[@atholmullen]

My idea for crossing the Strait of Gibraltar would be to build an underwater bridge with enclosed deck, probably at the depth between the two currents to minimise loading, designed to allow for the movement of the tectonic plates. The simplest way to allow for movement would be a longitudinal curve that is designed to be able to change radius slightly while maintaining structural integrity and seal. Tunnels would be bored or blasted from the land at each end to the ends of that undersea bridge. The effective result would be a relatively shallow tunnel.

[@matsv201]

under water bridges (or float tunnel that they also are known as) will probobly be revolutionary when the production start hitting a peak. Not only should the be the cheapest way of building connections (because they can be pretty much fully be built in dry dock), but they are also easy to transport and mount. But so far non have been built But there is a issue with a under water bridge. Trains. Trains have a maximum weight of 15ton/meter and a typical weight (medium weight freight trains) 5ton/meter. That is a lot of change in weight. And any train that will come will probobly be longer than the distance between the floats or peers. While under water bridges have the benefit of being partly floated, hence they can span huge distances with very little support, this is a big problem for trains.

[@darylcheshire1618]

​​ Complicated construction and cheap don't go together. It would be more feasible if it was solely used for unmanned cargo transportation, pumping air in to keep enough oxygen would be a massive waste of power. Leave it to an engineer to over-engineer.

[@scottzema3103]

A couple of thoughts: Oil platforms regularly are used well in excess of the depth of the straits; perhaps such structures could be adapted as bridge supports. Also, maybe a strong cable system anchored to the sea floor could support floating towers for an otherwise normal cable extension bridge; these floating towers could be further connected to one another structurally under the waters of the strait to form in essence one giant partially submerged beam or structural chord acting to reinforce the overall bridge from below and prevent moment developing in pivot points identified with the tower supports against storm and tide lateral forces. This substructure would be connected like the bridge to both shores and would as such as prevent general moment in the entire bridge itself. Also note of course should be taken of the role of strong truss supports in the bridge under either side of the roadbed which not only prevent movement of the roadbed like Galloping Girtie but act to reinforce the structure as well.

Any bridge structures would need to be extremely strong to withstand the effects of both wind and snow/ice build up.

It is said the Mediterranean was once a salt basin, with the odd dotted lakes where river flowed in.

(People are going to think I'm ADHD and they may be right!) Anyway, on the oil platforms I want to clarify that to the extent such structures extend both above water and are anchored below, oil rigs may offer a path to developing secure footing in extreme support depths in another application. (Also, on the other idea, perhaps the floating tower bridge and connected support structures could be hinged on the sides and open in the middle like the Dutch dike dams to break and pivot in the central sections to one side of the strait or the other in extreme circumstances; ie here instead of trying to always withstand storm surge of sea water flow and storm activity through the straits ('bridge closed temporarily due to inclement weather') and then swung back into place. No need to subject the structure to more wear than necessary.) But again aside from the natural seabed secured platform concept, what I am alternatively suggesting and thought of perhaps another way is some kind of secured artificial floating platform which is independent of the seabed as a base concept (except perhaps for cable securements*) and which supports a raised road and rail bed. Here, in my particular idea, this takes the form of a suspended roadbed on floating tower structures; the whole secured by massive perhaps steel box supports between the towers to keep the whole system stable and all of one piece and adequately submerged to allow sufficient passage. To all appearances and purposes an ordinary suspension bridge above the water, but underneath the bridge is part of a floating or suspended structural system. A type of structural platform if you like, independent of the sea floor. And think of the advantages of engineering a bridge to stand independent of such a geologically unstable area like the straits! With this basic idea of an artificial seabed perhaps progress can be made (or has already been somewhere) on bridging more difficult areas around the world. * On the cables, these could be arranged underneath the structure extending upwards like an upside down extension bridge cable array from the sea floor to the underside of the nonmoveable parts of the bridge, perhaps on both sides like a stabilizer and on both shores to additionally keep the structure stable in the water. IE situated towards the banks of the straits and not intruding into shipping channels; again also submerged at depth. I admit I'm using the information from the excellent video in developing these ideas and have not followed the engineering on Gibraltar to this point. Certainly the engineering solutions to bridging problems are many and really fascinating. Questions of cost? Always a question. OBTW the bridge structure could be engineered to take advantage of the tides with the installation of turbines, perhaps in the lower structural chord element tying the bridge towers together between. Talk about your cheap electricity in Morocco. OH and sales of electric power to offset costs besides the tolls!! Just ideas. Thanks again.

