北京三元橋43小時完成改造!

　　A video clip featuring Chinese builders swapping out a bridge in downtown Beijing within 43 hours has gone viral on social media in China and abroad.

　　The two-minute time-lapse video recorded workers replacing the Sanyuanqiao cloverleaf junction.

　　The project started at around 11 pm on Nov 13 and ended on Nov 15. The most challenging part of the overhaul was the replacement of the 1,300-ton bridge structure, which cost RMB39m.

　　Many foreign viewers expressed their amazement at the "Chinese speed" and many asked whether this construction team does contract work overseas.

　　The footage garnered more than 1,680,000 views on YouTube by Tuesday.

　　克日，國表裏交際媒體網站上一段北都城區43小時"舊橋變新橋"的視頻敏捷躥紅。

　　這段兩分鐘的延時視頻記載了工人改換三元橋的進程。

　　工程於11月13日晚11點上下開啟，15日停止，最具挑釁性的部門便是1300噸橋梁的團體改換，耗資3900萬元。

　　很多外洋網友旁觀視頻後表達了對"中國速率"的驚嘆。許多人還問到這支工程隊是不是也承接外洋項目。

　　停止24日，這段視頻在YouTube網站播放量已跨越168萬。
