China holds the record for the worlds longest sea bridge at a cost of 6 trillion naira and seven years of construction time. The bridge spans a record-breaking 55 kilometres, that’s 5 times longer than the third mainland bridge which connects Lagos island to the mainland.
The Chinese record-breaking bridge connects mainland China with its autonomous provinces of Hongkong and Macao. It would cut travel time from a whopping 3hrs between Zhuhai in mainland China and Hongkong to a mere 30minutes. The bridge is meant to boost economic activities between mainland China and its autonomous provinces and also affirms chinas grip on the autonomous provinces.

Nigeria can learn a lot from the planning and execution of this bridge. The quality of a nation's infrastructure reveals the economic situation of that nation and China is a perfect example of the correlation between Economic growth and world-class infrastructure. Unfortunately, Nigeria exudes very poor basic infrastructure and in some cases a total lack of such infrastructures.

Lack of funding and corruption eats away any chance of having a marvel like the Chinese sea bridge. Cases like the second Niger bridge, where a lack of political will and unavailability of funds have hampered the construction of the bridge.The completion of the Second Niger bridge would have lead to a boost in the volume of Economic activities in Nigeria, especially in the Southeastern axis.
There are plans for a fourth mainland bridge that would be funded through a PPP agreement between the Lagos state govt and a consortium of private firms. The bridge is proposed to span 38km and costs a whopping 844bn naira. When completed it would set a record as the longest bridge in Nigeria and overtake the 6Th October Bridge (20.5km) in Egypt as the longest bridge in Africa.
Aside from breaking records and being an architectural Marvel, the 4th mainland bridge would make a statement to the world that Nigeria is finally ready to take its place as the economic powerhouse of Africa.

Magnificent

This is scaring, 55km long distance like Lagos toll gate(Motorway) to Kobape close to Abeokuta estimated cost @$15.1 billion.

This no longer news its already commissioned for use.

Updated the post to reflect the fact that it has been completed, been following the bridge for up to 5 years now, due to increasing cost, construction and political issues the project kept on being delayed. Even at that, 7 years and 6 trillion for a 55km bridge that's meant to withstand earthquakes and some of the harshest environmental factors is a marvel to be celebrated.
I intended to highlight the several lessons Nigeria can learn from this. We abandoned the Ajaokuta steel industry( Which I am finishing up an article on), abandoned the River Niger dredging and lots of so many projects that could have placed us on the map.
Thanks for the update

China to unveil world's longest sea bridge
1 APR 2018
Source: TRTWorld and agencies Officials say the bridge connecting Hong Kong, Macao and mainland China, touted as the world's longest , will boost business and cut travel time, but critics see it as an attempt by Beijing to tighten its grip on the Special Administrative Regions.
The total price tag for the project, which includes artificial islands, link roads and new border-crossing facilities, is unclear but some estimates run to over $15.1 billion. (March 28, 2018) (AFP)
Billed as the world's longest sea bridge connecting Hong Kong, Macau and mainland China, it has been touted by supporters as an engineering wonder.
But critics say the multi-billion dollar infrastructure mega-project is politically driven and a costly white elephant – especially as it was dogged by delays, budget overruns, accusations of corruption and the deaths of construction workers.
Building started in 2009 on the 55-kilometre crossing, which includes a snaking road bridge and underwater tunnel, linking Hong Kong's Lantau Island to the southern mainland Chinese city of Zhuhai and the gambling enclave of Macao, across the waters of the Pearl River Estuary.
Officials say it will boost business and cut travel time, but opponents in Hong Kong see it as another attempt by Beijing to tighten its grip on the semi-autonomous city.

NOP, that one was completed earlier around 2011 at a distance of 41km in China. It "WAS" the longest before this marvel of 55km was built.
China is a country of serious minded people.

It seems if you want anything to get done, you call the Chinese. The land reclamation they have done is outstanding.
I am about finishing up my article on the Eko Atlantic city and lessons for the others states in Nigeria.
