Openning all of these expressways in one day? It`s incredible
How is the total length of expressways at the beginning of 2017 in China?

Approximately 130,000 kilometers.

Based on information so far (china-highway & google news search) I found 2770 kilometers of expressway to have opened over the past week.

Looks like G4 at the Hebei-Beijing border.

A video detailing the Beipanjiang Bridge of the Shuipan Expressway (S77) in Guizhou province.

In addition to being a very high bridge, it is also one of the longest spans of this type, according to Wikipedia, the longest concrete cantilever / box girder span is 301 meters in Norway, but this website lists a 330 meter box girder span in Chongqing.

A video of the Fuma Bridge across the Yangtze, near Wanzhou, Chongqing.



Fuma Yangtze River bridge,main span 1050m, deck high 185m from water. It is one of ten high bridges in China which has more than 1000m span, also the only 6 lane large suspension bridge more than 100m high

I suppose this will be a part of the G69 Yinbai Expressway.

G50 Huyu Expressway

G50 / Huyu Expressway (also known as the Shanghai - Chongqing Expressway) runs through very mountainous terrain in western Hubei. This is the area south of the Yangtze River and its three gorges.

It was the first east-west expressway into the Sichuan basin to be completed. The Yichang - Enshi segment of G50 contains several very high bridges.


1. Weijiazhou Bridge (220 meter high, 200 meter span)


2. Tieluoping Bridge (209 meter high, 322 meter span)


3. Zhijinge Bridge (294 meter high, 430 meter span, highest arch bridge for road traffic in the world)


4. Siduhe Bridge (496 meter high, 900 meter span, world's highest bridge 2009-2015).


5. Mashuihe Bridge (219 meter high, 200 meter span)


There is also a 13 kilometer segment with 5 bridges of nearly 200 meters or higher.

Hainan

I wonder why they haven't built a bridge to the island/province of Hainan yet. It would be a long bridge (circa 20 kilometers), but that has been done before. It seems more realistic than a 100 kilometer tunnel under the Bohai Sea or a tunnel to Taiwan. And it makes economically more sense than an expressway from Sichuan to Tibet or an expressway from Lhasa to Kargilik through the Himalayas and Karakoram.

G30 Lianhuo Expressway

An 820 kilometer segment of G30 Lianhuo Expressway has been nearly entirely expanded to eight lanes in Henan and Shaanxi provinces between 2010 and 2015. Only the Xi'an Ring Road has not been expanded (though a new G30N bypass with six lanes has been built).

G4 is now eight lanes from the Beijing/Hebei border all the way to the Henan/Hubei one, a whooping 955 km . If we count the section with six or more lanes, which is from the very beginning of the Beijing-Hong Kong-Macau expressway, it hits the megameter (1000 km) mark.

Even worse, they have already built several 30+ km bridges, like the Donghai, the first Hangzhou Bay, or the Jiaozhou Bay ones. If they haven't built the fixed link to Hainan, the typhoons that ocassionally hit the area may explain why.

I've looked at sea depth in GE and to Hainan sea bed is at least 80 meters deep in some parts and more than 60 meters for considerable lenght. Sea beds at currently built (or being built) bridges in China are all just 10-20 meters deep at most. Even to Taiwan sea bed is up to 60 meters deep. So that is surely some reason for delaying bridge/tunnel construction. It is possible to build but is more complicated and more expensive.
Another reason is that there are no big cities on mainland China in this region so there is not enough potential traffic. That can be seen at ferry ports as they look like pretty small and basic. Hainan is mostly a tourist island where almost arrive with planes and will do that in the future as it is faster and cheaper.

Define " Big", the PRD isn't far away and with the advent of the HSR network a whole host of cities can be accessed .

The real issue is priority, how much priority any such project is given in Beijing in comparision to other big ticket infrastructure projects .

Some of the other projects you mention have importance in terms of national economic development, while an expressway thru seemingly remote areas doesn't make sense looking at a map from afar they make a huge difference on the ground to those communities economically it allows the movement of goods in both directions enabling producers to get their produce to markets to sell at a good profit hence raising their material standard of living and the extra disposable income helps fuel the local service sector . The spin off benefits are many. All exressways in the western region will eventually form part of the silk road and iron silk road trading routes . In economic terms the whole continent could be better off . Never look at infrastructure development in China in isolation, soley in terms of single projects vs other single projects.

It's not an expressway between western Sichuan and Tibet but part of the expressway between Beijing and Tehran or Shanghai and London. In that context all these missing links are vitally important.

Zhanjiang has an urban population of 1.1 million. Hainan has a population of 9 million.

On CCTV they said that the Beipanjiang Bridge traffic is forecasted at 3,000 vehicles per day. That's quite low for such an expense, and the traffic potential here is surely much bigger than a link from Sichuan to Lhasa.

And has exactly 3 motorway exists from standard 4-lane expressway and one interchange. Economic power of that area is not even remotely comparable to those around Shanghai, Hongkong, Quanzhou or Hangzhou, where those long bridges are.
But I believe the main reason for bridge construction delay is a fact that constructing a 10+ km long bridge over 60-80 m deep water is technologically much more complex than really long bridges over mostly 10 m deep water. It is not impossible, it is just complex and expensive. Probably they encountered some serious technological problems when designing a bridge.

It is difficult to find total heights of deeper water bridges as heights are usually measured or shown from the water table.

This is a typical situation for Chinese cities of this size. Unlike Europe, expressways are running fairly far outside the city and only serve it with a few exits, as expressways are mostly geared for long-distance travel and not for commuting except for the largest metropolises.

Sure, but the same can be said of the expressway construction in remote mountain areas where motorways in the Alps look like child's play. Guizhou is not an economic powerhouse either but has 5400 kilometers of expressway and more high bridges than all other countries of the world combined. So current economic standards is not an indicator of infrastructure need in China.

Chinese expressway length

I have not yet found any official / unofficial data of the 31/12/2016 length of the Chinese expressway network, other than 'around 130,000 km'.

However several provinces posted their end-of-year expressway totals;

* Guangdong: 7673 km
* Guanxi: 4656 km
* Guizhou: 5433 km
* Jiangxi: 5908 km
* Shaanxi: 5279 km
* Shandong: 5710 km

Pretty similar to the US 19 bridge through the Appalachian mountians. I've driven over that one several times, and it is massive with an incredible view. Its "only" 267m above the bottom of the valley however. The span is longer though, at 518m.

China opened 1370 kilometers of new expressway in January, which is quite a large number, usually they open most of it in December. Jiangxi province was responsible for half of that figure, but there was a sizable amount of expressways to open elsewhere in China.
