    on local talk radio a few days ago was a statement from ODOT that the bridge repair date is indefinite as the steel material to rebuild the structure does not exist and there's a redesign issue.

      Aren't those girders custom-built in most cases? There's bound to be an allowance for the time needed to manufacture them. Any changes to the original design just adds to the delay- I'd be interested to learn what changes they deem necessary.

    Many times, birds nest in/on the bridge beams when they are exposed. There may have been having an issue with bird droppings on the playground. That may be the reason for the black mesh under the bridge, it may not have been an issue coming from the bridge but caused by the bridge.

    Casey… the radio station I listen to out of Cincinnati is doing these fake advertisements as a solution to beat the traffic across the Ohio River. It’s called Bob’s Bass Boat Transport. In the add they offer a premium service that includes a seat cushion and a free cup of coffee!😂 it’s not the most well written thing I’ve ever heard but it works for my twisted sense of humor.

    I saw your interview on TV. I have heard nothing about delays in getting materials, but that is not a surprise as the local channels are the last to hear anything. The local homeless shelter rep was advising people not to jump to conclusions about the source of the fire being the homeless. The longer the fire investigation takes, the more crap you will hear. Thanks for reporting on this bridge. Since the bridge connects Northern KY with Ohio I wonder what role KY has in this project?

    • @CaseyJones-Engineer
      @CaseyJones-Engineer  15 วันที่ผ่านมา +1

      Thank you. My guess is that KY's role is informal. I think the repair work would progress better under KYTC leadership versus that of ODOT based upon what I have seen so far.

      Since the span is completely on the Ohio side, Kentucky wouldn't have much to do with the repair. There is coordination with traffic control (left-lane restriction), but that lane was already closed due to work being done before the fire.

    Hey been enjoying the updates, 471 is my daily commute to UC and it's good to finally see some progress. I've been watching your channel for a few years and I know you mostly evaluate failed projects and how to fix/ rebuild. Have you looked at the documents for the brence Spence companion bridge also in Cincinnat? It's a pretty cool project and to see the improved design of the spaghetti of roads on the western side of the city. It's even going to free up about 2 blocks of space without demolishing much of anything!

    It would appear from your drone footage and from the street view of Google maps that these girders extend over the piers and that there are rivited/bolted connections in at least the next span south which would explain the falsework to support the next girder south (towards the river. There is a similar connect over the sidewalk at the roadway under the span over the roadway. The street view indication on Google maps is mislocated so it is hard to tell. But assuming that this is a situation of a continuous girder design it may well explain the additional falsework to support the cantilever sections of the adjoining girders when these are removed. Your drone footage may show this more clearly as it is where I notices the splices. Excellent footage, love to see more.

    Getting up there in age?
    I believe the Big Mac is the newest of the bridges in Cincinnati going over the river. The Brent Spence, the Clay Wade Bailey, and the Roebling bridge are all much older.
    Are they going to remove everything and then start reconstruction, or will they replace the exposed girders first and remove the remaining girders after the first four replacements are installed?

    • @CaseyJones-Engineer
      @CaseyJones-Engineer  15 วันที่ผ่านมา

    @ToxiCom-777 14 วันที่ผ่านมา

    At 2:00 in, the close-up of the not entirely all burned playground debris, there appear to be several metal beams that are not wilted. I'm wondering how non-structural steel (and in fact probably much lesser strength / much lower quality metal) survived without any bending or wilting whatsoever, versus American-made structural steel, likely best-in-world, was somehow caused to wilt from the top down, what, one-hundred feet above. Lots of evidence from this event fails to make coherent sense. What if the playground fire were secondary, like a diversion? Anything could have been hidden inside those black screens / curtains, for example. Or maybe there is something to the energy beam ray theory?

  • @ToxiCom-777
    @ToxiCom-777 14 วันที่ผ่านมา

    The wilted beams are drooping more from the top than the bottom. Being closer to fire (if the fire was indeed responsible for the wilting), the bottoms would have drooped more, like a candle melted from fire below. Instead, it seems as if an energy source (like maybe a beam weapon?) that caused the tops of the beams to melt first (and more) was in fact above the beams. Yes?

    • @ToxiCom-777
      @ToxiCom-777 14 วันที่ผ่านมา

      Also, it's peculiar how narrow and defined is the area of wilting. You'd think that the heat (if from fire) would be spread broader, giving much more even curvature to the wilt; instead, the wilting appears to have been caused by a localized heating, as if from beam weapon rather than open-air fire one hundred feet below...just another thought.

    • @kevins.3573
      @kevins.3573 13 วันที่ผ่านมา +1

      heat rises and was trapped under the concrete, heating the concrete, creating an oven at the top of the beam. While cold air was able to flow along the bottom of the beams as the smoke escaped.
      You should give your brain a rest after that comment.

      @ToxiCom-777 12 วันที่ผ่านมา

      @@kevins.3573 Video shows the flames were more prevalent at the outer edge of the bridge, not the inner edge. Yet the inner edge has the two noticeably drooping wilted beams. Moreover, the innermost drooping/wilted beam is itself an outer edge, though it is at the inner area air-gap between the two sections of travel lanes. By your reasoning, the air-gap should have kept Beam #4 (innermost) from drooping/wilting at all because the heat was not trapped but could escape up between the two sections. Also, your reasoning fails to account for the absence of drooping / wilting on beams #2 and #1 despite appearing in video as having more flames applied more of the time, thus trapping more heat. How do you account for zero drooping / wilting of beams #2 and #1 versus beams #3 and #4 ?

  • @paintnamer6403

    • @jpdemer5
      @jpdemer5 15 วันที่ผ่านมา +1

      Is there lead in the old paint? Maybe that was a concern, in view of the playground beneath. Keeping pigeons from nesting is another distinct possibility.
      In any event, I doubt that the netting contributed much heat to the fire - it would have burned off in minutes. It was the several tons of plastics burning below that made the fire so intense and long-lasting - a lesson for other cities trying to put such land to good use.
