Chinese President has authoritatively opened the 55km world's longest sea crossing bridge.
The 6th longest extension on earth took nine years to finish.
Built at the cost about $20bn (that is over ₦7trillion) and designed to last 120 years, the mega structure is strong enough to withstand earthquakes and typhoons. Waoh! See more photos...
Part of the total crossing consists of a 30km bridge that crosses the sea. A 6.7km underwater tunnel also runs between two artificial islands to allow large cargo ship containers to pass through.
China also boasts of the World’s Highest Bridge ,the ₦52billion 1.34 km bridge between Xuanwei city and Shuicheng county, that is as tall as a 200-storey-building.
