The Aizhai Bridge (矮寨大桥) is a suspension bridge on the G65 Baotou–Maoming Expressway near Jishou, Hunan, China. The bridge was built as part of an expressway from southwest China’s Chongqing Municipality to Changsha. It connects two traffic tunnels in the mountains, cutting the time needed to traverse the canyon from 30 minutes to 1.

Construction on the Aizhai Bridge began in October 2007 and was completed by the end of 2011, ahead of schedule.The bridge was temporarily opened to pedestrians during the 2012 Spring Festival[8] and was formally opened to traffic in March 2012.

The bridge was built with the assistance of a $208 million loan from the Asian Development Bank; the loan also funded 64 kilometres (40 mi) of expressway construction and upgrades to 129 kilometres (80 mi) of local roads. The bridge and the associated road construction were projected to reduce the travel time between Jishou and Chadong from 4 hours to less than 1 hour.

In September 2012, the Aizhai Bridge was the site of an international BASE jumping festival that included more than 40 jumpers from 13 countries.

Aizhai Bridge is 336 m (1,102 ft.) high and has a 1,176 m (3,858 ft.) span, making it the world’s longest and highest suspension bridge.

China Builds ‘World’s Tallest Building’ in Changsha, Hunan Province

China Building World's TallestSky City 

China builds ‘world’s tallest building 

Sky City” in Changsha, Hunan Province, China will be world’s tallest skyscraper building by April 2014.

Heights Comparison It will be 220 floors above ground with a total height of 838 meters; will have a planned construction time of only 10 months; and cost 1.5 billion US$.

This will stand tallest at 838 meters/2749 ft. till the “Kingdom Tower” of Saudi Arabia is finally constructed. Its proposed height is 5,280 ft. which will be more than twice the height of Changsha’s structure at 2,749 ft.

Screen shot 2013-07-28 at 10.55.53 PM Screen shot 2013-07-28 at 10.57.00 PMThere will be 104 high-speed elevators; 10 fires escape routes, which can evacuate people each floor within 15 minutes; the building will be fire-resistant for up to three hours.

It will also have 17 helipads.

Sport facilities will include 6 basketball courts, 10 tennis courts.

Plans include preserving green space around the building.

Sky City at Night

This “city” building will house shops, restaurants, offices, 5 schools, an elderly care centre, and a hospital on the lower levels; while 31,400 people apartments and 1,000 guests’ hotels would make up the upper levels.

The 4-layered glass windows will keep the temperature of the building constant between 20 to 27°C.

The air indoors will be filtered to 20 times cleaner than the outside air.

The lamps used in the building will be energy saving LED.

The building is designed against earthquakes of up to 9.0 on the Richter Scale.

China’s Aizhai Suspension Bridge, Hunan

Aizhai Bridge connects two traffic tunnels in the mountains, cutting the time needed to traverse the canyon from 30 minutes to 1. The bridge was built as part of the G65 Baotou–Maoming Expressway, an expressway in southwest China‘s Chongqing Municipality to Changsha, near to Jishou, Hunan.

With a main span of 1,146 metres (3,760 ft) and a deck height of 350 metres (1,150 ft), it is the sixth-highest bridge in the world and the world’s twelfth-longest suspension bridge. Of the world’s 400 or so highest bridges, none has a main span as long as Aizhai. It is also the world’s highest and longest tunnel-to-tunnel bridge. The bridge contains 1888 lights to increase visibility at night. (Wikipedia)

Construction took five years. Work finished at the end of last year, making it among the world’s longest and highest suspension bridge, carrying traffic 355 metres above the foot of Dehang Canyon. Construction of the bridge started in October 2007 and its main sections were completed at the end of last year. It is designed to help ease traffic in the mountainous region, where queues are common due to the narrow, steep and winding roads.

Aizhai is the fourth suspension bridge in China to cross a valley so wide that it seems to be connecting two mountain ranges. The first three were the Siduhe, Balinghe and Beipanjiang 2009 bridges. Located deep in the heart of China’s Hunan Province near the city of Jishou, the suspension bridge is the largest structure on the Jishou to Chadong expressway with a deck 1,102 feet (336 mtrs) above the DeHang Canyon.

The two tunnels on either side of the Aizhai Bridge allowed the engineers to use the mountain top for the location of one of the towers, reducing its height to just 165 feet (50 m) – unusually short for a bridge with a span nearly as long as the Golden Gate bridge at 3,858 feet (1176 m). In addition to cost savings, the stubby support also allows the bridge to blend more naturally into its surroundings. The taller bridge tower is no less unique with side span cables that soar down the backside of a mountain, making first time visitors quizzical as to what exactly lies ahead.

With most of the structure hidden from view, the bridge will come as a jaw-dropping surprise whether you enter the canyon from either tunnel. Due to a gap of approximately 328 feet (100 m) between the last truss suspenders and the tops of the bridge towers, the engineers added some additional ground anchored suspenders to stabilize the two massive suspension cables and reduce any oscillations that could damage other components of the bridge. An overlook and visitors center will offer additional views of the broad valley.

Tianmen Shan – Hunan, China

Tianmen Shan – Heaven’s Gate

James Cameron‘s recent epic movie “Avatar” (Floating Mountains) no doubt helps to promote the spectacular wonders of the Chinese mountain scenic attractions.

All too well, people have long been familiar with the ancient mountains located around the vast Chinese landscape so mysteriously depicted in Chinese paintings.

The five famous mountains – Huangshan, Taishan, Huashan, Hengshan & Songshan are now facing competitions with newer discoveries such as Tianmen Shan or Tianmen Mountain.(Chinese Mandarin word“Shan” means “Mountain”).

Tianmen Mountain in Hunan Province just south of Zhangjiajie City (previously known as Dayong City) is an absolutely ‘must see’ scenic area.

The main featured scenic spots are centralized in the north part of Zhangjiajie City – Wulingyuan Scenic Area which became China‘s first National Forest Park in 1983.

Cable Cars

The best way to get to the top is by cable car. A one-way trip costs CNY48. The roads are scary with many twists & turns & certainly not for the faint-hearted.








Big Gate Road

If you have more time to stay in Zhangjiajie , there are lots of places you may want to visit . . . to fill your thrills & frills . . . too many to mention here because of time & space constraint.

A scenic spot you might enjoy is the Feng Huang Cheng (Phoenix Town) located some 210 kilometers (about 130 miles) west of Zhangjiajie Village. Here you can experience that Chinese minorities lead a life of primitive simplicity unaffected by the ways of modern development. This raises the question that in the failing realm of capitalism, shouldn’t economists consider the aspect of GDH instead of GDP – H as in HAPPINESS rather than P in PRODUCTIVITY. Could you be content & happy living just a basic lifestyle?

Finally, the newly opened Yangjiajie Scenic Area located in the northwest section of Wulingyuan is worth a visit.

Like they say “A picture is worth a thousand words”, you’ll be amazed by the slide show as presented by pps creator Dan Calistrat or view on YouTube the airflights through the Heaven’s Gate.

Flying Through Heaven’s Gate


This is  China’s newest tourist spot with a glass-bottomed walkway around the cliff face of the Tianmenshan – a feature similar to the Skyway of the Grand Canyon in US. However, this is of greater  distance 200 ft long & stands at 4,700 ft. above sea-level.

To walk on it is to test your nerves, to see whether your heart can stand the dazzling height!
