Bright Side

Engineers are working on a bridge idea so huge it sounds impossible: linking Africa and Asia with one insane mega-connection. This video breaks down where it could actually be built, why the location matters, and what kind of engineering headaches come with strong currents, deep water, and nonstop shipping traffic. Some plans involve bridges, tunnels, or even hybrid systems, and the cost numbers get absolutely mind-blowing fast. It’s not just about travel—it could reshape trade routes, economies, and how people move between continents forever. Mega projects like this prove humans don’t just build roads… they rewrite maps 🌍🌉  Animation is created by Bright Side.  ----------------------------------------------------------------------------------------  Music from TheSoul Sound: https://thesoul-sound.com/   Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV  Subscribe to Bright Side: https://goo.gl/rQTJZz  ----------------------------------------------------------------------------------------  Our Social Media:  Facebook: https://www.facebook.com/brightplanet/  Instagram: https://www.instagram.com/brightside.official  TikTok: https://www.tiktok.com/@brightside.official?lang=en   Stock materials (photos, footages and other):  https://www.depositphotos.com  https://www.shutterstock.com  https://www.eastnews.ru  ----------------------------------------------------------------------------------------  For more videos and articles visit: http://www.brightside.me  ----------------------------------------------------------------------------------------  This video is made for entertainment purposes.

00:00For eons, the Red Sea has separated the continents of Asia and Africa.

00:05They're close enough to wave at each other, but far enough that moving between them requires planning.

00:11Ferries do the job, but it's time for something better.

00:14That's why engineers have envisioned an ambitious mega-project of tunnels and bridges

00:18that will not only link the two continents, but also reshape the region forever.

00:23Millions of years ago, the Arabian landmass slowly drifted away from Africa,

00:31opening a watery scar that we now call the Red Sea.

00:35This place is famous for its crystal-clear water that looks filtered even when it isn't,

00:40as well as for coral reefs that seem to be painted by an overachieving artist.

00:45Let's zoom in on one specific location, the Strait of Tirun.

00:49Every ship headed toward the upper ports squeezed through this one busy hallway.

00:55On the one side is Egypt, the Sinai Peninsula, rugged, golden, and sprinkled with resort towns.

01:02On the other side, it's Saudi Arabia, the Tabuk coast,

01:06where quiet desert hills stroll right down to neon blue water.

01:10The distance between them looks tiny on a map, almost like someone forgot to connect the lines.

01:15That's because the Strait is only about 8 miles from peninsula to peninsula,

01:21close enough that on a clear day, you can sometimes see the opposite shoreline.

01:26It's a busy gateway, and it's the exact gap designers want to turn into a direct road and rail link.

01:33So what are they actually trying to build?

01:35The idea is to create one continuous route between the Sinai Peninsula and the Tabuk coast.

01:41Engineers are still deciding whether it should be a bridge, a tunnel, or a hybrid, the combination of two.

01:47The problem is under the water.

01:49Near the shore, the bottom is shallow enough to support strong columns,

01:53but as you move farther out, the seabed drops quickly until it reaches about 900 feet.

01:59It's almost like walking off an underwater cliff.

02:03That sudden plunge is too deep for standard bridge supports.

02:07The design has to adjust to the landscape instead of forcing one shape across the whole gap.

02:12If they go with a bridge, the builders would place huge steel tubes called caissons on the seafloor.

02:18Think of them as giant metal buckets.

02:21Once they're in position, the water gets pumped out so crews can build a dry foundation inside.

02:25Concrete turns that space into a pillar rising from the seabed.

02:30The floating cranes drop long road sections between those pillars like puzzle pieces.

02:35It works well in shallow areas, but anchoring becomes difficult in deep waters due to high pressure, soft ground, and strong waves.

02:45Tunnels avoid this by going under the problem, literally.

02:48Crews can send tunnel boring machines called worms,

02:51or they can build submarine-sized tunnel segments on land and sink them into place.

02:56It's the same trick used in the Hong Kong Zohai-Macao Megalink,

03:00which proves it works even in busy deep water.

