Pingtang Bridge in southwest China's Guizhou Province has the highest concrete bridge tower in the world. The tower is 332 meters high, as tall as a 110-floor building. The bridge, a colossal cable-supported viaduct that spans 2,135 meters across a canyon, serves as a major connection on the Pingtang-Luodian Expressway. Since the bridge opened to traffic in Dec. 2019, it has reduced the travel time between Pingtang and Luodian from over two and a half hours to about one hour.
