If not a subway, then put a EL instead. It is cheaper and scenery too.

The subsurface beneath Manhattan can only support so much. This is especially true when you consider the drilling and excavation for foundations, utilities, and subways. I've been concerned for some time that these coastal cities are going to begin experiencing catastrophic structural failures in their buildings without any help from weather or earthquakes. Just pure soil failure.

why does saudi arabia comes up with the most bizarre, unattainable, unsustainable and short-sighted projects?

think of the great wall thousand years ago....

NYC is a wreck.

Great great great....China is china again

It's possible. But neither sensible nor required.

Even new civil engineering students know that you must always build a foundation over a stable layer (bedrock, for example), using deep piles if necessary. This whole thing about “soil improvement” is just a hilarious, unproven-with-skyscrapers technology gimmick to justify their expensive simulations, jobs, and ridiculous contracts, at the cost of investors, residents and the city itself.

No one need it. Too few money in Africa. Since crazy German plans about railway Berlin to Capetown (yes, orly!) no one sees anough profit from this link.

No thanks if materials they're using are made in some communist country

Gratifyingly greater percentage of grown up engineering based comments so far and even better, there are very few shout them down angry rants jumping on to the backs of those who do mention the mass movement of people. At present I'd say that such a bridge is still within the realms of a solution looking for a problem. Of course, it could be a case of Build it and they will come. But for now and having read every comment, I tend to agree that the flow of commerce tends to be at 90° to any bridge. Neither Europe nor Africa imports and exports vast quantities of goods on the polar axis, most traffic is East - West. Unless and until the continent of the future that is Africa begins to realise its huge potential, the present state of solution looking for a problem will annoyingly remain.

Nothing wrong with wishful thinking architecture if you're building a grass hut.

Already built ours here in Foster City, CA.

In short time them blades will harmed by the sun.

IT was a piece of Liberal party corruption to put money in the pockets of selected liberal supporters . No one in the West wants the airport there where the planes will end up polluting the major Sydney water supply Warragamba dam and the intermediate reseviour at prospect . There is no rail freight line scheduled for the airport nor a direct passenger rail link Because of the insufficient public transport in the western growth region so it will take around 2 hours by road to get to & from it during daylight hours . It will take around 300 B double tankers to supply fuel which will further congest the roads that will not be big enough to handle the projected volumes . The land around it was not "undeveloped wasteland" but actively farmed producing much of the fresh food, particularly leafy greens consumed in Sydney. The 'Modern waste water management " is another disaster as the overflow which can be massive will discharge into the Nepean river up stream of the Wallacia weir so cause extensive flooding of the upper & lower Nepean river plus drastically add to the floods on the Hawkesbury particularly the city of Penrith which will flood much much more frequently because all of the water that previously would have soaked into the working farm land eventually flowing into the Hawksbury river via South Creek which is substantially down stream of major flood choke points will now race off the massive sealed catchment and overflow into the rivers . The airport is not wanted nor needed . The problem with Australian aviation is the capital city Canberra does not have an international airport big enough to take large modern jets so all of the international business & government delegates that need to come to Canberra to engage with the government have to arrive via Sydney or Melbourne then get a connecting domestic flight to Canberra. Sydneys problem is a city of 4 million has only 1 alternative domestic airport to Mascot and that is at Bankstown which is also at capacity . Wha t was needed was the Sydney -Goulburn- Canberra-Albury-Melbourne fast train link that has been on the drawing boards for 50 years but gets vetoed in order to protect the property prices in Sydney & Melbourne . From the 80's on the City of Goulburn was begging to have the airport built there but the various governments found every slease bag reason why it would not be allowed to be built, even if 100% privately funded . IT would surprise you in particular , because your research is garbage the the heaviest trafficked air route in the world in Melbourne - Canberra , not NY to LA and the Sydney - Canberra route comes in at number 12 . Add to that getting to it will be a disaster and distributing freight from it will be a bigger disaster as Badgerys Creek to Palm Beach will be a full days work for a truck driver . As of now only some 10th rate Chinese airlines are the only ones seeking landing slots at Badgerys Creek and it will be a massive white elephant . Since Avalon in Victoria has been upgraded to international status as has Newcastle . And of course to prove just how corrupt the whole procedure was from start to finish . The day the final selection was announced all of the land under the proposed flight paths got sold off as it could not be used for growing vegetables but there were no development restrictions so because this was cheap "airport affected" land shifty developers ( all of who line government pockets ) bought this land and built over 70,000 residential houses under the flight paths which have of course been changed to the point of making the night flights do a 270 degree turn from 300 feet elevation making the flight path almost as dangerous as Sans Paulo

MBS must be very pleased this year. The river is amazing. The desalination is very advanced. I hope to travel there someday. I hope I will be received kindly. My skin is light. Lingering glances.

