WTF. Did anyone catch the news conference this morning and the news reporter from south of the border that asked the question what was being done to help the families of those brave men that died in the service of the country. I guess filling potholes now is some grand service to the country. So are they going to get a Ecuadorian or Honduran flag draped coffin ceremony?

Were the workers here legally or illegally? It seems germane if the Maryland DOT is hiring illegals for road work. I'm not suggesting they caused the accident, but it would be helpful to know if government contractors are violating the law.

The government is not just encouraging illegal immigration, they are assisting illegal immigration to such a degree that they are flying illegals from around the world, paying them indirectly (and in some cases directly) with your tax dollars to do so. I don't know where or how knowing the status of these people is helpful beyond curiosity sake and/or serving as a distraction. The Federal Government enforces or disregards "law" of all kinds with casual disregard, any and every time they want to, and if you question it effectively they will punish you (again with your own money) and/or imprison you at their discretion. |

They said the largest crane there can pick up a max of 1,000 tons. The piece of bridge laying on the ship they say weighs around 3,000 tons, so they are going to have to chop it up with torches and remove it piece by piece.

I figure the roadway sections will be the biggest pain in the ass part to move. I think the bridge truss system would weigh much less than the roadway sections. Plus the roadway is several materials all together, where as the truss neywork is just steel. |

Quote HistoryOriginally Posted By Dboy11: They are planning on the port being operational in 6 weeks Equipment is still inbound from all over the world for the effort Virginia ports started unloading vessels due to Baltimore last night. One of the bigger issues is a massive quantity of bulk agricultural products come into Baltimore and it’s the beginning of the planting season The weather has put a damper on towing stuff to the site, a few guys have lost some barges from tow ropes breaking, usual stuff Not sure about the New York side, but the Virginia ports have stepped up everything they can. It makes me proud to see what everyone is doing. Maryland is doing a great job getting things in place. Again, makes me proud to live in this great country. Keep crushing it. What's happening at the Richmond Marine terminal? They could probably use a shot in the arm. |

Once freed from all of the steel trusses I assume the ship will be pushed/pulled to a nearby terminal. Would the pier she came from be an option or will she go elsewhere due to the damage?

Would the pier she came from be an option or will she go elsewhere due to the damage? Just a guess, but they'll probably tow her to one of the ports upstream to unload her before sending her to wherever she goes from there -- shipyard to be fixed, or scrapyard to be taken apart, depending on how fixable she is. It's possible they'll have one of the cranes unload her where she is onto another ship (or barges), and then tow her directly to wherever she goes next. They aren't doing much of anything until they get the bridge off her, though. |

When you have that much material mangled like that, it can be hard to predict what will happen when you cut a piece….even more so when a significant portion is underwater and can’t be seen. Using cutting charges would let the workers be away from the mess when a section is “cut” away. I also don’t do this type of work, so I’m just guessing here. |

Something with that much size and mass, is probably like a widowmaker in felling. Could move in dangerous ways, when the load on one section is moved/removed. But I have zero experience with this, and don’t know what kind of material thicknesses they can work on, especially with sections underwater. |

I know nothing about this kind of recovery/cleanup stuff - but I would imagine that the best approach would be to FIRST use cranes and airbags and whatever else to get wreckage and debris out of the main channel as quickly as possible (maybe just dumping it on either side) and THEN clean up and remove all of that at a more leisurely pace later. With such an approach, I imagine the port could probably re-open to operations within three to four weeks.
Obviously, building a new bridge will take years, but I imagine the port can be operating again relatively quickly. That said, I would not be surprised if I am completely wrong, and it takes much longer.

Quote HistoryOriginally Posted By fox2008: It would also seem safer to me. When you have that much material mangled like that, it can be hard to predict what will happen when you cut a piece….even more so when a significant portion is underwater and can’t be seen. Using cutting charges would let the workers be away from the mess when a section is “cut” away. I also don’t do this type of work, so I’m just guessing here.

Det cord cutting charges seem like they would be more efficient/faster?? It would also seem safer to me.

Quote HistoryOriginally Posted By shooter_gregg: The roadbed may not be an immediate issue if they can remove the trusses. Channel bottoms tend to be soft, hence the need for regular dredging. It may have sunk into the mud deep enough to be below the subsurface. Anything sticking out of the mud can be lopped off. Clear the channel first, then the remainder as it is convenient/ necessary. Parts of it may never be removed unless economically advantageous. Seems like leaving road surface section would impact future dredging. |

Quote HistoryOriginally Posted By atavistic: Were the workers here legally or illegally? It seems germane if the Maryland DOT is hiring illegals for road work. I'm not suggesting they caused the accident, but it would be helpful to know if government contractors are violating the law. Lol. All they do is get an itin number and find a job as a "individual contractor". Companies at the top hire a contractor who hires contractors. The company at the top and the buyer of services just play dumb. |

Quote HistoryOriginally Posted By ArmyInfantryVet: I figure the roadway sections will be the biggest pain in the ass part to move. I think the bridge truss system would weigh much less than the roadway sections. Plus the roadway is several materials all together, where as the truss neywork is just steel.

I figure the roadway sections will be the biggest pain in the ass part to move. I think the bridge truss system would weigh much less than the roadway sections. Plus the roadway is several materials all together, where as the truss neywork is just steel. The roadway looked like it fell in chunks like lego blocks. Was this built using the pre-fab segment or built with 50' chunks of bridge at a time which were then sealed to the previous section? Those should be easy to pull up as chunks or airbag up on the ends since it's already in blocks maybe? The truss should be easy once cut. Hopefully they remove all of it. There was bridge over the Missouri that they demolished and left some of the truss on the bottom of 30' river channel thinking it would be a place for fish to hang out and no danger to boats which only need the top 5' of river. 40 years later, they run the spillway full tilt to avoid dam overflowing (~2011?). The next year my brother heads out to fish and the trusses of the old bridge got pushed into the channel, ripped the bottom end of his outboard clean off. He wasn't the only one. That's an expensive lesson, though the state didn't have to pay for the losses. The truss got moved about ½ mile downstream and almost straight out from the boat ramp. Just one chunk was sticking up to 2' below the water so it was invisible and missed by the lucky people and the others had their engines ripped up for no apparent reason. They did put up buoys the next weekday after several reports and divers cut it up to sit on the river bed no matter what future currents happen. I could just see them also cheaping out leaving the truss outside the channel lay there as is and eventually get pushed into the main channel removing 30' of draft. |
