I'm amazed that they would move the stargate out in the open like this.

Good thing there is a flashing light on this convoy, otherwise might be hard to spot and avoid. Not much time to get out of the way either. Safety team nailed it.

Now that’s engineering on both parts, the truck for being able to pull that load and the bridge for flexing and not collapsing under it. Nice vid👍

The great thing about tripods is they keep the image still.

Go to 6:30 and press the "J" and "L" keys to see the bridge deform. The "J" and "L" keys move the video by ten seconds and the deformations are more apparent with that kind of jumping.

pause it and play it again as it comes over the hump watch the railings on the right and the top beams unbelievable..!Nice video thanks.

Nice video. In around 1975 I worked for Hoffman , Belleville NJ and was on the team that moved loads up to 900tons. We placed nuclear pressure vessels in containment domes. Transported from barge that had a 1000ton electric hoist for transfer from barge to our vehicle. The tractor was a converted 60yard mine hauler w/5th wheel . We didn’t travel fast but production at the site stood still to watch 900ton go up the haul road to the containment bldg. If you are Jimmy Hoffman and reading this, thank you for the experience!

You can see it very well if you use your right and left arrow keys to move forward and back in 5 second increments.

At about 7 minutes, they go across. That was impressive to watch on MANY levels!

I Was An Equipment Operator Building That Bridge In 1989.

That’s what you call crazy. Putting a lot of faith with that much weight into bridges built by the lowest bidder🤨

Sweet! Looks like my fleshlight has been shipped.

My company fabricated and erected the bridge So some of the welds were mine

In a Hanna-Barbera version a butterfly would land on the anode and the bridge would collapse.

Hats off to the drivers!! Great job!!🤗

Incredible! Those guys that drive those oversize loads have some serious balls! Its cool how the guy in the back steers the trailer and they have an additional truck to help push it along.

So, how did your Mother-in-law enjoy the trip?

I really did expect the bridge to flex, I did not notice anything visually. Either way it was a very dangerous crossing.

Starting at 6:00 watch the white line on the right side. Around 6:20 and as the camera pans out you can see how flat the bridge gets. This is in response to all the comments below that said they couldn't see it. Hope this helps

Thanks for the comments. I'm surprised that I didn't have any competition for that location! I wasn't the first with a camera to arrive on scene, but no one else really saw the potential of this spot. I felt lucky to get this vantage point.

Wow, you can see the bridge flexing quite a bit.

I worked at a shop that shipped with heavy haulers. Always amazed me the loads they could move. Biggest job we ever shipped had 96 wheels under it. Through the city streets of St Louis.

I was in New York State on an Interstate Highway. They stopped all traffic, and had us tune to an AM Station. They were bringing a heavy piece of equipment across the bridge, but I didn’t understand why all these vehicles were parked on the bridge. Then the Load came across in headed towards me, going in the opposite direction. I’m guessing the vehicles were being used as a ballast. It was a huge truck like this one. It was equipment for a power plant, and that was just part of the equipment. BTW One of the scariest bridges I’ve been across, because you don’t even see the bottom, under the bridge. The trees looked like toys for a train set.

What the hell did I just spend 8 minutes of my life staring at?

I couldn't see anything. Maybe put a time stamp on where it flexes under the weight.

I enjoyed the guy steering in the back ... "do'n the Princess wave"

This is what I use when I have trouble falling asleep. Works like a charm! Zzzzzz good night everyone 😴

Pats bridge engineer on back “Well done mate”

This video stops before the shit really hits the fan, when my mother-in-law tries to cross.

Aaaand the next car, a Lada, sent the bridge into the water, killing a school of lake trout. so tragic.

I took my sons for a drive over that bridge, pretty scenic area. We weren’t driving anything like these vehicles, but we did drive some gravel backroads to get there. Wouldn’t want to be driving behind that mammoth load. Thanks for the interesting video.

thats INSANE.. I see the bridge flatten out. very scary, hope the structure is solid on that whole section. big trouble if not. pucker factor is way up. nice video thanks for sharing!

Even on this normally speed version of the video you can clearly see the bridge flexing under that load. Wow!!!

This video was almost as exciting as the one i just watched about paint drying. Next im going to watch a video of old people sitting on park benches. Fuck i need to get a life!

Thank you. Yes, it was really neat watching these KW's handle this load.

