Amazing that this bridge was built before A380s existed… but my DAD still wouldn’t drive under it when one rolls over

[-]

Fantastic_Egg949@reddit

This would make my week driving up and under this beauty 😍

[-]

Evilbred@reddit

I mean the bridge likely has a far higher load rating than the A380, elsewise it wouldn't be allowed.

[-]

Loud_Boysenberry_736@reddit

Elsewise is my new word of the day. Thanks!

And while I agree with your engineering reasoning, I wouldn’t drive under it with those nice planes going on it. I’d try to stop safely and appreciate the sight. Maybe even take a picture or two.

[-]

apatrol@reddit

Wouldn't be safe though. Stopping in a busy road while everyone watches the plane is a great way to get hit at 40mph.

Stoppimg is 99.99999999% more likely to cause injury than that plane

[-]

jeepfail@reddit

Been hit while at a standstill by someone going 40+, would not recommend.

[-]

flume@reddit

I'd wager it's significantly more than 100% tbh

[-]

apatrol@reddit

I didnt want some statistics dude find one plane that drove off a bridge and crushed a car.

[-]

jeppps@reddit

Don't worry in peak hour you're basically stopped anyway

[-]

Loud_Boysenberry_736@reddit

Agreed. That’s why I said stop safely. Maybe there’s an emergency lane or bay somewhere behind where the video starts.

[-]

Infinite-Condition41@reddit

Great, thanks for the fucking car accidents.

[-]

Multitronic@reddit

Don’t stop on motorways just to appreciate planes. They are already dangerous places.

[-]

aaronhayes26@reddit

Engineers are very fond of futureproofing when it comes to bridges. You don’t have to know the exact specs to know that planes in 50+ years could likely be extremely heavy.

Building a bridge that can hold twice as much weight as it currently needs to is a lot cheaper than having to rip it out and build a new one prematurely.

[-]

greenmachine11235@reddit

If engineers had our way, bridges wouldn't ever fail but those pesky accountants demand we keep costs down.

[-]

OldEquation@reddit

As a project manager, I will say that if engineers had their way the design would never be completed and all the money in the world wouldn’t be enough to pay for it.

[-]

mjsarfatti@reddit

As an engineer, this project manager is 100% right.

[-]

Traditional_Pair3292@reddit

The Brooklyn bridge was something like 400x overbuilt if I remember correctly.

[-]

ScottOld@reddit

I would say so, given big fat antanovs have been around longer

[-]

EvilSibling@reddit

Sydney Airport did make a number of modifications to accommodate the new A380, including strengthening this bridge, referred to as the General Holmes Drive Tunnel in this case study

https://tbhconsultancy.com/experience/a380-project/

[-]

viroseo7@reddit

It's pretty impressive that they actually reinforced existing infrastructure instead of building entirely new routes.

[-]

Maleficent_Sir_5225@reddit

Sydney doesn't really have the room for that.

[-]

Infinite-Condition41@reddit

It isnt the weight of the plane, it is the distribution of the weight.

Big plane, but lots more wheels. Probably has the same or very similar loads on the ground as a 737 with only 4 main tires.

Math check 737, 175,000 pounds, 6 tires, 29,000 lb/tire A380 1,268,000 pounds, 22 tires, 57,600 lb/tire.

A380 tires are 27% wider and 25% taller, making a larger contact patch, meaning the pressure per unit area on the ground is likely very similar.

And it would have to be, since airport runways and taxiways dont magically get stronger for bigger planes.

[-]

Evilbred@reddit

It depends on the design of the bridge.

Often time, loads are concentrated, in structural supports, especially so it could be the aggregate weight on the entire bridge.

[-]

Infinite-Condition41@reddit

The bridge itself weighs far more than the plane, or any collection of planes that might be sitting on it. Most bridges' (all concrete bridges') primary load is their own weight.

[-]

jared__@reddit

its not the engineering, its the construction.

[-]

orgpekoe2@reddit

…who do you think does the calculations to ensure something actually works?

[-]

lemonylol@reddit

It'd be like being worried about driving under a highway underpass full of cars.

[-]

Mole-NLD@reddit

Your dad is what we'd call: a dangerous driver...

[-]

Big_Primrose@reddit

SeaTac Airport has one also. S 188th St goes under the south end of 16L-34R. It’s fun driving under when something lands.

[-]

riptomyoldaccount@reddit

I work at a place with a commute that includes a small tunnel with a taxiway over it. I’ve driven under A380s, 747s and F22s. It’s pretty rad.

[-]

cachopo_con_patatas@reddit

How is that not a security issue?

There is no fence on that bridge visible. One can throw/catapult/trebuchet anything into this slow rolling plane or into engine inlet.

[-]

bubba_ranks@reddit

As someone who remediates taxiways and runways daily, I would never drive under that tunnel.