03:04Now, people might look at the map and think,

03:068 miles? That doesn't sound so bad.

03:09In reality, it's nothing like tossing a giant tree trunk over a river and calling it a bridge.

03:14Cars, buses, and trains need those long, slow, friendly ramps that don't feel like a roller coaster.

03:21By the time you build those ramps on both sides, the whole thing could stretch to nearly 20 miles.

03:27That puts it in the same club as giants like the Chesapeake Bay Bridge Tunnel in the U.S.

03:32or the King Fahd Causeway between Saudi Arabia and Bahrain.

03:36But it's not just the scale or unpredictable seabed that makes this intercontinental project challenging.

03:42There's also the climate.

03:44Temperatures regularly pass 100 degrees Fahrenheit.

03:48Concrete dries faster than planned, so crews have to cool it or work in shorter windows.

03:54Steel stretches in the heat just enough to make precise work annoying.

03:58And workers themselves cannot stand in direct sunlight for long without feeling like a baked potato.

04:03On top of that, the salty sea air chews through metal quicker than most people expect,

04:09so the whole structure needs tough protective layers and regular checkup.

04:13If this project gets the green light, you're looking at a timeline of several years.

04:17A good comparison is the Orison link between Denmark and Sweden.

04:23It's only about 10 miles long and still took around 4 years to build,

04:27in an environment that is much easier to handle than the Red Sea.

04:31Then, there's the price tag.

04:34Early numbers land around $4 billion, but that feels more like a starting guess than a final bill.

04:40If they run into problems, that figure will almost certainly climb.

04:45There's also one other problem that must be brought up.

04:48Swimming right under the surface.

04:50The Strait of Tyran is home to dolphins, rays, sea turtles, and even sharks.

04:56Including harmless reef sharks that glide around like they're protecting the beautiful, colorful corals below.

05:02These reefs aren't just decoration.

05:04They're some of the healthiest in the entire Red Sea.

05:07Scientists say that in parts of the northern Red Sea,

05:11some corals tolerate higher temperatures than many others around the world,

05:15which makes these reefs especially valuable from a climate resilience perspective.

05:20That means even a single mistake during construction could cloud the water with sediment,

05:26and that alone can smother corals like dust settling on wet paint.

05:30The same goes for noise, drilling, and ship movement.

05:34Reefs can't exactly move away if annoyed like fish can.

05:37Once they're damaged, it can take decades for them to grow back.

05:41That is, if they grow back.

05:43To avoid that, planners have to build in ways that keep the water as clear and calm as possible.

05:50Construction zones may need silt curtains to stop sediment from drifting away.

05:54Heavy equipment might have to avoid areas with dense coral clusters.

05:58Some sections could lean more toward tunnels instead of pillars to leave the seabed undisturbed.

06:05Every decision has to match the underwater map, not just the one on land.

06:09On top of that, the whole project would need constant supervision from scientists and inspectors.

06:16They would have to check how cloudy the water becomes and how marine animals behave during the work.

06:22If something looks off, the only responsible move is to slow down or change the method,

06:28instead of just rushing to finish faster and leaving the reef to pay the price.

06:31But if everything finally clicks into place, the payoff is massive.

06:38Right now, if you decide to skip the ferry and stay on land, the map punishes you.

06:43You have to loop all the way around the top of the Red Sea,

06:46through other countries, on a drive more than a thousand miles.

06:50All of that just across a stretch of water that is only a few miles wide at its narrowest point.

06:55It's like walking around the entire block just to knock on your neighbor's door.

07:00A permanent link would change this.

07:02Travel time drops, ports on both sides become easier to reach,

07:06and a drive from Africa to Asia suddenly feels as normal as crossing a long highway bridge.

07:12Not to mention the coolest part, which would be the view if they decided on the hybrid version.

07:17You begin your journey on the Sinai side, with the desert behind you and the Red Sea ahead.

07:22Instead of waiting in a ferry line, you roll onto a rising ramp while the water glimmers below.

07:29The road dips into a tunnel under a busy shipping lane,

07:33and before long, you're back in the sunlight on the other side, now on a different continent.

