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).

Cycling the Nujiang: Bingzhongluo and the Tibet border
Posted byDan,
Thanks for your report.
Sean and I biked from Bingzhongluo towards the Tibetan border on January 1st, 2010. We thought we might have reached the Tibetan border after riding for a few hours from Bingzhongluo, but now that I see the sign in your photograph I realize we never actually made it. Where we turned around was a small wooden dilapidated house with a tiny store in it. Do you remember how many more km from that wooden house to the actual border it was?
Interesting that when we visited in the middle of the winter the weather was considerably better than it seems to have been for you in the summer. Blue skies, and beautiful blue water in river.
Also...did you really take a bus direct to Bingzhongluo from Kunming? Was that a standard passenger bus, or a private chartered bus? We saw no signs of passenger buses direct from Bingzhongluo to Kunming when we were there. In fact, we didn't even see direct buses from Gongshan. The furthest up the valley one could get direct from Kunming in December 2009/January 2010 was Fugong.
New Kunming airport's first phase nearing completion
Posted byIf there are to be direct flights linking Kunming to The Americas, Europe, and Australia, which cities in particular do you think are most likely to score one?
Please submit your guesses.
Mine:
Europe - London, Paris
Australias - Sydney, Melbourne
Americans - Vancouver, Los Angeles, San Francisco
Is this too optimistic? I'm not sure really how much market there is for these routes. I'd benefit, but how many others are there like me? How many actual Europeans, Australians, and North Americans live in Kunmign? A few thousand?
Then of course there's foreign tourists. That might be where it makese sense. I'd guess a good chunk of the foreigners who come to China would like to include Kunming on their itineraries? Currently the fly into the hubs in Shanghai, Guangzhou, or Beijng, and then travel to Kunming by train or domestic flight. I wonder how many would be diverted onto the new direct flights.
And then the're the outgoing Chinese market, which I imagine would not be insignificant. The number of Chinese going abroad for business, travel, and study abroad is getting bigger every year.
But all together, how much aggregate demand is there for these direct flights? Maybe if they only operate a 2-3 days a week they'd make sense.
Please add your thoughts on this topic...

Around Town: China's last narrow gauge passenger train
Posted byThanks so much for this article, Chris!
I've been meaning to ride this train ever since I first moved to Kunming almost 2 years ago (I used to live on 建设路 right next to the train tracks and waiting for it to cross was part of my daily routine). Being somewhat of a train geek myself, I'm embarrassed to say I never actually did it.
But seeing your article now, I'm inspired. In fact, this very afternoon, I think I'll go to the North Station and take the afternoon run to 石咀!
Myanmar drugs imperil Chinese border towns
Posted byTangentially related anecdote:
I've recently been watching a Chinese TV series called 军人荣誉.
It's entirely filmed on location in Yunnan, and centers around the 缉毒警察 (anti-narcotics armed police division) and their efforts to control the drug trade between Myanmar and Yunnan.
At times it's pretty cheesy, but also quite entertaining. Every few episodes there's a new story arc focusing on a different drug trafficking party. Usually there a beautiful girl, led down a path of personal destruction by some nightclub boss or gangster. We see flashbacks of the girl's life when she was still innocent and pure, and then see how she was corrupted.
Can hardly vouch for its authenticity, but thought it merited a mention on this thread.
You can find all the episodes on youku and tudou.
