Video: World’s longest sea bridge now fully connected



The main section of what will be the world’s longest sea bridge has now been connected.

A ceremony was held in Zhuhai to celebrate completion of the Hong Kong-Zhuhai-Macao Bridge, as the focus will now shift to road surfacing and other related tasks.

The Guardian described the incredible feat of engineering “one of the seven wonders of the world” and will overtake the bridge that crosses Jiaozhou Bay in eastern Shandong Province as the world’s longest sea bridge.

The bridge will be 55Km long and will connect Hong Kong, Macao and Zhuhai – the three largest cities in the Pearl River Delta region. It will include a 6.7 km underwater tunnel and a 23-km bridge over the sea.

The three hours time it takes to travel from Hong Kong to Zhuhai will be reduced to just 30 minutes.

Construction on the bridge had to take into account any potential impact on the nearby airports of Hong Kong and Macao and on one of the world’s busiest shipping routes. It was imperative that the project did not disrupt any of these operations.

Construction began in 2009 and the structure is expected to have a lifespan of 120 years.

More than 400,000 tons of steel has been used in the construction process.

The structure has been designed to withstand severe weather such as super typhoons. It will also be able to cope with earthquakes up to eight on the Richter scale or even a collision with a 30 tonne vessel.

The project is expected to complete in late 2017.
