One of China’s best-known roads, the Ya’an-Xichang Expressway (Yaxi highway), part of the Beijing-Kunming Expressway, connects the city of Ya’an to the city of Xichang in the southwestern province of Sichuan. It is nicknamed the “highway in the clouds” because it rises 7.5 meters per kilometer (24.6 feet per 0.6 mile) and because of its imposing infrastructure.

Some information about the Expressway in the clouds
Yaxi Highway description:
This 240 kilometer (150 miles) long expressway is part of the G5 Jingkun (Beijing to Kunming) Highway in Sichuan Province. It starts at the edge of Sichuan and runs to the Hengduan Mountains, crossing the Qingyi, Dadu, and Anning rivers, as well as other river systems and 12 seismic fault zones, and stretching through high mountains, overlying mountains, and hazardous terrain.
The area along the route rises from 600 meters to 3,200 meters (1,970 feet to 10,500 feet) above sea level.
This road is essentially a combination of some super viaducts and some super long tunnels, and there is no flat terrain. There are 25 tunnels with a length of about 41 kilometers (25.5 miles), including 2 extra-long tunnels and 16 long tunnels.
Ganhaizi Bridge is one of the most impressive and difficult to build on the Yaxi Expressway. It is located in Shimian County, Ya’an, Sichuan, at an altitude of 2500 meters (8200 feet). It has a total length of 1811 meters (5940 feet) and a bridge width of 24,5 meters (82 feet) with a total of 36 spans. The highest steel tube truss structure reaches 117 meters (383 feet). In fact, it is the first reinforced concrete truss bridge in the world.

The road is open all year round. Although, always check the weather before driving there as it is a zone known for its speed-changing weather conditions.
This road is definitely not a highway like any other. Indeed, its construction began in 2007 and was inaugurated in April 2012, that is to say, less than 6 years of work at a cost of 20.6 billion yuan (3.3 billion dollars). If you are a fan of road infrastructure, you must absolutely take an interest in the Yaxi Highway.
