Good article here on the rollicking Bridge Boom in China. Normally when a record is broken for longest bridge of steel/concrate/arch cantilever ...whatever... nowadays it is another Chinese bridge beating an earlier Chinese bridge of the same kind.

“The amount of high bridge construction in China is just insane,” said Eric Sakowski, an American bridge enthusiast who runs a website on the world’s highest bridges. “China’s opening, say, 50 high bridges a year, and the whole of the rest of the world combined might be opening 10.”


Of the world’s 100 highest bridges, 81 are in China, including some unfinished ones, according to Mr. Sakowski’s data.
He means road and rail both. I would dearly love to see the monsters on the Beipan River some day. However:

Quote:
The Chinese government estimated that expressways nationwide lost $47 billion in 2015, more than double the loss in 2014. In Hunan, expressways faced interest payments of $1.9 billion a year while taking in $1.3 billion in tolls, a deputy governor said in 2015.
and the high speed railway network which has many of the most massive bridges cannot be too flush either.

Surely the construction boom has to abate quickly, this lunacy cannot go on forever.

China is also building a Pingtang bridge which is a Millau Viaduct style homage across a valley in Guizhou.

It will be the tallest in the world by some measures. Flythru below.

This will be as long as the Millau but higher (and straighter therefore needing fewer towers).
