China's mega bridge touted as the "longest sea bridge in the world" connecting Hong Kong, Macau and China's southern Guangdong province of Zhuhai has several technological super features which set it apart from any other similar structure worldwide.

The over 34 km bridge which is much longer than San Francisco’s elite Golden Gate Bridge has special "yawn cams", meaning it monitors the driver if he is likely to fall asleep on the wheels while on the bridge.

The cameras on the bridge also report on the physical condition of the driver and send out alerts if a driver yawns more than three times in 20 seconds.

Interestingly, the bridge's high tech system also reportedly monitors heart rate and blood pressure of the driver.

The bridge cuts jouney between Hong Kong, Macau and mainland China by several hours which is hosted on the Pearl river delta as China pushes to integrate commerce with Hong Kong.

The bridge which reportedly cost over $20 billion will connect a string of underwater tunnels and artificial islands.

The mega bridge will open to traffic on Wednesday, a day after its inaguration today by President Xi. Authorities expect over nine thousand vehicles to cross the bridge everyday boosting people-to-people contract and trade ties between the three big commerical centres.

China's vice premier Han Zheng during the inaguration ceremony said the project was deployed and driven by Xi Jinping personally" while Hong Kong leader Carrie Lam asserted that the bridge would transform Hong Kong from a "connector to a more active participant".

The plan for the bridge was envisioned soon after Hong Kong was cecded to China by Britain in 1997, however, building began only in 2009 as China saw the economic potential of linking three great cities.

It however has some restistrive features, for example Hong Kong residents will only be granted a licence to cross into Zhuhai by car if they meet highly selective criteria, including holding certain mainland government positions or making major contributions to charities in the southern Chinese province of Guangdong, newswire AFP reported. 

Most people will need to travel on coaches and buses, according to rules layed down by the Chinese government.