[@andymanaus1077]

What about floating tunnels? Long sections can be built in dry docks with sealed ends. They are then floated out to the appropriate location, attached to the previous section. Cables are then attached to the sections and massive concrete anchors buried into the ocean floor. The sections are submerged by incrementally shortening the cables. Finally, the sealed ends are removed, leaving a continuous tunnel floating at a predetermined depth. For safety, two tunnels could be built parallel with escape tubes from one to the other. Due to being made from slightly flexible materials, floating tunnels are naturally resistant to ocean currents, earthquakes and shifts in the seafloor. They do not need to be near the ocean floor, nor anywhere near shipping traffic. The cables would require maintenance but the tunnels and anchors could be built with redundant connection points so new cables could be fitted and tensioned before the old ones were replaced.

[@NoobGamingXXX]

[@u1zha]

I bet that they will build like that someday. Hard to hold something like that at predetermined depth when heavy trains travel through - that's something you forgot to mention. The slightly flexible materials and their maintenance cost a lot in the face of current construction techniques and risk tolerances.

[@andymanaus1077]

@@u1zha You're right. In the environment of the Straits, anything they make will be subject to extreme forces approaching or exceeding the strength and resilience of current building technologies. I honestly don't think there will be a practical crossing of any kind for at least another 50 years. Even then, any construction will require daily maintenance and constant monitoring just to prevent catastrophic collapse.

[@Hamsun56]

A major flaw in the analysis here is that a rail tunnel to Morocco only connects to Morocco, it doesn't functionally connect to the rest of Africa as there is no continental rail network or road network in Africa. Aside from the geography, and infrastructure issues, you have political divisions between countries that don't allow for free movement. Those issues need to be solved before even contemplating a tunnel from Spain to Morocco.

The best option would be an enormous zip line.

[@polreamonn]

@9 km or 14 miles - That's the other way round Simon.

[@windingroadelven]

I actually liked the island idea

[@NoobGamingXXX]

Have no sense economically

[@rafaelrondon1813]

Why not suspend a tunnel above the seabed? It seems like it would solve the problems raised, albeit by doing something never before attempted.

[@jessesmith-garcia5313]

hahaha...Simon and his BEARD....Hilarious!

[@holymelon8011]

It'd be awsome to drive from Terra Del frago to cape town, maybe I should do that saddly ain't no ferry between Alaska and russia

[@alfrredd]

I heard the Ice actually freezes sometimes and you are able to drive/walk between Alaska and Russia.

Although the mega Dam across the Gib Straights is absurd, image all the archeology dropping the Med by 200m would reveal - not least the wreck of the Britanic at 110m!

[@williamlloyd3769]

Given density of human habitation in Sahara area of Africa, there appears to be no economic reason to build a bridge to support trade. Expect ship borne trade will be more effective

[@muleskinnerfilms6719]

Your acting is getting better, lol

[@calebburrell9920]

We need to see a pic of him with hair!

[@wildcountry.]

Its always struck me as crazy that African raw materials are freighted to African East Coast then shipped to China made into goods then shipped to Europe. Way more sustainable to cocreate manufacturing in North Africa and freight direct to Europe. I suspect part of the problem is USA doesn't want that level of cooperation between Europe Africa and Asia?

[@hooks4638]

If you haven't done a mega projects on the Ryfast System then you should.

[@Whiskey2shots]

Honestly I think just building a rail tunnel similar to the channel tunnel on the shallower portion is the smartest way to go. You could have a car transporter train if necessary but going to 24 lanes I frankly absurd.

[@NoobGamingXXX]

the shallow portion is still 2.5 times deeper than the channel and also this video didn't talk about the nature of the sea bed which complicate things even more

[@Whiskey2shots]

@@NoobGamingXXX indeed, I mean the whole project is almost impossible. But a tunnel is likely to be significantly easier than a bridge and the 20 lane monstrosity mentioned would frankly be absurd

[@CHMichael]

Imagine 2 modern 5+ million residents city's across from each other ( Barcelona and Dubai example) There would be a bridge and a tunnel already built 30y ago. Think of Euro tunnel. There just isn't enough money on the African side. .....and just think of the tide energy plant.

