10 Facts about world’s longest sea bridge – Hong Kong – Zhuhai – Macao Bridge
The world’s longest sea crossing bridge opened to the public on October 23rd, 2018 by Chinese President Xi Jinping.
Almost 700 guests, including the leaders of Hong Kong and Macau, attended the event for the opening of the $20 billion bridge. The HZMB will be the longest bridge-cum-tunnel sea-crossing with dual 3-lane carriageway, which is about 35.6km in length from the shore of northern Lantau to the western shore of Pearl River Estuary.
1. The Hong Kong – Zhuhai – Macao Bridge (HZMB) construction environment is complicated. It is designed to withstand frequent typhoons, crisscross navigation, airport height restrictions, high environmental standards, etc have been taken into considerations.
2. We could say it as kind of private bridge as everyone will not be allowed to drive through the longest sea bridge. Only those who are wealthy or are politically connected will be permitted to drive their private vehicles through the bridge, the news agency reported. The administration will issue 10,000 licenses for Hong Kong-mainland dual-plate private cars, while the quota for licenses for Macau vehicles is just 300. People who do not have a license would have to use public transport to reach the bridge and then change to cross on private buses, AFP reported.
3. Drivers always need to stay alert when they are driving on the bridge. Special cameras installed on the bridge will keep a tab on the bus drivers and would alert authorities if they yawn too many times, AFP quoted Hong Kong media as reporting.
4. Blood pressure of the drivers will also be monitored. As the bridge is Chinese territory, where people drive on the right side of the road, drivers on the Hong Kong-Macau bridge would also need to switch the side of the road when they are on the bridge.
5. A whopping amount of 420,000 tonnes of steel was utilised in the construction of the massive bridge. According to the AFP report, the amount of steel used in the construction of the bridge was enough to build 60 Eiffel Towers.
6. About 30km of its total length crosses the sea of the Pearl River delta. To allow ships through, a 6.7km section in the middle dips into an undersea tunnel that runs between two artificial islands.
7. The bridge, which will open for public from Wednesday, is expected to reduce the travel time between Hong Kong and Zhuhai from three hours to 30 minutes. The bridge will also aid in boosting trade activities between mainland China and Hong Kong
8. There have also been concerns about the environmental impact, with conservations groups saying the project may have caused serious harm to marine life in the area – including the critically rare Chinese white dolphin.
9. Chinese officials say it will generate up to 10 trillion yuan ($1.44tn; £1tn) for the economy, but doubts have been cast on that figure by Hong Kong lawmakers.
10. It has been dubbed the “bridge of death” by some local media outlets. At least nine workers on the Hong Kong side have died and officials told that nine had died on the mainland side, too.
