S92 vs bridge, bridge wins
MechEngr - check the press images (eg the town mane in the green sign) and you’ll find it was travelling under the bridge from the opposite direction, where there is no height restriction sign on GSV (interesting from a potential court case point of view)
Also, another airframe waiting on an S92 rotor head, potentially- but the airframe damage may ace that in the insurance assessment as suggested in other posts

It amazes me that in this day and age there is not a radar sensor (akin to a parking sensor) on the top of all trucks , buses etc that scans ahead and shrieks if it sees a height hazard (in the case of a truck it would need to be programmed with the height of the load obviously).
Similarly - I'm surprised that bridges that have been hit multiple times are not fitted with a similar system that would flash big red lights and klaxons if it sees something too big coming towards it.

Most of those hitting the beam are drivers of rental vehicles who likely never before had a concern about vehicle height so they seem to have no idea that any warning might apply to them.
See https://11foot8.com/ for more entertainment. AFAIK I have seen only one injury crash which i attribute to failure to wear a seatbelt and the passenger finding the dashboard, which is sad. For the remainder - absolute agony to the wallet of the driver or owner of the vehicle and a powerful lesson to read signs warning of danger.
Established law, certainly in the UK, is the roads are "as you find them". It is up to drivers to negotiate them adequately. Advisory signs, and all the rest of the infrastructure provided, may be useful, but there is nothing incumbent on the highway authority to provide anything specific.

Ten years ago, an oversized load struck a 'fracture critical' through-truss design bridge on I-5 north of Seattle - causing the bridge to almost immediately collapse (the truck in question managed to make it off the bridge, but a few other vehicles were not so fortunate and fell into the water - fortunately without serious injury to the occupants).
Seems that the bridge had adequate clearance in the left lane, but not in the right lane - the (required) pilot car failed to notify the truck driver, and traffic in the left lane prevented the truck from moving into that lane.

Wrong, not Bristow
Wrong, not Bristow. I’m sure no one else ever used Blue on a helicopter. Since when does Bristow have a patent on Blue paint?
.
Looking at this photo it appears the trailer is straddling the "Fog Line" which is the right most travel lane marking. Anything to the outside of that is not considered a travel lane and height markings do not apply to the vertical space above the "breakdown lane" which is the paved surface to the outsides of the travel lanes.
When you obtain a Permit from the Louisiana DOT, there is a paragraph that frees the State from any liability and places all responsibility and liability upon the Permit Holder.
Skip down to page 17 and start your reading from there if you care to know what the Regulations have to say for oversized load operations in Louisiana.

SASless, after hitting the bridge he was moving to the shoulder but likely stopped due to the continuing sound of damage. The state won't be liable for these damages but the management of the DOTD are liable, independently, for failure to mark the overpass to the legislature that passed the laws requiring the overpass be marked, and will possibly get some hassle from the Feds for failure to comply with Federal highway requirements as that overpass is built, in part, with Federal funding.
whoknows idont, as I pointed out about the link to Google maps, one can get photos going back more than a decade; the sign has been missing since at least 2015, if not a few years earlier, but was there in 2011 when it was built. Living far north of Louisiana it is distracting to see the bridge has not been painted in 22 years, but then I realize they have not applied 22 tons of salt to de-ice that bridge in that same time. Up here that bridge would have some holes and been repainted to keep the rust in the shape of the bridge.

It's not a "fog line" (although those would come in handy in Louisiana) and it's not a breakdown lane or shoulder. It's a regular lane of travel. "Street View" it. The driver was headed westbound on I-12 and apparently got off there at Exit 10. I'm guessing that he was maybe headed to the Pilot truck stop which is just on the other side of that overpass on the right hand (west) side of that road. One of the "experts" on the JH board testifies that the ship is not from Bristow, nor is it SN92006. We are lucky that such pompous, self-proclaimed experts abound on the internet (although fortunately not many on *this* board).

While on break one day at Fedex, I decided to go to the local Indian Casino for a slice of pizza for lunch. I like to park in the garage, but wasn't sure if my cargo van would clear the entrance, so I went around back, and parked outside.
Seriously, being a truck driver isn't rocket science.

I just can’t imagine how hard it would have had to hit the bridge to do that much damage. Incredible.
I wonder if any settlement will take into account availability of a replacement, my understanding is there aren’t a lot of s-92 airframes available?
Very bad day for the truck driver..

There is a lot of energy in a tractor-trailer, probably 35,000 pounds going 40 mph. It didn't even seem to leave a mark on the bridge. There is a lot of leverage in a direction that I suspect won't happen except in a crash.
I saw the immediate aftermath of a bridge hit by a truck carrying a 40 foot long 12 foot diameter, 1/2" to 5/8" wall steel tube that stopped the entire truck, trailer, and steel tube in about 18 inches from 60 mph. It twisted the bottom flange of the steel beam 90 degrees. DOT had widened the bridge that crossed an up-sloping highway and failed to indicate the resulting loss of height. The second part of the plan was to deepen the highway cut by 12 inches, but too late for that driver. I got there just after the crash but later went on foot to examine the bridge and abandoned tube.
I just noticed the collision shoved the helicopter so that one main wheel is off the trailer and on the ground, so a good chance the nose gear is also demolished from use as a fore-aft restraint. There is the trough the curbside main is in, including a tie-down still in place, and it looks like a similar trough is on the street side, but there is no tie-down there. Not sure what to make of the distance from the street-side (port) main and the street-side trough.
Per https://louisianavoice.com/2023/09/22/32194/ there was also an escort vehicle, so great job all around. The escort is shown following in one of the photos. Article also suggests a fuel stop was the likely immediate goal.

Another angle from https://965kvki.com/ixp/29/p/helicop...iana-overpass/ showing the street-side main wheel far from the red cradle and the detached tie-down.
Ok , if you know who's is it ? The oil cooler cover is blue same as the Bristow scheme, Avinsis/Babcock/OSA as mentioned are white, may not be a current Bristow machine but looks to be in their scheme, other machines with upper Blue decks are Cougar and the old CHC scheme though don't think any old CHC schemes are around now.

questions from a lurker
would the write-off include the engines too (if they are installed)?
how much damage would the input shafts get from the MGB and quill shafts being ripped out?

"NOW that's what I call a Rotor Brake" 1
So FH tells us it was not ON an Interstate Highway....but rather was UNDER I-12.....thus State Route/USHighway Standards apply rather than Interstate Standards.
That makes a lot of difference...and instead of being westbound the truck would have been southbound on the secondary road headed towards the Pilot Truck stop.
That meant the truck would be passing underneath two sets of bridges going each way to/from I-12 and the Truck Stop.
Also mentions was the escort vehicle.....any mention of it h having a height pole installed and being used?
