When you have a billion people willing to work instead of expecting free "stuff", anything's possible... Earlier this year, a Chinese construction company had erected a 57-story skyscraper in just 19 days [3]. This time the Chinese have built an overpass in mere 43 hours!
Workers took apart the old structure of Beijing's Sanyuan Bridge in a few hours. Then they brought an entire piece of concrete to bridge the gap and paved it over, reports Citylab.com.
To build the bridge, over 1300 tonnes of new surfacing material was used which save months of commotion and traffic woes. For the first time in Chinese workers tried out a new 'integrated replacement method.'
