World's longest cross-sea highway & rail-bridge

The photo taken on October 8, 2019, shows the world's longest cross-sea bridge - Pingtan cross-strait road-rail bridge - located in Fujian Province. The 16-kilometer bridge, linking Songxia County with Pingtan Island, is expected to open next year. The upper layer is a highway which allows vehicles to run up to 100 kilometers per hour, and the lower layer is for rail transport and allows trains to go as fast as 200 kilometers per hour.
