World’s Highest And Longest Tunnel to Tunnel Suspension Bridge

The world’s highest and longest tunnel-to-tunnel suspension bridge was opened to traffic recently in China.  The bridge, named the Aizhai Extra Large Suspension Bridge, will link together two tunnels 1,176 meters ( 3,858 ft. ) apart, and 355 meters ( 1,102 ft. ) above Hunan's Dehang Canyon. It connects two traffic tunnels in the mountains, cutting the time needed to traverse the canyon beyond it from 30 minutes to 1 hour.

Construction of the bridge had started in October 2007, and has taken nearly five years, with most of the work finished at the end of  2011. The bridge is designed to help ease traffic in the area mainly caused by its numerous narrow, steep roads. Pedestrians can walk along it on a special walkway and take in views of the Dehang Canyon.

On the bridge cars and lorries can motor along a two-way, four-lane motorway at about 50mph. Pedestrians can also walk along it on a special walkway under the road.

The bridge is a key part of the Jishou-Chadong Expressway, a 64-kilometre road which has 18 different tunnels which cover about half of its length. It is hoped the bridge will help ease traffic jams which are common in the mountainous area which has narrow, steep and winding roads. The structure is supported by a base 78ft wide and the bridge is also dotted with 1,888 lights to increase visibility at night.

China also holds the record of the longest bridge in the world, the Danyang Kunshan Grand Bridge which is just over 100miles long and was built two years ago to carry the Beijing–Shanghai high-speed railway. Here are some more photo of this massive suspension bridge, Take a look...

Chinese Man Builds Himself Bionic Hands

Sun Jifa, 51, lost both his hands when a bomb he was creating for blast fishing in Guanmashan, Jilin province, northern China, exploded. Then he finally created a new pair of arms after eight years of planning.

Sun Jifa could not afford the hospital's prosthetic limbs after the explosive for blast fishing detonated prematurely, but desperately needed the use of his hands to work on the family farm. So, he decided to create his own bionic hands.

'I made this from scrap metal for virtually nothing. There is no need to pay hospitals a fortune,' he said.

Sun Jifa spent eight years making prototypes before finally creating a pair of metal hands which can grip and hold thanks to a series of wires and pulleys inside the shell. But the only drawback is that steel is quite heavy so they're tiring to wear and get hot or cold in the extremes of summer and winter. Now he plans to develop the design for other similarly disabled people. Now, take a look at some more photo of this innovative invention...
