Guangdong

Almost 500 kilometers of new expressway will open to traffic tomorrow in Guangdong province.

http://www.kaixian.tv/gd/2016/1227/82654.html

* S8: Guangfuzhao Expressway (Guangzhou / G55 - Guangxi border): 173 km
* G15W3: Yongguan Expressway (Chaozhou - Huidong): 129 + 55 km
* G2518: Shencen Expressway (Jiangmen / G15 - Luoding): 51 + 58 km
* S6 Guangjiang Expressway (a 'T' structure northeast of Jiangmen): 27 km

S8 is a completely new expressway that will run 221 km from Guangzhou to the Guangxi border near Fengkai. It follows the Xi River and contains several tunnels. The new segment runs from G55 west of Guangzhou to the Guangxi border, which is 173 km according to Google Earth. It passes by the city of Zhaoqing. It could be a part of the G6511 expressway from Liuzhou to Wuzhou in Guangxi, which Baidu shows as open.

G15W3 is the new expressway that runs parallel to G15 all the way from Ningbo to Dongguan. It incorporates the S20 expressway between Huidong/Huizhou and Dongguan. The newly opened segment runs from Chaozhou (not far from the Fujian border) to Huidong. However a segment from S17 to near Luhe already opened last year.

G2518, also known as provincial expressway S26 is supposed to run from Shenzhen to Cenxi in Guangxi. The newly opened segment runs from G15 west of Jiangmen to Luoding (it is also known as the Shenluo Expressway). Again, a segment from S5 to Xinxing already opened last year. This completes G2518 in Guangdong, at least west of the Pearl River Delta. I'm not sure if they actually plan to build the 40 or so kilometers from Shenzhen to Zhongshan, which would require a long bridge south of the Humen Bridge.

S6 is a new expressway that runs from Guangzhou to Jiangmen, in the southern part of the Pearl River Delta metropolis. It has many bridges, in fact 83% of the route runs on bridges. It consists of a 49 kilometer east-west route and an 18 kilometer north-south route through Jiangmen. It appears that the north-south route as well as 9 kilometers of the east-west route opens to traffic, they are not too clear on that. It makes sense as the bridge across the Xi River was far from completion on this satellite image from a year ago. The east-west and north south routes meet here.

I was intrigued by Chris' comment and wanted to find a highway plan of guangdong province. With my incredible paint skills and with the help of google translate I modified the one I found to be in english:



I don't think it's all accurate - the HK-macau bridge will surely not open in the next week but it might also be that Google translate was inaccurate in translating. However it seems Guangdong is preparing for a lot of construction in 2017 namely two Pearl River crossings and a northern Pearl River delta metro bypass. Obviously ignore the red line in the bottom left corner its the original authors addition but the rest seems accurate. I've checked a lot of the 2016-2017 projects and they all seem to be u/c as are some of the >2017 ones. Guangdong currently has 7000km of highways and the plan calls for more than 11000km by 2020 If Guangdong was a country it would probably be only behind China, USA, Spain, Germany and France. And those 11k don't include a lot of fully grade-separated urban highways.

The original image can be found here and if someone can provide more accurate translation please share them

http://big5.southcn.com/gate/big5/bb...qfrutgq30e.jpg

Edit: I found the original http://zwgk.gd.gov.cn/006939748/2013...08_374211.html. It seems to come from the provincial government of Guangdong province so that removes any doubt I had about the authenticity of the map.

It's an insane network of expressways. The Pearl River Delta already has by far the largest urban expressway network in the world, measuring over 3,000 kilometers and many more expressways are still being built.

Unlike say, Los Angeles, this area has very difficult topography, it's a giant river delta so almost all expressways require large bridges. Many expressways are elevated. But there are also mountains so there are quite a bit of tunnels as well, especially around Shenzhen and in the periphery.

What's interesting that they built this eight lane expressway in less than two years. February 2015 imagery in Google Earth shows no construction, and it's now open to traffic. It contains several bridges and two or three 4-tube tunnels. Apparently they couldn't build tubes large enough for four lanes in one direction.

Yunnan is crazy fast, they also built a metro line in two years .

About Guangdong's expressways, it's Guangfozhao expressway, as it is Foshan, not Fushan, much like Bengbu or Lu'an (both in Anhui) are not "Bangbu" or "Liu'an" respectively. But now it is clear it will go beyond Zhaoqing, so that invalidates its name, it should be the Guangfeng (Guangzhou-Fengkai) expressway. And yes, Chinese expressway plans are crazy, they are basically a "FritzOwling" of the whole country as they would be described over at AARoads forums, after a forumer named FritzOwl who has similarly crazy plans for the Western USA.

