Construction of the world's largest span suspension bridge, the Jin'an-Jinsha River Bridge, was successfully finished in Southwest China's Yunnan province on Wednesday, marking the completion of the key main structures of the bridge and laying a solid foundation for the completion of the Huaping-Lijiang Expressway.

The construction of the steel truss suspension bridge, an important part of the Huaping-Lijiang Expressway project, was made with highly technical difficulty due to the area's high earthquake risk and high altitude.

The main span of the bridge is 1,386 meters, and the vertical difference between the bridge surface and the river's surface in the valley below is 330 meters.
