Workers set signs reading "road closed" at the entrance to the Nanjing Yangtze River Bridge in Nanjing, capital of east China's Jiangsu Province, Oct. 28, 2016. Nanjing Yangtze River Bridge was closed on Friday night for renovation after it was put into use for 48 years. The renovation project is planned to take 27 months. While the bridge is closed, vehicles can either use the second Nanjing Yangtze bridge, completed in 2001, or the tunnels below the river. (Xinhua/Sun Can)
