Good thing that it all got built regardless. Top-notch infrastructure is great to have and it will surely be maintained as well or better than the US' extensive system is so I'm not terribly worried.

Nice commercial with the G5 expressway (Ya'an - Xichang) and its chief designer.

Xinghai Bay Bridge, Dalian

The Xinghai Bay Bridge in Dalian opened to traffic on 30 October 2015.

It is a 6 kilometer long cross-sea bridge, the first suspension bridge in China which is anchored on the sea bed instead of land. The suspension bridge is not particularly long, at #99 in the world according to Chinese Wikipedia. The main span length is 460 meters.

It is a double-deck, eight-lane bridge that crosses the Xinghai Bay. It was built from 2010 to 2015 and the project also included a 3 kilometer long six-lane tunnel east of the bridge.

Is there some engineering reason why a bridge like this is not built in a straight line? Or perhaps the depth of water is very uneven in that place?

Duge Beipanjiang Bridge

The world's highest bridge is being built across the Beipan River near Duge, on the border of Guizhou and Yunnan. It is part of the G56 expressway. Just 10 kilometers away is the 485 meter high Puli Bridge that was completed last year. However, the Duge Bridge will be substantially higher with a deck at 564 meters above the valley floor. Both bridges will open to traffic in October 2016.

An eight lane tunnel through solid rocks is very expensive.


See bridge @ 0:39

That crossed my mind too. It's very similar, though the Dalian Bridge seems a bit longer overall.

I think it's also built as a monument to showcase development rather than solely as a infrastructure thing.

A render of a large suspension bridge under construction across the Yangtze River east of Zhenjiang in Jiangsu province.

The main span is 1092 meters, not particularly record-like. However, it will be a double-deck suspension bridge, with 8 lanes and 4 rail tracks. It is considered the heaviest bearing suspension bridge in the world. Completion is planned for 2020.

There are expressways in China through much more difficult terrain than this expressway near Lhasa. Think of Guizhou, Shanxi, Yunnan, northern Hebei or the coastal infrastructure.

"We built up the road along the Nyang River valley, a geologic hazard-prone area. It's common to encounter landslides, mudslides, rockslides, soft soil and frozen soil. And bridges occupies 15 percent of the whole road. ...

After repeated trials, they succeeded in creating a new material. For the first time in the plateau highway construction, the anti-cracking fabric was applied to the pavement, and has so far, yielded good results. ...

The construction budget totals 38 billion yuan, which is more than 6.1 billion US dollars. The highway is expected to cover nearly 410 kilometers, with the speed reaching 80 kilometers per hour on four lanes.

Soon we'll see abandoned projects that soon will be forgotten in a giant country like China, empty 4+4+4+4+4+4-lane 540 m viaduct-height-motorways in Tibet and cities more congested than ever because as in the list we can see, big cities have been badly neglected, specially Beijing. It so reminds me of Spain 2008... Impressive of course but still.
