China has had a series of large-scale infrastructure construction and mega-projects in recent years. Between 2005 and 2019 alone, more than 70,000 kilometers of expressways were added in China, and the total mileage opened to traffic reached 153,000 kilometers, currently ranking first in the world. China's total railway mileage also ranks second in the world at 150,000 kilometers.

 All this rapid development comes at a huge cost to the environment, communities get displaced many other social factors are ignored or bypassed.    Nevertheless their engineering excellence is truly impressive.  This is how a bridge is constructed everywhere nowadays ! But the height at which the bridge is being built beats logic . Maybe there is a mountain range on either side. But then normal engineers conscious of public money would have built it on the ground and drilled the shortest route tunnel.
