Forums > Travel Yunnan > Highway Engineering Marvels and Global Comparisons Is there anywhere else in the world (apart from China) with as many tunnels and as much total tunnel length on a single length of highway as there is in this place in China?
The G8011 Mengzi-Hekou (蒙自-河口) expressway is hundreds of kilometers from the nearest major city, Kunming, but it contains what I believe to be one of the world's most impressive collections of tunnels. Over a length of 23.3 kilometers, the G8011 descends 850 meters in elevation into the Red River Valley (红河谷), passing through 14 tunnels, three of which are over 1000 meters long, and which add up to a total of 10,244 meters of length, making 44% of this stretch of highway tunnels (if the final tunnel is excluded, 9.528 meters of tunnels over 18.9 km of highway calculates to an even high proportion of tunnel at 50%).
If you want to examine this stretch of highway for yourself on google earth, then you can check these two sets of coordinates:
A) 23°06'39.58" N 103°17'24.93" E
B) 22°58'57.66" N 103°24'39.40" E
Looking for a counterpart in the United States, I calculated that Interstate 70 passes through a total of 6 tunnels while crossing the Colorado Rockies, for a total of 4,915 meters over 252 km of highway, meaning 0.02% is in tunnels. Clearly, there's no comparison here.
Is there anywhere in the world that could match this example I've found from China (excluding other examples in China itself....which are numerous)?
What does this say about Chinese engineering and highway development?
Why are Chinese highways so much more tunnel-intensive? Is it because the landscape is more mountainous and the tunnels are necessary? Or is it because Chinese engineers are more willing to build a tunnel through a mountain than build around it (if so, this presents an interesting departure from the cultural adage that the Chinese method of dealing with a problem is to go around it rather than straight through it).

Yes, I think the shit will hit the fan. By which I mean China is facing at the very least a prolonged recession, or worst. Something akin to Japan's "lost decade" (in reality lost *three* decades). There are just too many forces for this to not happen. Demographic, structural, developmental, geopolitical. The dang knows it, that's why they're preparing people to "weather the coming storm". It's just not normal to have 30 years of nonstop growth. If China wants to have "capitalism with Chinese characteristics" then it can't avoid the periodic crises that are inherent in capitalism.
I'm in China at the moment, but based outside China long-term, and as @lemon lover surmised, I've got no real money to "transfer out".

发布者@Liumingke1234 and @Ishmael I agree it's all very unsustainable. When the shit hits the proverbial fan these places will be the first to go belly up. Symbols of China's early 21st century excess at its peak.

Not to sound like a capitalist pig here, but this is not a government project. It's a private sector project by a Hong Kong-based property developer. Property developers are in the business of developing property, not funding poverty relief, education, health, etc.
While I don't disagree with you that Kunming has a glut of of unnecessary luxury shopping malls, the urban planner in me has to defend this project purely based on its location. This project is located right on top of Kunming's first and so-far only subway transfer station, at the confluence of the main North-South and East-West trunk line subways. A location like this makes total sense for a big, magnet multi-use project like this. People will be able to come here by subway, reducing the amount of car traffic downtown. This is much better planning than the more suburban shopping malls like those around Dianchi which are more auto-oriented than transit-oriented.
The historical evolution of Yunnan's Zhongdian, aka Shangri-la
发布者Great article as always.
One little geographical typo, though, in the 8th paragraph.
The county referred to as "Diqing" (迪庆县) should in fact be "Deqin" (德钦县) 。 Diqing (迪庆州, or 迪庆藏族自治州 in full) is the name of the Tibetan Autonomous Prefecture to which Zhongdian (中甸) aka Shangri-La/Xianggelila (香格里拉县),Deqin (德钦县), and Weixi (维西县) Counties belong.
