prop without power?

I don't think there has been any legitimate speculation that the main was down. Given the reduction in speed shown on GPS it is almost certain the prop was turning and in reverse coinciding with the black smoke from the funnel. The issue seems to be without power (either the gen set(s) are down or there is an issue with the power grid) the rudder is unresponsive. Add to this the single screw arrangement means the torque for the screw will not stop the ship in a straight line. On top of that you have an anchor dropped, since it is attached to one side of the ship and not on the centerline if/when it catches it will rotate the ship.

The ship engine runs the prop. I'm assuming that's the only thing it does? Then you have a separate generator controlled rudder apparently.
Due to the torque of the prop rotation, props will pull a boat in the direction they are spinning.
The ship was headed straight down the channel until it got pretty close to the bridge. I'm assuming this turning point is when rudder was lost? So my assumption is the motor was still working pushing the boat but without rudder it was veering starboard.
Usually if you go in reverse, the prop will pull the bow of the boat the opposite direction.
So if forward was starboard I'd think you could go reverse and get some port steering back?
It may have been something else that steered the boat to starboard? Maybe the rudder was stuck? idk

Maybe the hard reverse by the captain is what actually steered the boat into the bridge?
Its odd to me as a laymen the ship basically veered starboard only. There wasn't any noticeable back and forth at all?
The ship was headed straight under the bridge. Lost something. And turned into the bridge. That's what I don't understand.
Seemingly if it just lost power and turned the motor into neutral, why would it have not just continued on straight under the bridge?

I want to look at some of our bridges. I would think there would be a crash barrier between the bridge supports and a ship. These bridge supports don’t seem to have any barriers. Has anybody brought that up?

The circular structure in the bottom right/middle right of the photo is the "barrier" to help avoid striking the bridge. The problem is the ship lost power and took a path that wouldn't have hit those structures. And they weren't going to stop it from hitting the bridge. There is enough clearance on both sides for a ship of that size to go through without issue under normal circumstances.

Dang, pretty fascinating video.

pics really show how massive these bridges are. bridge beams make the cargo containers look like Lego blocks.

If you lose everything as in the ship goes dark, you don't have the propeller or the rudder.
Are these not separate systems? I'm curious how you would lose everything? I'd think on a decently modern system there would be some redundancy built in? Separate fuel supply, fuel system, electrical breakers, etc?
If you lose power to control the rudder it doesn't go into like a neutral and all rudder is lost? I guess its like a hydraulic type system and just gets stuck in place? I'd assume there's a way to manually do this but it takes time.
