- Ya'an-Xichang Expressway Driving Tour - China's First Expressway with Double Helix Tunnels - 4K
Ya'an-Xichang Expressway, as China's first expressway with double helix tunnels, not only demonstrates China's outstanding achievements in expressway construction under complex terrain, but also provides driving enthusiasts with unique driving pleasure.
1. Overview of Ya'an-Xichang Expressway:
Ya'an-Xichang Expressway is an important transportation trunk line connecting Ya'an City and Xichang City in Sichuan Province, with a total length of about 240 kilometers. This expressway crosses the climbing zone from the Sichuan Basin to the Hengduan Mountain Area, hovering between the mountains, and passes through large and small mountains through viaducts and tunnels, crossing multiple water systems such as the Dadu River and the Anning River and 12 earthquake fault zones. There are 270 bridges and 25 tunnels along the entire line, with a bridge-tunnel ratio of up to 55%. It is recognized by domestic and foreign experts as one of the mountain expressways with the worst natural environment, the most difficult engineering, and the highest technological content in the world.
2. The miracle of the double helix tunnel:
The most eye-catching thing about the Ya'an-Xichang Expressway is its unique double helix tunnel design. In the section from Tuowu Mountain to Shimian, in order to overcome the problems of large height difference and poor geological conditions, engineers cleverly designed two double helix tunnels, Ganhaizi Tunnel and Tiezhaizi No. 1 Tunnel. These two tunnels effectively reduced the road slope of the highway by spiraling 360 degrees in situ, solving the problem of large drop. The design of the double helix tunnel not only demonstrated the wisdom and courage of the engineers, but also became a miracle in the history of world highways.
3. Driving experience:
Driving on the Ya'an-Xichang Expressway, you will pass through the misty mountains, as if you were in a flowing landscape painting. As the altitude gradually increases, the scenery along the way will also change dramatically, from the primitive forest at the entrance of the Daxiangling Tunnel, to the Dadu River Canyon in Hanyuan, to the plateau scenery in Mianning and Xichang, each one is unforgettable.
Driving in a double helix tunnel is an unprecedented experience. As the vehicle slowly rises, you will find yourself in a huge spiral, with the surrounding mountains and trees constantly rotating in your sight. This unique driving experience will undoubtedly make your trip to the Ya'an-Xichang Expressway more memorable.
4. Safety Tips:
Although the driving experience of the Ya'an-Xichang Expressway is extremely unique, safety always comes first. During driving, please pay attention to road conditions and weather changes, keep a moderate speed, and avoid driving while tired. Especially when driving on complex sections such as the double helix tunnel, you must be more vigilant to ensure driving safety.
5. Summary:
The Ya'an-Xichang Expressway driving trip is not only a journey of exploration of natural scenery, but also a journey of witnessing human wisdom and courage. On this cloud highway, you will experience unprecedented driving pleasure and a shocking visual experience. If you are a driving enthusiast, then the Ya'an-Xichang Expressway is definitely worth your visit.

记得之前冬季一下雪，雅西高速就封路。转走国道在昭觉县山上堵了一整晚都不带动的，我是南方人车上一般没有备防滑链还是当地的村民在山上来卖防滑链装好才下山。😅😅😅
The road conditions are very good.

Wow... Which route?❤
一直想看這條高速公路的路程景，謝謝小編！
請問世界除了中國還有哪個國家有這樣的雙螺旋高速公路
Rất đẹp và rất hành tráng đúng là giao thông TRUNG QUỐC...
Thank you!
Bună.Draga cameraman ce se intampla nu este descriere tradusă nu știm unde ne aflam.Te urmăresc zilnic.Te rog pune traducere.
Hello, located in Sichuan Province, China
片長時間大概50分左右，有近20公里的連續長下坡。
那個高度落差肯定很大。
有一段疑似是舊車道經修正曲率線型後的舊跡（？）
是的
这条路沿途风景不错
谢谢！

no se sabe en què paisaje posar la vista ... la carretera, la muralla de àrboles a la par, o las montañas con un agradable verde planta ... o el rìo, o los puentes o los tùneles ... todo es agradable, hermano ... despuès de nuestro paseo por el Tibet, extrañaba a mi novia, China ... I love China
Thanks bro, the Tibet video is not over yet, I wish you all the best in the new week.
Why is the toll 100 rmb per km on this expressway?
How did you come up with the idea of charging 100 yuan per kilometer? This expressway is 240 kilometers long and runs through the mountains. 90% of the length is bridges and tunnels. The cost is very high and the toll is higher than other expressways in China. The toll is 0.75 yuan per kilometer, and the toll for the entire 240 kilometers is 182 yuan.
@@jzeng2022about 20 USD..Cheap,try that in the US..cost over A 100... And CHINA doesn't have potholes,trash,broken down autos.
AMAZING....
it costs 100 million RMB per km to build.
好几个隧道里面可以简单装饰一下，现在新修的高速几乎都有贴墙砖。这种修建比较早的高速内部还是光的看起来有点突兀。
Give it a break Please.....
你是闲的蛋疼，隧道还装饰
這麼快呀？已經離開西藏了，下一步會是去那裡呢？
还没呢！317国道出藏。