It takes skill and nerves of steel to do that job. I drive truck and pull a flatbed but that doesn't even compare to something like this. I give these drivers and pilots all the respect.

and that my friends is the reason they have bridge laws and heavy haulers to understand them. You don't just go out and buy a truck and do this. There is a lot of engineering that goes into spec'ing the truck for it's use. Getting the right drive train is the key. A regular over the road truck is not capable of doing these tasks. You have to have an engine, transmission, clutch and axles that will sustain the torque when starting from a dead stop as well as having suspension and tires to handle the weight. KW is by far the best truck and company for building these trucks. Some of these trucks take a year to get delivered since the components are built for the specific truck and customer. And yes, there is a huge pucker factor when crossing bridges. I totally enjoyed this video. My hat's off to the engineers and contractors of the roadways as well.

The miracle of steel... No, I meant the balls those drivers had.

I'm impressed with the truck. It has 2 people stirring it. Plus it is an amazing piece of equipment.

Thanks for that! That was a white knuckle rider for me....such respect for those load movers!

You can easily see the bridge "flex", by watching the K-Barrier Siderail as the load passes over the top of the structural arch!

My wifes hula hoop has arrived.

And that's why I love the art of structures. Architects can build their own empires that will outlast us all.

10 minutes of my life I will never get back.

Wow, I would have been so nervous crossing with that load...

Well I guess thats one way to make sure someone did their job in the bridge engineering department.

I think the driver is a righteous dude!

Well done! Excellent positioning to show the load deforming the bridge. Glad he was centered to distribute the load evenly.

Skip between 5:44 and 6:09 and you will notice the difference in the walls.

I could not see any flexing happening, but maybe that was because they were moving slow per their procedures.

Congrats to the engineers and construction crew of this bridge...👏🏼

Thanks for watching them.

When San Francisco had an anniversary party on (75th) the Golden Gate bridge it had so many pedestrians, the bridge roadway arch had flexed flat. They had to close any more people on the bridge. .It had exceeded the weight limit and could have possibly had a failure ( collapse) of the roadway. So as in the Conan movie: What is stronger, flesh or steel?!!

Riveting... is what held that bridge together...

Professional, precision driving and a beautiful thing to see.

ok i saw it after following the link in the description, looks like it functioned exactly as designed too, strong enough to bend without breaking, thanks!

And get this, this was the first "heavy" load to test the new Hoover Dam Bypass Bridge at around 900 feet above the Colorado River! It would've been neat to see how much deflection there was while crossing that. Not as dramatic as here, but still, I would've liked to have seen it.

To save strain and wear on the motor and transmission and to decrease that litre-per-meter figure; Just flatten out the hills you are climbing. Genius!

Thanks. You can tell I'm no engineer, but I do enjoy watching what they've figured out.

I've crossed that bridge many times and am glad I hadn't seen this video. Next time I'm there I'm going to take a closer look at the bridge and not the lake. Amazing that the concrete flexed that much. There must be cracks.

I think I need a lie down after all that excitement

Well, it's a good thing the bridge has some flex in it, so it isn't likely to get stress fractures as easily. Still, one truck doing it to that extent is pretty crazy.

@ 9.35 I bet the people in the boat in the lake were scratching their heads when they saw this bad boy crossing the bridge, congras. to the person that recorded the whole scene or the transportations of that equipment... nicely done.....

To make it easier to see just switch from 6:59 to 7:28 and go back and forth between those times. You can see the bridge buckle if you skip between those times.

Not saying it didn't flex but I could not see it.

Video starts at 5:00

I don't remember which video it's in, but I have a clip of this load clipping along at maybe 45 mph. The road conditions didn't allow very much of that though. Thanks for watching.

Amazing how much the railing deforms when the load is in the middle of the bridge - presumably this did not permanently deform the suspension cables. Loved the hawk fly by around 4:45.

Would have been great if the guy didn't have to move the camera every 5 seconds.

where they delivering the stargate?

That's cool to see how the concrete starts to flatten out. thanks for the video

I drove a flag car for years and you have to tip your hats to the men that drive these trucks. It takes amazing skill to drive these things to the places they have to go. Some of these loads are so big you have to have a second person steer the back of the truck. Amazing what these guys do. Bridges are scary but I bet he drove through things you couldn't believe just to get to the bridge

Pretty cool. You can’t see the road flex, you have to watch the railings and you will see it. I used to have a roommate who worked for a company that arranged for escort vehicles for stuff like this. I kept hearing “do you need a pole?” (You can see one on the lead vehicle) and wondered how you could do a road survey for something this size to ensure the roads could handle the weight.

