The closure of the main section of the Yuanjiang Railway Bridge is complete. This bridge is considered one of the more challenging projects on the China-Laos railway. The bridge girder spans 249 meters, which is a world record. It is designed to be 832.2 meters long and supported by six piers, with the tallest standing at 154 meters. With a total length of over 1,000 kilometers, the line will be put into operation by the end of 2021. After the train service is launched, visitors will be able to take overnight trains to Vientiane, Laos, from Kunming City in southwest China.
