An aerial photo captures the construction site of the Jingkou Jialing River Bridge across the Jialing River, a critical component of a new high-speed railway linking Chengdu in southwest China’s Sichuan Province and its neighboring city Chongqing. The bridge was successfully joined yesterday, clearing a major hurdle for the official opening of the 292-kilometer line. As a backbone of China’s high-speed rail network, the rail line is the first railway engineered for speeds of up to 400 km/h, poised to become the fastest high-speed rail in the world. Xinhua
