Hangzhou Bay Cross-sea Bridge

This time, we drove from Zhoushan Islands to Putuo Mountain and then back to Shanghai. The longest cross-sea bridge we passed was the Hangzhou Bay Cross-sea Bridge. We drove on the bridge for more than half an hour. While driving, we found that there was a lot of siltation at the head and end of the bridge. Only the bridge was left. The surrounding water conditions are relatively good, and I feel that boats can sail within this range. It reminds me of what will happen to the sediment when the Qiantang River surges inward every year.
