Aerial photo taken on April 22, 2019 shows the construction site of the Yuxi River Bridge on the Shangqiu-Hefei-Hangzhou high-speed railway in east China's Anhui Province. The closure of the two sections of the Yuxi River Bridge on Monday paved the way for the operation of the Shangqiu-Hefei-Hangzhou high-speed railway in 2020. The railway will link Shangqiu in central China's Henan Province, Hefei, capital of east China's Anhui Province, and Hangzhou, capital of east China's Zhejiang Province. (Xinhua/Liu Junxi)
