The main arches of a bridge at the junction of Southwest China's Yunnan, Guizhou and Sichuan provinces are joined on July 7, 2019. The bridge connects Xuyong county in Sichuan and Zhenxiong county in Yunnan, which are both national-level, poverty-stricken counties separated by a river. It takes two and a half hours by car or one and a half hours by boat – and a climb over mountains - to travel between the two counties. After the bridge is completed, travel time will be shortened to one minute by car. [Photo/Xinhua]
