History Of Aizhai Bridge

Construction on Aizhai Bridge commenced in October 2007. It was part of a national expressway from the Chongqing to Changsha. The expressway’s total length was 64 km (including 52 bridges and 11 tunnels), in addition to upgrades on about 129 km of existing local roads. The entire construction project cost roughly $610 million.

Situated deep in the heart of beautiful Hunan province near Jishou, Aizhai Bridge is the largest structure on the expressway from Jishou to Chadong. Engineers constructed two tunnels on either side of the bridge, ingeniously using one of the mountaintops for the location of one of the towers. This method reduced the overall cost of the bridge’s construction, and likewise, it blends more naturally into the environment. As a safety precaution, a substantial number of rock anchors were constructed at the surface of the rock, to ensure the stability of the bedrock. In addition, an extensive study was undertaken to ensue the safest method of construction.

Spanning across Dehang Canyon, Aizhai Bridge was one of the key structures of the entire expressway project. It was situated at the halfway point of the expressway, near the village of Aizhai, hence its name. Construction on Aizhai Bridge was completed at the end of 2011, ahead of schedule. Almost immediately, it became a major tourist attraction for the region. Visitors can enjoy a walkway partly made of glass, which is accessible via a large group of elevators and escalators. Aizhai Bridge is world-renowned for the spectacular views enjoyed by those who cross it.

Culture Of Aizhai Bridge

Aizhai Bridge gets its namesake from the tranquil, neighbouring village of Aizhai. The Miao people, who primarily live in the mountains of southern China, inhabit this wonderful village. The Miao live in Hunan, Guizhou, Sichuan, and Yunnan, among other provinces.

Because of the remote mountainous location of Aizhai, the Miao inhabitants have maintained a more traditional lifestyle. Residents live in wooden houses built on stilts in the ganlan-style, called “diaojiaolou”. Essentially, ganlan-style refers to any structure that is supported by wooden stilts or columns. The diaojiaolou in Aizhai are all two or three storeys high. Visitors to the village get a glimpse of the fascinating and unique culture and traditions of the Miao people.

Adjacent to Aizhai Bridge is a meandering section of the China National Highway 319 (G319). This 6 km stretch of road snakes along the mountain and has 13 tight bends, with astounding 70 to 90 degree angles. The highest section of the road is 440 meters, and is about 7 meters wide. Construction on this section of the highway was completed in 1935.