Oh, and I know Xi river as West river, as that is its literal meaning. And as a fact, the North Pan river, over which several high bridges have been built, flows into it through Hongshui, Qian and Xun rivers.

Maybe it's named after Zhaoqing prefecture, which continues past the city to the Guangxi border.

Amazing how they built a 61 kilometer expressway from June 2015 to December 2016, especially considering this is not easy terrain with several tunnels and a large number of bridges.

They could do that but it would take more time and additional difficulties during construction with probably more cost.
Chinese expressway construction is actually quite simple as they use same elements all over country (it's the same with their railways). Most viaducts, retaining walls and tunnels look the same. This simplifies things and makes them much cheaper and faster to build. Just special objects like some large bridges are made differently

The G2/S35 interchange. It looks like they also expanded G2 to eight lanes (February 2016 imagery in Google Earth shows four lanes).


Signage. Exit numbering appears quite commonly signed in China, though Baidu, OSM and Google maps do not show it.

I know that in western democracies infrastructure planning and construction requires far more burocracy than in PRC but... even if they look twice that time (3 years) it would have been extremely fast.
In Europe a such project would easily require a decade of construction.

I do not have a deep understanding of the procedures required to start construction of infrastructure in China, but if there are two countries in the world notorious for their ubiquitous, infinite and overall insane bureaucracy, these are Germany and China.

Well, I checked Baidu maps and it appears as the Guangzhou-Wuzhou (Guangwu) expressway (a route which G80 also does). And its number is S7 (although it doesn't have a number in the aforementioned map), S8 was the former number of the planned upgrade of G107, now part of G4W2.

A standard stretch of motorway under normal circumstances takes 3-4 years to physically construct in Canada.. 8-10 years in the full process from idea inception to completion, maybe. 3-4 years of initial Planning, 2-3 for detailed design and tendering, and 3-4 for construction.

My understanding is that the planning process in china is more like 1-2 years instead of 6-7, with construction being 2-3 instead of 3-4.

2.5 - 3.5 years seems quite common for most Chinese expressway projects that do not require exceptional bridges or tunnels. A construction time of less than 2 years does occur (as is evidently the case in Yunnan), but doesn't seem like commonplace in all regions.

For example, today a 134 kilometer segment of G7 (Jingxin Expressway) was inaugurated in northern Gansu. It runs from the Inner Mongolia border to the Xinjiang border. It runs through fairly flat terrain, no major bridges or tunnels are required. Construction lasted from June 2014 to December 2016.

The "Middle of nowhere expressway" as I call it. The largest (and only) settlement along the route is the village (cun) of Gongpoquan, seat of the town (zhen) of Mazongshan, located in the autonomous county (zizhixian) of Subei Mongol in the city (shi) of Jiuquan. In the Subway and Urban Transport forums they ask where lesser known cities are located, I even know of villages like that one!

Chengdu

There is even a third ring expressway of Chengdu under construction. It will be a 438 km (Chinese Wikipedia) or 459 km (Baike) long ring road.

The southern half from G5 at Pujiang to the newly opened G5013 near Jianyang (127 km) could open by 1 January 2017 according to this report, which is a bit vague to me: http://meishan.scol.com.cn/sdxw/201612/55787597.html

Google Earth shows advanced construction on this segment. Baidu labels it as G4203. Chinese Wikipedia doesn't show a number for this portion, but notes that the northern half is numbered as G0511.

Chinese Wikipedia: https://zh.wikipedia.org/wiki/%E6%88...85%AC%E8%B7%AF

I knew about that mega-ring for some time now. I've seen G4203 as a number for all of it, but actually only the Deyang-Dujiangyan section has an "official" number, that being G0511 (And of course, it's named Deyang-Dujiangyan, or Dedu, expressway). Baidu shows another G0511 North of Linfen in Shanxi, which I've also seen listed as S73 in the English Wikipedia.

There are several mega ring roads in China. These typically have a more regional character than a functional bypass of a city.

* G93: Chengyu Ring Expressway in Sichuan & Chongqing. Planned length of 1057 kilometers.
* G95: Capital Area Expressway around Beijing. Planned length of 924 kilometers.
* G98: Ring Expressway (Hainan). 613 kilometers.
* G91: Liaozhong Ring Expressway around Shenyang. Length of 399 kilometers.
* G94: Zhusanjiao Ring Expressway around the Pearl River Delta. Planned length of 338 kilometers.
* G92: Hangzhouwan Ring Expressway around the Hangzhou Bay. Planned length of 229 kilometers.

Many city ring roads are numbered concurrent with other expressways. Some only have small segments that are not part of another route.