The Japanese should send some experts to Venice, to study how the sinking problem is solved there.

The TBMs are most assuredly not guided by GPS directly, given that they are operating underground. Where GPS is known to .. not work at all for obvious reasons.

Qadhafi already executed a similar idea. It got sabotaged.

I can’t take it We have planes ,they are faster and go in a straight line any destination in California is only an hour away at most,plus it’s 70 BILLION over budget But hey COMMUNISTS China has one and we want to be just like them

I cannot imagine anything worse than having to live in NY. Or anywhere in MuriKKKa for that matter. The European Invaders have made one of the most beautiful Continents in the World into a nightmarish abomination of concrete, glass and steel. A soulless, suffocating jungle of pollution, poisons and putrefaction. No class, no values, no purpose except the hoarding of wealth by the few and the impoverishment of the underclass. Just looking at that ghastly skyline of Monuments to Mammon makes my Soul scream and my mind shudder. I am SO thankful I'll never have to see it in Person!

You achieve this only when you are not the tail of the west… the Turkish people where only herders but because of their faith they built the most sophisticated “empire of faith” … when kamal ataturk came in power he preferred the west he abolish the Quran, he ban the hijab… etc so he start tailing the west… it took Turkeye no where… Erdogan wanted to build his own house not begging the west to let in their barn …

Maybe, just maybe finally go with Berlin Sperenberg. Such a nonsense to add even more to Frankfurt, as it ran into its expansion limits a long time ago.

Only had to capture water running into ocean. Holding area.

This should be built 50 years ago, bet we were busy bringing “Democracy” to Iraq, Libya, Syria, Yugoslavia, Afghanistan etc.

Has anyone asked the Dutch? They are masters of reclaimed land.

It makes more sense to build above sea level, not below it. America has more than enough land to relocate.

good idea

America needs to upgrade most of our airports including infrastructure.

What about diverting exess spring ice melt water that causes Rhine and other river flooding every year, via a convergence of many small pipes from the North side of the aĺps into larger pipes that follow the roads through the mountain passes to join together into one large pipe that can by gravity alone take fresh clean water all the way down Italy, then submerged further south to rise to land and irrigate north africa?

That building was built where the supermarket pathmark once sat .landfill.

But you have missed the point!! HS2 is only and wholly about capacity. It uses higher speed technology simply because that is current technology world wide and which is in use in over 40 nations with which the UK needs to compete. In the UK we have a disastrous relic in rail engineering such that much line maintenance currently requires London stations to be closed. We have an urgent need to expand all UK port facilities and this is now nearly complete with (for example) stations like Southampton and much E-W freight being expanded to accommodate greater freight capacity. If that is to operate sensibly and be expandable in the future there is a need to further separate freight and passenger traffic. THAT is the purpose behind HS2". That is the reason a start was made in the South. That is why Manchester and the North of the UK were considered less essential at the outset. To abandon HS2 is to risk beggaring the UK economy - especially in the North. Those who advocate abandonment are really voting to put a limit on the UK economy, to perpetuate the North South divide and worse, by the absence of any alternative for the North, to making Scottish businesses increasingly unviable. Really good thinking that.

LAX airport in Los Angeles is also being renovated and expanded. They're adding two new concourses and one new terminal among many other importants. It's a 30BN program that's been happening for years.

Oh my goodness! How can you boast anything MADE IN CHINA😊

Klia 1 upgrade interiors

2:33 Thats one HUGE foundation. The size of a small country….

0:06 Takeaway the o and you get...? 😁😁😁

👏👏

Europe is the best continent on earth

Looks better than the Western Sydney Airport in Australia. 👍

A pretty impressive expansion project, are there any others we should cover?

😊

The best way to hide this is to change its name.

One minor pronunciation correction regarding soil behavior in an earthquake: The word is liqueFACtion, not liquiFICAtion. Note the spelling "lique" instead of "liqui."

What about the wifi?

You deserve to be praised, thank goodness.
