The typhoon is coming. Do you need a speed limit for the cross-sea bridge in Xiamen? Why?

When the typhoon comes, Xiamen's cross-sea bridge may need to speed limit. This is because when the typhoon comes, meteorological conditions may have an impact on the safety of the bridge. For example, strong wind or heavy rain may cause the bridge deck to freeze or be slippery, which will affect the driving safety of vehicles. In addition, if the structure or stability of the bridge is seriously affected by the typhoon, in order to ensure the safety and stability of the bridge, speed limit measures may also be taken.

According to the emergency plan for flood control and typhoon prevention in Xiamen, Haicang Bridge will be closed when the average wind force reaches 9. When the average wind force reaches 10, Xiamen Bridge, Jimei Bridge, Xinglin Bridge, Wuyuan Bridge, Yanwu Bridge and other bridges and Shugang Road Viaduct will be closed. This is to protect the lives and property of citizens under extreme weather conditions.