[@mattsyson3980]

Since the UKk is still (after 3 years) having difficulties sending sausages from England to Northern Ireland I think it might be fair to say British bridge/tunnel solution won't be happening.

[@kukuc96]

I like the dam idea just because of the sheer insanity of it. Except for the lowering of the sea level by so much. But, it could control the rising sea level problem thats a problem in places like Venice, and return the sea level to the 1900 level or something like that.

[@GrandTourHTX]

How many channels does this guy have???

[@JeeVeeHaych]

As impressive as this sounds, my first thought was 'no way this is gonna happen, 'cause migration....'. Unless Spain would actually be so bold as to think they could just link Ceuta/Melilla to the mainland and leave it at that.

[@rafaelrondon1813]

What’s wrong with migration?

[@HandsOfSweed]

​@@rafaelrondon1813 You serious, Clark?

[@JeeVeeHaych]

@@rafaelrondon1813 Not talking wrong or right but it's a contentious enough topic, especially if it involves linking the African and European continent.

[@MikeZ8709]

​@@rafaelrondon1813 it's about what's wrong with a direct, cheap, fast link. It would be one-way migration from shitland to Europe, thus screwing over a lot of Europeans.

[@pads-zr9ln]

​@Rafael Rondon yeah nothing wrong with millions of barely literate people turning wanting free housing, health care and other entitlements

[@MartijnPennings]

Meanwhile we've not been able to build a bridge for the 100.000 people per day commuting between the center of Amsterdam and Amsterdam North, which is a ferry ride of about 200 meters...

[@Tjalve70]

This is looking at only ONE problem. It is better if they look at TWO different problems. The sea is rising. And that will flood coastal cities all over the world. But the Mediterranean is in a unique position where they can do something about this. Because if they DAM the Gibraltar Strait, they can limit the amount of water that enters The Med. And thus they can make sure that the sea level in the Med remains constant, even if the sea level in the rest of the world rises. And it shouldn't be a problem to make every country on the Med to pitch in to pay for this. And once there is a dam there, of course it should be easy to build a road. I would suggest making a dam of rock rather than concrete. Since the tectonic plates moving might break a concrete dam, but would only shift a rock dam.

[@ssreeser95]

40 Views? Last time I was this early, Simon had hair!

[@zackerymeltonturdle5648]

We need evidence of Simon with hair

[@MaD0MaT]

Wouldn't it be easier to build such bridge from Sicily to Tunisia? Sure more than twice longer, but in shallow waters and with less traffic.

[@NoobGamingXXX]

It's also about the what can sicily and tunisia bring to the table .. Tunisia is not a bridge to Africa like Morocco and Sicily is semi isolated with a fucked up economy. Compare that to Tangiers one of the largest docks in the region and Spain main land it's a no brainer

[@barrydysert2974]

A wee bit skeptical are We Simon !:-)

[@davidlobaugh4490]

I'd bet they keep using boats. With that fault line and the distance from either end for ventilation and emergency....makes a lot more sense to keep using ships.

[@Chris-op7yt]

floating bridge made of sections with archways so shipping can pass underneath

[@antonnym214]

At 1:00, you say that 9km is 14miles. You mostly got that backward. 14 km is 8.7miles. BUT the straight of Gibralter, acording to NASA, is 13km or 8 miles. Hope this helps.

[@debralittle1341]

Wow is that even safe

[@milind006]

Came here to mention the “9km or 14 miles” error, but there are already 2 comment threads on it. Damn!

[@Epsilonsama]

Whistler promoting anti hair loss products is the most youtube thing ever.

[@alexpeli2449]

What about an underwater bridge? The suports wouldn't be too high and the tunnel too deep. Build it in sections and sink it like the Denmark tunnel.

[@u1zha]

The seabed where Denmark tunnel lies is < 40 meters down. Big difference if your seabed lies 400 - 900 meters down. Probably much steeper gradients too.
