What do the different coloured lines mean?

And Europe, to some extend, too. Although it differs from place to place, most motorways in western Europe were also constructed between the 1950's and 1980's. But they've just started a real motorway network in central Europe from the 1990's mostly.

China's expressway plan is called 7918 network, which indicates,

7 Beijing radiation lines (yellow)
9 North-South vertical lines (Green)
18 East-West horizontal lines (Blue)

The thin lines are connection lines, i.e. thin green lines are vertical connection lines.

The brown color lines are city ring roads.

Originally all lines on the map are green/blue/yellow color. To show the construction status, all the finished expressways were filled with red color. so now you see in the map most lines are red no matter it's vertical, horizontal ot radiation lines.

I see, thanks. So it's possible now to drive across China to Kazakhstan over expy's now. How does this road continue in Kazakhstan? Also as an expy?

not sure about the road conditions in Kazakhstan, but even the Chinese part is not all finished. you can see there's quite some distance in the west part of the map marked as yellow color (radiation line but not finished).

It seems like you can get there with the (red) expy running south of it, but that seems like a big detour when you live in Beijing

Even that isn't complete, if you look closely. Some parts of it are blue.

Yeah, but just some very small sections. There is an expy border with Kazakhstan though. Does anyone have pics of this border crossing?

Looking closer at that map, some lines are thicker than others and there are two different shades of red. What do the thickness and shade of a red line mean?

Probably 2×3 instead of 2×2

I have no clue on the shades. The thick lines means backbone 7918 network lines while thin lines are connection lines.

If I get it right, CN is the two-letter code of PR China. China hasn't reported its oval code, but it's said to be PRC, not CN. If you look in references in that wiki link, PR China isn't mentioned, while several sources, like this one, claim it to be PRC.

So, I think we can generally conclude China doesn't have an official oval at all.

CN or PRC looks both good to me.

I've said this before, but again, very impressive thread! China's infrastructure projects are very intriguing, not even just because of their sheer size.

Google Maps now show the current traffic flows at all the major arteries in many Chinese cities. Most of it is in Chinese, but just navigate to your city of choice and make sure to click the "Traffic"-button in the upper right part of the map window.

Btw, the maps also show all metro lines and bus stops in the cities.

But the expressway is very important income for local govt., so the local officials try hard to get the way tolled forever.

for example, the first chinese expressway is shenda in 1989, so it would be freeway in 2004. In 2003, Governor BoXilai order to extend the 2 lanes X2 to 3 lanes X2. Project was completed in 2004, so they can tolled in this way until 2019.
