Filling some gaps in the network .

How came this section wasn't built yet despite being the closest to a big city like Kunming? BTW, the original plan for G5 is now complete. G5 was originally planned to start on a long concurrency, first with G4 from Beijing to Shijiazhuang and then with G20 to Taiyuan, but now a new alignement is being built. Same goes to the G2/G3 pair to Tai'an in Shandong and the G6/G7 pair up to Hohhot (But this pair will still be concurrent till Bayannur).

Another thing is the NW part of the Kunming ring road (G8501), which is shown in a more advanced stage in the satellite view than G5 but apparently isn't open yet.

For some reason I though they would use the already existing Yangtze crossing instead of the newly built one.

Yeah, this gap was a eyesore, at least in Google Maps. Actually there is still a section missing, the Easternmost Hunan section from Jiangxi border to Chaling, although this gap is brigded a few kilometers to the South.

I figured out that the G72 gap is bridged by what is going to become G4E and G1517.

Anyway, it seems that Google has had an imagery update lately, and I've found some new expressways U/C:

G5 in Beijing! Finally. Now I know exactly where it will meet the G4501 6th ring road.

G7 Middle of Nowhere expressway (I gave it this name because of the planned section from Linhe to Hami, which literally passes through nothing) in Inner Mongolia, from Shanxi to Hohhot. Finally I figured out what was that unknown expressway U/C Northeast of Hohhot -_-. It will clip the northernmost tip of Shanxi unlike its sister G6, which misses it just before crossing from Hebei to Inner Mongolia, and in this eight km trek the G7 will have an autobahndreieck! Shanxi S45 is U/C up to there.

G10 as far west as Hailar.

G3012 between Aksu and Kashgar.

G5601, Kunming ring road. In addition to the well visible Northwestern part, I've found a part of the Southeastern section U/C. There is also an extension of the expressway in Eastern Kunming labelled "Ring expy" through the South of the city, but it connects to G56 too close to the city core, so this is not part of the G5601. I've found another expressway U/C running by the new airport. Knowing how Chinese are allergic to concurrencies, this may be well a reroute of either G56, G60, or G85.

Spectacular expressway above, needs to be driven some day.

However it seems that drivers don't like much right lane.

Brutal blizzards seem to be possible in Inner Mongolia. This is G10 under construction in early 2013.

A new expressway will be built to connect Kunming and Songming County as well as the International Airport Economic Area, the Kunming Economic and Technological Development Zone, the South and Southeast Asia Synthetic Logistics Center, and the new urban district of Chenggong.

The 56.89km-long expressway is a four-lane highway with a designed speed of 100 kmph. It includes six overpasses, an integrated service area and a parking lot, with an estimated investment of 7.475 billion yuan. The construction is expected to be completed by 2016.

It is said that the expressway is an important part of Chongqing-Kunming Highway linking Kunming, Qujing and Yuxi, and the main fast road connecting Kunming's northeast part and main urban area.

"The new expressway will ease traffic pressure on the present Kunming-Songming Highway. Besides, the travel time from the new expressway to the Kunming Changshui International Airport will be shortened to about 20 minutes," an insider said.

The airport is located in the northeast of Kunming and the distance between the county seat of Songming. The airport is just 14 kilometers, but drivers have to pass round the Kunming--Qujing Expressway and then run through the Airport Expressway, which takes more than one hour. (Editors: Ryan Li, Lynn)

Two very scenic expressways:

G30 in west Xinjiang


G5 in Sichuan

An expressway connecting Kunming Changshui International Airport and Guantong Town in Lufeng County, will be constructed.

The expressway is planned to connect Kunming--Qujing Expressway, Northwest Ring Expressway, Wuding--Kunming Expressway and Wuding--Yimen Expressway that is scheduled to be built in central Yunnan.

