The world's longest sea bridge will also be ‘green’, featuring electric vehicle charging stations

Written by  TheStructuralEngineer.info

The first major combined bridge and tunnel sea-crossing project in China is the Hong Kong-Zhuhai-Macau Bridge project. Consisting of three cable-stayed bridges and one 6-km sea crossing tunnel, it will have a total length of 55 km. It will be the world’s longest sea bridge and will link three cities in China's Pearl River Delta — creating one mega-city of 42 million people and slashing travel time between Hong Kong and Chinese city Zhuhai from three hours to just 30 minutes.

The ‘green’ element

550 electric vehicle charging stations are expected to be built on an artificial island off the bridge, with an investment of 90 million yuan ($13 million).  The 429 DC and 121 AC charging stations will be used to charge different kinds of electric vehicles, such as public buses, long-distance coaches, taxis and private cars. "They will help facilitate green development," representatives of the Guangdong branch of China Southern Power Grid said.

The sad aspect is that since 2009 when construction work began, 10 workers have died and more than 600 have been injured in 275 incidents. The Y-shaped bridge, which is due to open in December 2017, has so far cost HK$117 billion, after repeated budget overruns.
