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.
Directd Enrgy Weapons have been shown to do that kind of wilting. I've been thinking that maybe the "fire" is a cover story. What do they call it, disaster capitalism, with manufactured disasters.
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. Anyway. I’m glad you’re on this story. Something tells me it’s gonna get worse before it gets better
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?
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.
In the Uk it would take three months just to do the enviromental impact report. before they could look at the bridge. Then planning permiission a year or two. You have got it easy.
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 looks like they could have moved the playground incendiary structures in the open areas next to the bridge and put the parking area under the bridge. At least that would be less burnable material to harm the bridge.
@@kevins.3573 And something like a Cybertruck fire that spread to other vehicles would be a disaster. Look at the Fremantle Highway fire, or the Grande Costa D’Avorio, or the Felicity Ace.
15 or 20 years ago their was similar damage to I-580 in Oakland CA that was repaired in record time. It might be interested to do a deep dive on that repair project as a contrast to this and other similar longer lead time projects.
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?
Having driven over all four, the Big Mac seems to be in much better shape than the others. The Roebling bridge, in particular, is quite hair-raising. Thoughts about the question i added above?
@@CaseyJones-Engineer If the overpass was already failing, they should have chosen another area to put the playground instead of putting the net...or was the playground already there when the bridge was built (it did look like a very old and outdated playground). Well, you know what they say about hindsight. This may very well turn out to be a study case of why you may not find playgrounds under bridges in the future.
When the falsework towers are installed, are they jacked or shimmed to load them in compression so they don't shift when the beams are cut and the beams' weight is transferred to the falsework?
I am curious about the affect on the subsoil underneath the playground and surrounding area for the drainage and possibly erosion under the N around the bridge pilings?
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?
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?
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.
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.
@@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 ?
Maybe the underside netting was also to prevent toys, rocks etc from getting stuck or resting on the beams only to fall at a later time from traffic vibration.
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.
The damage doesn’t look as bad now that the decking is removed. They definitely got over heated but some look like they could be tested to see if reusable. But that would take to much time
In a way this is like the PEPCON disaster where they stored the rocket fuel in plastic and aluminum barrels at the factory. The final fuel mix required the fuel in a rubbery plastic matrix with aluminum catalyst. 🤔. When a welders spark hit something they had all the ingredients
PEPCON was one of the initial Dir Energy Weapons tests. The impact of the explosion is really an implosion. Steel pipes underground were melted some distance from the plant. Plant made rocket fuel, was a competitor to Dick Cheney's HALLIBURTON. Cheney's company went on to take over the rocket fuel production. Whole theory about the scalar weaponry aspect, as described by Col THOMAS BEARDEN on the DUTCHSINSE channel (and other places).
That bridge was torched. Where's the investigation? Maybe call Rozzi are they missing a giant sparkler. This was sabatoge like the truck a few years back. Dorkwine strikes again
Yep. Its been total silence about the cause. There was one video from a camera a block away, something went up like a giant flare and then everything else was secondary. I am curious if it was intentional or possibly a large electric vehicle battery that went off. No reports that ive seen though.
Do you think the "PARK DISTRICT " carries an insurance policy commensurate with the value of the damages that their GO GREEN wonderful playground fire did to the bridge!! I'm being sarcastic.
When will the FHWA stop states from storing or building flammable materials/structures under highway bridges? This is so unnecessary risk for these critical infrastructure items.
Maybe it's time to consider fencing under all bridges to prevent trash, playgrounds, parked cars, or homeless people from starting these destructive fires. The repair costs are in the $$ Millions!! Not to mention the dangers of collapsing roadways and months-long impact to traffic.
@@kenpryor4440 A better question is why the playground structures are so flammable. Ye olde steel monkey bars and swing sets with steel chains would not have done this.

Not a playground, it was a playgroung shaped improvised incindiary device.

@@steveo4749 Unless you have a car fire. In that circumstance putting a couple dozen 20 gallon cans of gas under the bridge might bite you.

@@PaulSteMarie I suspect they will remove the deck and girders in their entirety in the damaged section first.
Thanks! Great videos!
I bet the mesh was for pigeon droppings.
Good point. Although ODOT has said that the netting was to hold concrete debris falling off the bridge per WCPO's report.

Even though they are not the same , this is going much better than the RI bridge.
I agree. RiDOT is not even in the same league.
Hey hey hey!! What's this "getting up there in age"? I was completed in 1976.
🤣
Could the mesh be a bird/pigeon protector, and to prevent their waste from falling onto the playground?
The damage doesn’t look as bad now that the decking is removed. They definitely got over heated but some look like they could be tested to see if reusable. But that would take to much time
Is pouring concrete in freezing temps a problem?
Surround it in scaffolding with plastic tarp and run heaters. Antifreeze can also be added to the mix.
The netting was likely part of a painting project. It's lead paint and they can't let it fall on that playground.
No temp shoring?
