Why didn't Yushan Bridge pass?

Vehicles transporting dangerous chemicals are prohibited from passing through Yushan Bridge. In addition, if the wind force in the area where the bridge is located is above 10, in order to avoid accidents, it is not allowed to close the bridge. At other times, the Yushan Island Bridge is allowed to pass.