07:38The train version could feel even smoother.

07:41You find your seat, the doors close, and the train glides toward the crossing without any stop-and-go traffic.

07:47It slips into its own tunnel section, runs quietly under the sea,

07:52and pops back up on the Asian side before you have even finished scrolling your feed.

07:57For tourists, that could mean more resorts, more quick weekend trips,

08:01and a brand-new continental hop that becomes a must-try experience.

08:06For delivery trucks, every hour saved is money earned.

08:09Even local towns would feel the change.

08:12They'd get more visitors, more trade, and bigger profits.

08:15A link like this doesn't just connect land.

08:18It connects economies, ports, and everyday life.

08:21And that's a giant opportunity, as long as the underwater world stays protected.

08:28In Asia, there's a bridge that is way longer than you'd think should even be possible.

08:32The HZMB stretches 34 miles over open water, which makes it the longest seabridge in the world.

08:40So if something this massive can make it across rough waters,

08:44why can't New Zealand just build a bridge between its two main islands?

08:48After all, we're talking about a distance of just 14 miles.

08:53And a bridge like that could seriously change life for both locals and tourists.

08:58People could just hop in a car and drive from Wellington to Picton.

09:01No more ferry hassles, no more drawn-out trips.

09:04Just one epic road journey with ocean views on both sides.

09:09So what's stopping them?

09:11Well, turns out, everything.

09:13I mean, building a bridge there is technically possible,

09:16but there are a couple reasons why experts are like,

09:19hmm, maybe not.

09:21Let's start with the obvious, the distance.

09:24The North Island and the South Island are separated by Cook Strait.

09:27Like I said, it's 14 miles wide at its narrowest point.

09:32That's not much, true.

09:34Plus, we've got the HZMB bridge, proving that, yep,

09:38it is technically possible to build a bridge over the sea to cover that distance.

09:42But we can't ignore the fact that New Zealand's geography is,

09:46well, a whole different ballgame.

09:49Cook Strait isn't exactly a calm, friendly stretch of water.

09:52It's deep, really deep.

09:55Parts of it drop to about 10,000 feet.

09:58That's like stacking seven Empire State buildings on top of each other.

10:02It's also a rough, moody stretch of ocean that loves tossing around ships like rubber ducks.

10:08In fact, quite a few have been wrecked in Cook Strait.

10:12And sadly, many lives were lost.

10:15You don't have to worry about it so much, though,

10:17as the worst accidents happened a long time ago.

10:20The ships and ferries that cross it today are much safer.

10:24Even so, it'd be pretty hard to avoid getting seasick while crossing it.

10:29Things get even messier below the surface.

10:32The seafloor over there is uneven and unpredictable.

10:36What happens is that Cook Strait has opposing tides at each end,

10:40one where it meets the Tasman Sea and the other where it joins the Pacific Ocean.

10:45And they simply don't move together like you might expect.

10:48When the tide is high on one side, it's low on the other.

10:53And they're totally out of sync.

10:55So all that water rushes back and forth through the Strait to balance things out,

10:59creating some really strong and messy currents in the middle.

11:03Then there's the weather.

11:05Cook Strait isn't just windy.

11:07It's probably one of the windiest places in the Southern Hemisphere.

11:10That's because it's located right in the middle of one of New Zealand's three big wind tunnels.

11:17Basically, there are places where the wind doesn't just come and go quickly.

11:21It sticks around, blowing hard for most of the year.

11:25And all of this happens because of something called the Roaring Forties.

11:28That's the name for the latitude band between 40 and 50 degrees south of the equator,

11:35where strong, persistent, westerly winds are pretty common.

11:39Unlike the Northern Hemisphere, which has a lot of land at this latitude,

11:43the Southern Hemisphere is mostly ocean with just a few land masses,

11:48like New Zealand's South Island, Tasmania, and the southern tip of South America.

11:53So, these winds go wild because there's nothing to slow them down,

11:59and they just keep picking up speed.

12:01The gusts there can reach up to 150 miles per hour.

12:06So, imagine trying to cross a bridge in a car when the wind is actively pushing against you.