[-]

njreinten@reddit

Your pops probably just wants to look at that majestic aircraft lol

[-]

Please if the A380 was damaging the bridge due to its weight, im guessing it wont just suddenly fall through hut rather the bridge would slowly degrade and eventually collapse while OPs dad is driving under a 737. /s

[-]

Cagliari77@reddit

Tell me you're not an engineer without telling me you're not an engineer.

[-]

CeleritasLucis@reddit

Yeah, but people are allowed to have some absurd "nope, i am not gonna do it".

[-]

on3day@reddit

As long as they are not holding up traffic that now needs to be aware of someone randomly braking on the left lane.

[-]

racsorry@reddit

I mean assuming the video isn't mirrored, and taking into account people saying that it's Sidney, the left lane is the slowest lane ;)

[-]

Spearlance@reddit

It’s not mirrored or the letters on the plane would also be mirrored

[-]

It’s narrow. It should be fine.

[-]

Radioactive_Tuber57@reddit

Dang, that beast is HUGE in this context. Great visual reference!

[-]

darksidathemoon@reddit

Did they calculate the load limit by parking more and more A380s on it until it failed and then rebuilding it with that number as the limit?

[-]

mass_mike47@reddit

This is probably a dumb question but is it safe to allow people this close to an aircraft. What’s preventing someone from tossing a brick at the wing or engine?

[-]

luigifelipe@reddit

Wow

[-]

DruPeacock23@reddit

My gf would have stopped her car on the middle of the road due to fears that she might run into a plane.

[-]

Rivenaleem@reddit

I don't get the title here. The bridge was built before there were planes that large taxiing across, so his fear isn't entirely irrational, right?

[-]

midsprat123@reddit

If the bridge couldn’t support them

They wouldn’t be allowed to cross

Therefore the fear is 100% irrational

[-]

CantDoThatOnTelevzn@reddit

The title’s logic suggests preexisting infrastructure is automatically rated for any and all future equipment.

[-]

dbcooper4@reddit

The A380 was designed to have a a lower main landing gear wheel loading than a 747. Hence it’s backwards compatible with airport infrastructure that can support a 747.

[-]

relayrider@reddit

and that the inspectors are qualified AND not corrupt

[-]

dc456@reddit

Same - it makes no sense.

It’s not ‘but’ - it’s why he doesn’t trust the bridge. Because it was built before they had an idea a plane this big existed.

[-]

CantDoThatOnTelevzn@reddit

No, you’re right; and I’ve been scrolling the thread feeling increasingly insane.

[-]

agha0013@reddit

The A380 was designed to distribute it's weight properly without requiring all the airports of the world to repave and replace all their infrastructure.

Building new jet bridges and gate areas specific for it was one thing but there was no way they'd sell any if it required airports to replace much more expensive infrastructure.

It's main taxing restriction is on taxiway width and turn radius. Not weight

[-]

dbcooper4@reddit

I remember a video where they pointed out the A380 has more wheels so that its wheel loading is lower than a 747’s.

[-]

Lokitusaborg@reddit

That looks a lot like the taxiway over Sepulveda at LAX. I know it’s Sidney, but when you seen an A380 roll across it you do sort of take stock in your own perception of reality.

To avoid too many people on the road below slowing down to get a good look?

In that case, here's a free tip for you: don't put a target on your back by defending such a stupid reddit decision in the comments, it makes people more curious.

I taxi the 747 over these bridges and I sympathise with your Dad. Tell him from me it's just as unnerving for us.

[-]

DrEarlGreyIII@reddit

yeah i feel like i would be shitting bricks every time that i needed to taxi over this bridge, don’t mind driving under though

[-]

oh-pointy-bird@reddit

Tell us more? Which part feels unnerving? Is it more the width of the span or the concept of it?

[-]

Fluffy_Duck_Slippers@reddit

They have these bridges at a few airports around the world but it's quite rare and they don't make it obvious on the airport chart you're about to taxi over a motorway. After a long haul flight you're naturally pretty tired, focal length is a little short, you might not have been to this airport in ages then you taxi round a corner and all of a sudden there are hundreds of cars heading directly towards you. Takes a second to register what's going on. The 747 is damn heavy at max all up landing weight, 302 tonne and it's all concentrated on 18 wheels. Some airports don't come close to having the pavement strength to handle it, but this narrow bridge is fine, doesn't feel natural. True engineering marvel.

[-]

oh-pointy-bird@reddit

Very cool to read your experience of it! I can only imagine. Thanks.

[-]

swift1883@reddit

In a 380 one can barely feel the plane touching down. I think if the bridge collapsed underneath it, the people upstairs might not even wake up unless it’s 10 feet down lol. So smooth it’s boring.

[-]

Slazagna@reddit

Your title makes no fucking sense dude. Wtf has tge bridge being built before a380s got to do with it bwing safe ro drive under when an a380 is on it. If anything thats evidence towards your dad's.... sorry, your DADs argument.
