China is the midst of several megaprojects that will transform its cities.

Over the next decade, China plans to encourage 250 million people (29 times New York City's population) to move into the country's growing megacities.

To cope with that huge migration, the country has invested tens of billions of dollars in giant infrastructure projects.



Touted as an engineering wonder, the world's longest sea bridge, which connects Hong Kong, Macau and mainland China, includes a snaking road crossing and an underwater tunnel.

Called the Hong Kong-Zhuhai-Macau Bridge, the project is expected to cut travel time in half.

Commuters will be able to travel across the Pearl River Estuary from Macau to Hong Kong in about an hour.

Nine years after construction began on the 55-kilometre (34-mile) crossing, a preview organised by the Chinese government offered a first peek into the megaproject.

The bridge will link Hong Kong to the southern Chinese city of Zhuhai and the gambling enclave of Macau, cutting across the waters of the Pearl River Estuary.



Although the official opening date has not been confirmed.

Dogged by delays, budget overruns, accusations of corruption and the deaths of construction workers, the bridge failed to open by the end of 2017 as hoped.

There have also been safety concerns after 19 lab workers were charged over faking concrete test reports, with one man jailed last December.

china is the current global super power, one day will be one day, Nigeria will become

The 420,000 tonnes of steel used for the project represent 60 times the amount used in the Eiffel Tower, China's official Xinhua news agency said.

Gao Xinglin, the bridge's project planning manager, said the construction of the 6.7-kilometre underwater tunnel gave him sleepless nights.

"There were many nights where I couldn't fall asleep, because there were too many difficulties during the construction," Gao told reporters Wednesday.


"Linking the 80,000-tonne pipes under the sea with watertight technology was the most challenging," he added.

The bridge features six lanes and four tunnels, one of which is underwater.

Cars will have to change sides of the road when they get into Hong Kong, which drives on the left.

Third mainland bridge

China also built four artificial islands to support the structure.


The 2012 photo below shows artificial islands China built for the bridge near Lantau Island, in Hong Kong.

Some 40,000 vehicles are expected to use the bridge daily, including shuttle buses running at 10-minute intervals.

Pedestrians will not be able to cross the bridge, nor will bicyclists; it's just for cars.

Officials say the bridge will be up and running for 120 years.




China is already home to first and second longest sea bridges, which spans 34 miles and 26.3 miles.

The second completed in 2011, the $1.5 billion structure links the eastern coastal city of Qingdao to the suburb of Huangdao.

This bridge still dey learn for where third mainland bridge dey. The only bridge in Africa where you can rock 240km/hr and nothing will happen.

Abeg... ayam not sure the same God created all races in this world
.... Especially blacks... No value to the world whatsoever. The only value we add is to ourselves.... we just be better pest ... even me.....

None should mention me oo. I'm not feeling fine

Meanwhile it’ll take Naija decades to construct a simple mainland bridge.

Nature can be cruel. But they should have known with all the sunami and stuffs they get. There are limits, one thing Chinese refuses to admit. Well I'll wait, for that bridge I must see.

On the last day of 2017, the country celebrated the completion of the world's longest sea bridge, the Hong Kong-Zhuhai-Macau Bridge, with a spectacular fireworks display.

The fireworks were a part of the lighting-up ceremony for the mammoth motorway bridge and were witnessed by around 10,000 construction workers.

The bridge is being built by three different governments in China, so it can only open when all sides are ready.

What can I type?

The People's Republic of China, Macau and Hong Kong governments?

With all honesty china is ahead of America.

and we still find it hard to connect Bonny island to port Harcourt

Africa is cursed with bad, visionless leaders and unreasonable followers.


What a wonder up there!

God is definitely in China! May good things come out of our own Galilee too.

God of China is a leaving God oo

How!!?

China isn’t as developed as USA in many fields. Roadworks and traffic are messy in China.

The only field China is more advanced than USA is probably the railroad and subway system

Name some of the fields where China isn't as developed as USA..

Science and Technology, Economy

While somewhere ordinary second Niger bridge which is not up to 4km still dey hard them,what a cursed country.

You are wrong China economy Right now has overtaken that of US, in technology they are at per with US. Tell me Which Technology US have that is alien to china..

Hooleeshit
High way to hell

ok

This is astonishing, we are indeed far behind in technological and innovative advancement than the rest of the world.

Have personally sent some mails to top firms in China about replicating what is obtainable there here in Nigeria but the response....

Anyway we are bridging the gap in no small measure

With the construction of the Oceanna, indeed it will be an edge.
Invest now and be an owner for life in Oceanna.
