Take a look at the world's largest span suspension bridge in a mountainous region! The Jinsha River Bridge has a main span of 1,386 meters, and the height between the bridge deck and the valley floor is 335 meters. Since its opening to traffic in 2021, it only takes one minute to drive across the Jinsha River, a journey which used to take an hour. What changes has it brought to the local area? Join CGTN's Xu Xinchen to take a look.