12:11That's not just unpleasant.

12:13It's super dangerous.

12:15Drivers can easily lose control of their cars with the wind pushing them sideways.

12:19And, of course, that can lead to countless serious accidents.

12:24Now, let's talk about earthquakes.

12:27New Zealand sits right on the boundary of two massive tectonic plates,

12:31the Indo-Australian and Pacific plates.

12:34It's basically in the middle of a collision zone.

12:37And about 14,000 earthquakes happen in and around the country every year.

12:43Of those, only about 200 are big enough to be felt.

12:47Still, building a massive bridge under these conditions would require some serious, genius-level engineering.

12:55With all that in mind, we can safely say that the whole bridge idea is off the table.

13:00But how about an underwater tunnel?

13:05Yep, that could work.

13:08It could be a great solution, actually.

13:10No wind, no bad weather, and no earthquakes to deal with.

13:14There are a bunch of other advantages, too.

13:16First, it would dramatically reduce travel time,

13:21cutting down the three- to four-hour sailing trip between the North and South Islands.

13:25That same journey would probably only take about 40 minutes.

13:30Then, people wouldn't have to stress about all the ferry cancellations and delays because of bad weather.

13:36And most importantly, it's doable.

13:38I mean, look at the Channel Tunnel.

13:40It's an undersea tunnel connecting southern England and northern France.

13:45Japan did something similar with the Seikan Tunnel, which connects the islands of Honshu and Hokkaido.

13:50They are both huge projects, serving pretty much the same purpose.

13:56So why on earth isn't New Zealand already building this tunnel?

14:01Well, for the same reason we don't all live in luxury treehouses with personal robots.

14:06Money.

14:06Estimates vary, but some experts think a project like this could cost anywhere from 10 to 20 billion dollars.

14:15To cover that kind of cost, they'd probably need to charge tolls for the next hundred years.

14:20And trust me, those tolls wouldn't be cheap.

14:23Other experts think it could actually cost more than that.

14:27Because, you see, we have to consider all the extra infrastructure.

14:31The narrowest point of Cook Strait is between the North Island and Arapoa Island.

14:36That's one of the long, mountainous regions in the Marlborough Sounds, which is pretty remote.

14:41So it's not just about the cost of the bridge or tunnel itself.

14:45It's also the access roads, safety systems, maintenance, and evacuation plans.

14:50You can't just build a huge underwater tunnel and not plan for the occasional emergencies.

14:56And what would it actually be used for?

14:59Sure, there are people who travel between the islands.

15:01About a million passengers take the ferry every year.

15:05But that's not exactly the kind of traffic that justifies the most expensive infrastructure project in the country's history.

15:12Earlier, we talked about how England and Japan have similar underwater tunnels.

15:17But there's something to consider.

15:18The United Kingdom has a population of 69 million.

15:23Japan has even more, with around 123 million people.

15:28And in New Zealand, they've only got 5 million residents to pay for this project.

15:33So could they have a tunnel under Cook Strait?

15:36Sure they could.

15:37Should they?

15:38Oh, probably not.

15:41If you don't want to fly, the only other way to travel between the islands is by ferry.

15:45It's not ideal, but hey, it works.

15:49New Zealand has a total of 5 ships that transport people and vehicles across the islands.

15:54For tourists who aren't in a rush, it's perfect.

15:58You can cross the islands while taking in some of the most stunning views and spotting amazing wildlife.

16:03You'll start your trip in Wellington, and right from there, you'll see the rugged North Island coastline as you head out into open water.

16:11You might see different seabirds like gulls and terns, and as you get closer to the South Island, you might spot some gannets.

16:18If you're lucky, you could also catch a glimpse of the seal colonies off the coast.

16:24During the last hour of the trip, the ferry will slow down, giving you plenty of time to enjoy the green hills and calm waters.

16:32You will also approach Queen Charlotte Sound, a spot known for its wildlife.

16:38So keep an eye out for orcas, playful dolphins, and even penguins.

16:41Honestly, having a ferry instead of a tunnel might not be so bad after all.

16:50That's it for today.
