Hong Kong-Zhuhai-Macau: China opens world's longest sea bridge
It took China about €15 billion and nine years to build the world's longest sea bridge, which connects two semi-autonomous cities of Hong Kong and Macau. But this architectural masterpiece is not without controversies.
Above and under water
On October 23, 2018, Chinese President Xi Jinping inaugurated the 55-kilometer (34-mile)-long sea bridge that connects Hong Kong and Macau to the sprawling Pearl River delta economic zone via the Chinese mainland city of Zhuhai. The remarkable structure consists of a meandering bridge and a 6.7-kilometer underwater tunnel between two artificial islands.
Previous record holder
Previously, the 42-kilometer-long Jiaozhou Bay Bridge, or the Qingdao Bay Bridge, was the longest sea bridge. It is located in Shandong Peninsula and connects the cities of Qingdao and Huangdao.
Parking islands
The Hong Kong-Macau sea bridge cost the Chinese government 120 billion yuan, equivalent to about €15 billion ($17.2 billion), and its construction took almost a decade. From this artificially created island in Hong Kong, the structure plunges under water. In addition, car and truck drivers can stop here. At least 60,000 cars and 250,000 people are estimated to use this connection daily.
Expected economic boom
The Chinese government hopes that connecting Hong Kong and Macau to the Pearl River delta area would boost economic activity in the region. Until now residents of Zhuhai, Macau and Hong Kong have used ferries to commute between the three cities.
Time is money
At a speed of 100 kilometers per hour, the journey time between Hong Kong and Macau should be reduced from three hours by ferry to less than 30 minutes by car. But this is not a bridge anyone can just drive on — for now only the rich or politically well connected residents of Hong Kong and Macau will be able to take their private cars across the bridge.
Several delays
The bridge should have been officially inaugurated by the end of 2016, but it took longer than expected to open it. The bridge will be open to regular traffic from October 24, 2018. The structure will last up to at least 120 years and can also withstand typhoon winds of up to 340 kilometers per hour.
A steel and concrete giant
About 400,000 tons of steel was used in the construction of this gigantic bridge. That is 4.5 times more steel than what was used in building the Golden Gate Bridge in San Francisco. Chinese authorities say the bridge can not only withstand a magnitude-8 earthquake but also survive collisions with cargo ships.
Two driving systems
Border controls have been built on crossings in mainland China, Hong Kong and Macau. One of the problems that drivers face along the bridge deals with right- and left-hand driving systems. The drivers must also have two valid licenses to cross the bridge.
A controversial 'white elephant'
The construction of the bridge was delayed due to rising costs, fatal accidents of laborers and corruption allegations. Hong Kong residents fear Beijing will attempt to undermine their partial autonomy through this bridge. Environmentalists warn it would have a devastating impact on endangered pink dolphin species in the Pearl River estuary. Critics also say that the bridge is a waste of money.
