Jiaozhou Bay Bridge China

World's longest sea bridge spans 42.5-km over Jiaozhou Bay

The world's longest bridge on the sea, the new Marvel of modern Chinese design, was opened to traffic on Thursday.

42.5 km arc extends across the spectrum of the blue waters Jiaozhou Bay and connects the northern port city to flourish with the Qingdao airport built on a nearby island, and the industrial suburb of Huangdao. The first car to roll the Y-shaped bridge sixlane, 33.5 m wide road was cut in half the time their journey to the other side of the bay, just 30 minutes.

Built-in four years the cost declared by the Chinese state media, $ 2.2 Billion, the bridge is located on the pillars and the 5200 is designed entirely by Chinese engineers in Shandong Gausu Group.

At least 10,000 workers toiled two teams around the clock to build the bridge, working from opposite sides of the bay and connects the two ends together in the middle.

While working on the deck, more engineers while building a tunnel under the bay follow, which will help facilitate the flow of traffic.

A total of 450 000 tons of steel were used in construction - enough to almost 65 Eiffel Towers - and 2.3 million cubic meters of concrete.

Chinese officials said the bridge would be strong enough to withstand a magnitude 8 earthquake, hurricane, or the impact of 300000 tons of the ship.

The bridge has replaced the previous world record for duration of the Lake Pontchartrain Causeway in Louisiana, no less than four miles. However, it is eclipsed in 2016 by another Chinese bridge trestle, connecting Hong Kong, Macao and Guangdong Province and is about 50 km in length.