I LOVED watching the deflection, as viewed at the railings on the sides. Judging from those, it looked like considerably less than a foot of deflection. Estimating a 48-foot span, the max allowable deflection would have been 1/240th of that, or 0.2 feet = 2.4 inches. That looked about right. The height of the railing staves was probably 24", and it looked like about 1/10th of each stave was the max that it moved down. BTW, the load did not put a permanent flat spot on the bridge. It "un-deflected" as soon as the load was removed. Long, long, long ago, I worked in a consulting engineering firm designing the I-55/I-70/I-44 bridge over the Mississippi River at St Louis. I was very young then, and new to it all. And it was the only bridge I ever worked on though I worked in engineering for over 40 years. My bosses told me that ALL US bridges at that time were designed with a Safety Factor of EIGHT. The steel used is ASTM A-36 structural steel with a rating of 66,000 psi. This means that the steel USED is designed as if the rating is 1/8 of that - or about 8,250 maximum stress on the steel. So, basically, with a S.F. of 8.0, the load for 285 tons (570,000 pounds) it is as if a NORMAL building-type structure designed for 18,000 psi (a S.F. of 3.67) was seeing a load of 130 tons. A big deal and not a big deal. Moving big stuff like that is ass-kicking. I once had one of my brand-new double-width 120" industrial fan rotors get destroyed, clipping the underside of a bridge that the truck driver shouldn't have been going under. My company was not pleased!

Thats a nice modern bridge. I wish we had that bridge right now in West Seattle. Our massive bridge is actually crumbling and closed to the general public for major repair work. That 285 ton load the trucker is so carefully pulling would probably cause our poor old West Seattle bridge to collapse into the Nisqually river below. Nice driving guys!

Prescision Heavy Haul of Phoenix did the move.

literally watched the bridge flatten with the bearing weight

Nicely done!! Great video!! Yes sure can see the bridge flatten out.

Man that was amazing !!! I'm still shaking.

285 tons? Not often you see a moving object heavier than a Maus Tank.

Wow that camera has one hell of a zoom on it?Great video.

I've been on railroad bridges when heavy trains crossed. It's pretty wild to feel the bridge move under you and see huge girders flexing under the load.

Thank you for posting this.

thats a trail king trailer...i mightve helped build that1

Wow is it just me or does anyone else see a moving ripple in the walls of the bridge as the truck passed over

For those who stated that they cannot see the flattening of the arch go to 3.47 and note the roundness of the top of the arch represented by the concrete, at the bottom right hand corner and then go to 6.23 and you see the difference showing a good amount of flattening,

Nice job on that clip...setting up for the staight on and then the pan. Well done. Thanks for posting.

That really says something about the load this bridge carried that day. That whole set up stretched 225 feet, and it still put a noticeable flat spot in the bridge! That said, I really doubt that the engineers that crunched the numbers and inspected the bridge before the move were sweating very much. If it were very close to the limit, I suspect they would've changed the route or the trailer requirements.

I bet the guy running the tiny steering wheel makes the most...

Holy cow! That thing flexed a lot

wow my head just hit my desk this video puts to sleep then wakes you up

I’m not buying that the load was 570,000 lbs.

Most people only need to bring along a spare tire. These guys bring along a spare truck.

The bridge clearly flexes downward about 6" as the load passes over. Focus on the vegetation in the background just above the fence along the edge of the roadway and increase the speed of the video two times and you will easily notice the flex. Nice video.

I drove a 41 ton load over a 9 ton limit bridge. The next day the sign was inverted to 6 ton limit. The central support was stone work. The bridge was about 70 feet long and 15 feet above the river. This was in 1980. A year later they put in a new one.

Weird flex, but ok...

I'm surprised there is no flatearther arguing in the comments that it's refraction those flatheads don't like anything that is related to some sort of curve.

Because it's one the most amazing videos ever!

I saw this once before. In 1987, it was the 50th anniversary of San Francisco's Golden Gate Bridge. The bridge was closed to vehicles so that 1 million pedestrians could walk across the bridge. The weight of all those people was so heavy that the natural arch of the bridge flattened to a straight line. I'm surprised it didn't collapse.