The road will total 136.4 kilometers and will include three sections: the first section, two-way six-lane, connects the airport and Qinfeng Town, in the east of Lufeng County. The second section is an eight-lane freeway linking Qinfeng and Lufeng. The speed of the above two sections is designed to be 100km/h. The third section is a six-lane expressway, from Lufeng to Guangtong. The designed speed is 80km/m.

So far, Guangtong, about 159 kilometers from Kunming, has been developed into a distribution center for sugars, fertilizers, teas, fruits, vegetables and minerals in the western Yunnan. (Editors:Lynn, Tracy)

Why S0311 cannot overlap G70? The last county before the border is Jianning, so I believe this is part of S0311 Pujian expressway.

A 39 kilometer stretch of the Ring Expressway of Kunming (Yunnan province) opens to traffic. It runs from the recently opened G5 to G56 northwest and west of the city. The expressway has six lanes and several tunnels.
As I said before, I tought this would open before G5.

Knowing Shanxi's numbering system, this could be numbered with an odd number between S30 and S46. I lean towards S40.

A circa 20 kilometer segment of G56 Hangrui Expressway opens in eastern Yunnan province. It runs from Tongren-Daxing Airport at the border with Guizhou to Tongren-North.
A correction: it's Eastern Guizhou, not Yunnan. And the border is with Hunan.

Actually is slated to be extended to Lubei, labelled as Jarud (banner) in Google Maps. And in the long term is planned to go even further to Huolin Gol, but with another number (G2515). I don't like whole routes with a number change halfway, like Austrian A10/A11 or French A71/A75.

One detail: It's going to be numbered G50S.

China's central median and barriers are FAR too close to the outside lane... there's literally no room to maneuver in an emergancy.

The lanes look pretty narrow too

Many Chinese 2x2 expressways have a cross-section of 24.5 meters wide, which is narrower than most European motorways. For example the German Autobahn has a cross-section of 31.0 m standard and 28.0 m narrow (25.0 m for urban expressways).

Google Maps is about to update, as one can route through some expressways that aren't in the map yet. Basically anything that has been open for a year now will appear in some days, including the G40 realignement in Shaanxi, the G55 from Sonid left banner to Chahar back left banner, and the S2013, S20 (future G0612) and G3011 through Qinghai. Now is clear that G6 will follow G109 through central Qinghai.

Funny effect of the Chongqi Bridge (G40) near Shanghai on the northern fork of the Yangtze.

Not good for safety IMO...

Are newer express ways built to these standards?

I think Chinese expressways are originally based off Japanese expressways. What is the cross section of Japanese expressways?

I am in favor of narrow cross section because it saves land, but now China is doing a lot of land-wasting types of development, so there wasn't really much point. I hate huge space-wasting medians with grass though.

Those green belts were designed as space for future expansions.

Jinpingshan Tunnel

We were talking about the longest tunnels in the Bulgarian road thread, and the Jinpingshan Tunnel was pointed out as being an unknown long tunnel.

The Jinpingshan Tunnel, or Jinping Mountain Tunnel ( 锦屏山隧道 ), is a 17.5 km twin-tube tunnel in southern Sichuan. It allows access to the new Jinping Dam, a 305 meter tall arch dam, currently the tallest in the world.

Not only did they construct two road tunnel tubes, but they also bored 4 water tunnels for power generation. The tubes are 17,485 m and 17,504 meters long. Both have one lane and a narrow shoulder. It only serves traffic to and from the Jinping Dam, it is not on any numbered road and is not shown on either Google Maps or Open Street Map. The tunnel lies a maximum of 2,375 meters below the surface (second deepest in the world).

Approximate location:

AFAIK they are planning an expressway (the G7611 from the new plan) through that area. Surely it will be spectacular. By the way, I believe OSM is facing some legal issues in China, so it won't be mapped soon.

Obviously not the Rongwu, as Google Maps updated today and G18 appeared south of where this new expressway runs. It could be the same expressway as the section that opened a few days ago, but it would imply a wrong-way concurrency with G18.

I read somewhere that the number of this ring expressway is S1202, i.e. a spur of SG12.
