China is hailed as an "infrastructure maniac" for its dazzling array of mega projects constructed at amazing speed.

"China's progress in advanced infrastructure is more than 100 times faster than the US," Tesla CEO Elon Musk commented in a tweet after he saw news that reported on how Chinese workers managed to upgrade a railway station within nine hours.

Meanwhile, in Shanghai, the construction of an 8-kilometer stretch of road has been continuing, off and on, for decades. On Monday, Pudong Avenue finally opened to traffic.
