Recently I've seen some mistakes in Google Maps. Around Qingzhou, Shandong; and near Huizhou, Guangdong; there are routes numbered Gxx, like national expressways, and Google got confused and put national expressways shields to they. Here is a list:
Near Qingzhou:
G03 Jingtai expressway
G33
G39
G40 Hushaan expressway
G76 Quannan expressway
G77
G78 Shankun expressway
G79
G80 Guangkun expressway
G81
G82

And near Huizhou:
G22 Qinglan expressway
G29
G33 (Again)
G35 Jiguang expressway (Even if the actual expressway lies to the Northwest)
G45 Daguang expressway
G54
G55 Erguang expressway
G68
G78 Shankun expressway (Again)
G88

I would like to ask what are the average construction times of a motorway sections. Let's say depending on the conditions... easy plain terrain, terrain with heaps and cities, mountainous terrain.

I think there must be now enourmous amount of machienery and heavy building systems for motorway constructions. These once invested, should last for some years before depreciated. With construction scale like the one in China, the construction companies should invest heavily in the machienery in the beggining years. Now and for the rest their costs should be mainly in the cheap labour and construction materials. This further driving the price of construction down.

Easy put, the economies of scale seems to be so huge in China that they should drive the prices very low and construction speed up. Are there some new breaktrhough techniuqes used in China in the construction? Some semi automated motorway construction, huge machines, lots of prefabricated work, etc...

I am not familiar with this field so therefore my "naive" questions but thanks for any information on this topic and pictures .

You have to keep in mind China is a huge country with 1.3 billion inhabitants. Its current construction pace is not faster than the U.S. did in the 1960's and 1970's, on a per-capita basis.

Most expressways in China are constructed in 2.5 - 3 years, similar to Europe if full funding is available (i.e. not countries like Germany or Switzerland).

Ok, thanks for the answer. Thus no marvells?

But the technology is now bit further then in 1960. Things like gps, lasers, etc are a game changer I think. And the chinese are doing this in the same time with constructing the biggest HSR in the world and also huge network "ordinary"" 160 km/h train lines.


Things like this video impress me rather lot and begins me thinking about what is possible...



Will we there be once a machine swallowing the soil on one side and spitting out the asphallt on the othe (joking for sure, but we can get close to this, e.g giant excavaters with conveyers belts etc..., excavating the whole motorway continuosly from point A to point B etc.. or building the whole motorway on the piles going from A to B, I dont really know what is possible).

G5 Jingkun Expressway

Next Saturday, April 28th, the last section of the G5 Jingkun Expressway in Sichuan province will open to traffic. This section is about 160 kilometers long and runs through mountainous terrain.

Very interesting is this tunnel/viaduct spiral to climb 250 meters.

this might be a stupid question, but is that steel structure the final load-bearing thingie?

Apparently it is. It's some sort of world-record bridge type, this is what Google Translate makes of it:

Yesterday, Iasi highway Ganhaizi Bridge officially completed, which is the world's longest steel pipe truss girder highway bridge, a major breakthrough for the research and construction of highway bridge construction, marking China's dangerous mountain.

Regarding the steel pipe construction, are the pipes filled with concrete? I recall that construction method being used to build arch bridges in China, a technique that China invented.

4.28 Beijing-Kunming expressway project finished its Sichuan section, the most difficult part, which marks the completion of the majority part of the 2860km expressway.

Great photos. Some of them with the older road next to the new highway summarizes the leap in infrastructure development happened in last decade. Crazy..

Perhaps no, but definitely more environment friendly then digging on the hillside.
