What's your opinion about these projects? Do you think the money is being spent wisely?👇

Thanks a lot for watching & supporting us 💛

The line city is the most delusional and extravagant project ever proposed and constructed. It is inconceivable how such idea might be viable in real life.

[leoni]

Biggest scientific experiment: 25b
City that no one really wants: 1.5trillion

Imagine how much humanity could achieve if they invested that 1.5t into something meaningful

[pudanielson]

California high speed rail is honestly worth it because driving 2 hours into work and 2 hours back is soul crushing, and it only gets worse as more people move there.

[justinmanser]

18:20 300, 000 residents in Neom. That sounds like a very selective group of people living hundreds of miles away from anywhere. I'd like to know the position and nationalities of those who will live there. Seems almost like a Bond villain hideout to me.

[seangriffin]

Any list that includes NEOM should also include a Mars City and artificial superintelligence - All vaporware that will not be built in the next decade.

[glennelliott]

You should do a report on projects with the biggest overrun by $ and percentage. As example, Vancouver Sewage plant budget at $900 mil, now $4 billion and construction stopped as everyone suing each other

[ipg]

So you're telling us that Xiongan, an entire city of more than 5M people which also includes and HSR to Beijing cost less than LA-SFO HSR?!?!

[CIutchX]

The California Railway is the prime example of a much needed project that has been poorly planned.

[djwhat]

Yeah I MAY start believing Neom will actually be for real when Sindalah is finished and people are traveling there.

[Hakuna_Frittata]

$32, 000 an inch to build a 6 mile subway to serve 54, 000. Absolutely ridiculous.

[KyrilPG]

Very interesting!
The Grand Paris Express is building 200km of new lines and extensions, which gives roughly 400 km of new tracks as the lines are dual tracks. More than 100km of tunnels had already been dug as of early 2024, , so a bit over 55% of the tunnels have been built already.
All the extensions pertaining to the Grand Paris Express project have already opened to the public in June.
So, line 14 is fully open from Saint-Denis Pleyel Northern transit hub to Orly airport in the South, since late June.
There are 23 new stations and roughly 34 kilometers of new rail based transit that has opened this year alone in Paris :
13 new stations and about 22km of metro extension on lines 11 and 14.
3 giant new stations and 8km on RER extension on the West side if line E (the regional express heavy metro).
7 new stations and 3.5km of extension on the circular tram line T3b.
Towards the end of next year, they'll open the first section of M15, the huge 75km long fully underground loop metro line circling Paris.
M15 South section will have 16 stations and will be 35km long. The two remaining sections of M15 should open between 2029 and 2031.

The BART 10km extension is outrageously expensive... That's about 1.22 billion dollars per kilometer of extension. About 5 to 6 times more expensive than a deep bored kilometer under Paris' very high urban density and pretty terrible soil conditions.
It's also about 7.4 times the cost of Barcelona L9-L10 which is a deep single bore design built under a very densely built and populated urban fabric. Barcelona L9-L10 costs about 165 million per kilometer of deep single bore... (that's including the 52 stations in the average cost per kilometer for a 47.8km line that's 91% in deep tunnels).

As for HS2, now that the Labour is in, maybe they'll restart the project and get either French or Spanish advisers to build their high-speed line efficiently and for a reasonable cost...

Great unbiased summary - what a wonderfully, magnificent, diverse world we live in!

[philipmurphy]

Always worth watching a good MegaBuilds video

[paulb]

So Canada is spending billions on a plant that is exporting its resources, should be to keep Canadian energy prices low and sell what they don’t use like renewable energy

[carsofdubai]

I’m Australian living in Abu Dhabi. Could you please cover some of the projects on saadiyat island 🙏 some of the projects are so big I don’t even know what to think of them anymore. Or even Etihad rail

[petelosuaniu]

Sydney Metro - It’s great. I travel on it but it often closes down on the weekends for ongoing track testing and building down the line in the parts still under construction. However, it’ll open to the CBD and to Sydenham (half the total kms in routes) on 4th August 2024.

[doopedoog]

could you maybe post videos from some unpopular countries as well? would be nice to see their projects and how they are progressing for the better as well, rather than already popular mega projects from already known countries.

a tip i would give is maybe a video about The Country of Georgias new mega project which is an 300km-400km+ highway project which includes multipal tunners and bridges.

thank you and absolutely love your videos!!

[zanmar]

Love this video, very exciting mega projects coming up

[formercityboy]

these projects all sound extremely inspiring and ambitious. will be the biggest fun to come back in 5 years and check who achieved what. :)
