With a grand arch bridge erected on Monday morning, Chinese constructors have built the longest-spanning railway arch bridge with a single span of 490 meters. The bridge is a key project of the 220-km-long Dali-Ruili railway which is a key section of the China-Myanmar international railway corridor linking Kunming, the provincial capital of Yunnan, with Yangon of Myanmar.
