Why are they constructing giant freeways in the middle of mountains and deserts, but at the same time f.e. Beijing expressways are in the city completely sub-standard?! Just like in Spain...

China is very mountainous and it's common that the roads are constructed in the middle of mountains.
Maybe because the heavy traffic overloaded the expressways in Beijing.

Well many of Beijings ringroads even cant be called expressways with traffic light and very poor engineering, while I've seen tons of pics of totally empty superhighways in the middle of deserts and mountainois areas with _no_ populations.

In areas with no population, land is free to government, in Beijing, more political trouble for them to demolish buildings, etc.

Are you kidding? I live in Beijing for 5 years and never seen a ring road with "traffic light and very poor engineering". Point out ONE if you don't mind.

Again except for the opening period tell me which expressway is totally empty? I just came back from the west for Chinese New Year and what I saw is heavy traffic for most of the expressways.

Either the other guy is talking crap or he just assumed that Google Maps was right by showing the inner ring roads yellow instead of orange, but they're all still grade-seperated.

G3012 through the desert in the far west maybe? I dunno... But what also should be noted is that not all highways are built because it is too busy for a regular road, but also for safety reasons. With building a highway you basically eliminate head-on crashes (besides of course some nutjob every now and then that will use the wrong carriageway...) whilst it's quite easy to have them on roads where traffic in both directions is only seperated by a simple white line. Also the average speed. You can go faster on a highway than over regular roads. Which, with the huge distances in for example the west of China would give great time gains against relatively low cost. And those are just 2 examples of the advantages that highways have over regular roads.

I imagine the inner ring roads (2 and 3) might be more challenging for keeping typical expressway standards but 'traffic lights' and 'poor engineering' made me think wtf is this guy talking about.

Anyway, it's all covered by Tencent or Baidu Maps Streetview so we can actually have a look and have a virtual tour.

If you are reduced to drawing inferences from images instead of first hand experience draws attention to your judgement of lack thereof.

Obviously 1.384 billion people crammed along the eastern seaboard manily wouldn't impress you enough . I heard people say many things about China but you are the first to infer that it seems under populated.

By way of comparision exactly how many billions of people live in your crowded part of the World?

Shocked to see this China being the third largest country in the world is at number 6 in the list of World Longest Highways.. and when compared to United states it too less, United States is next to China in the list of biggest countries

United States Pan American Highway : 48,000km.
China National Highway 010 : 5,700km

See the difference its more than 42000 KM...

China - Worlds third biggest in terms of Area and first in population has a much need of Highways

Your figure for the Pan-American Highway seems far too high, even including spurs and branches in all 23 countries. For comparison, the longitudinal distance across the earth's surface from pole to pole is about 20,000 km.

The G-000 series of National Highways (five vertical and seven horizontal expressways) has been replaced in favor of the so-called 7918 system (7 radial expressways from Beijing, 9 north-south and 18 east-west) with G numbers of one, two or four digits. See http://en.wikipedia.org/wiki/Express...List_by_number

Agree, it's only a game of numbering. And it's worth to mention that in US and China, highway = expressway, where in some countries highway could be lower grade roads, i.e. without proper access control.

Even G3012 being a desert expressway is far from being called "totally empty" after the opening period.

Wait wait wait, I'm not dissing China in any way and don't have anything against the chinese?! I just remember seeing pictures on Beijings inner ringroads with stops, straight accesses to little streets and really badly built interchanges, and a few pages ago there is an nearly totally empty desert highway with not a house in hundreds of kilometres. I just think now that there still is money China should focus on it's cities highway network. The bridges on the mountains are awesome, but also really expensive compared to their cost (AADT like 1000-3000?); the job they are doing is really great, but priorities should go first - China has still the opportunity to built proper urban motorways as people think about progress and not their backyards like in Europe. For example, what is the AADT of the G638 Lianhuo Expwy in the middle of the desert, 100?

There is no G010 anymore. That has been replaced mostly by G15. There is a G10, though, which is nowhere near that lenght.

Actually the system is now being called 71118, with 11 north-south expressways after the addition of G59 and G69. Anyway, I think I can come up with a new grid.

FTFY. Anyway, I believe it is not less than 1000.

Chris sometimes complained about some names that despite being written differently in hanzi (Chinese characters) got rendered the same in Hanyu Pinyin, the most notable case being Shanxi and Shaanxi (The latter is from Gwoyeu Romatzyh, in Hanyu Pinyin is... Shanxi!). But I've found the real nightmare, two expressways sharing number and name even in hanzi: S48 沪宜高速 Huyi expressway, found in both Hubei and Jiangsu. The Hubei expressway is more like a branch of G50 Huyu expressway into Yichang, and continues to the Three Gorges dam as S58 Sanxia expressway, while the one in Jiangsu runs from Taicang (With a probable extension into Northern Shanghai still missing) to Yixing, but it has a gap North of Suzhou and Wuxi.

It seems, on my far away view, China has some big problems with traffic during holidays though when everything goes crazy, so some "oversize" highways are necessary in rural places... plus, the old roads are often clearly useless for even that traffic (too narrow, no pavement, between houses...), and if you are going to blow up a mountain to pass a new road, or you are building a road through desert, 4 lanes is as much work as 2 lanes The political system is such also that priorities are not set necessarily in a logical way (insufficient opposition)...

That said we see in this thread pictures of a lot of urban infrastructure not adapted to traffic, like insane traffic jams on an interchange, or interchange with super-elevated loops (why not just a stack interchange if already spending money to put loops on viaducts?!)
