China should continue the hk Macau zhuhai bridge by building one to hainan. Then one bridge to Taiwan.
This 123km Bo Hai Bay 渤海湾 between Dalian 大连 <-> Yan Tai 烟台 I can see it as a stepping stone for the next one to Taiwan which is about 141km if made between Tao Yuan (near Taipei International Airport) 桃源 <-> Ping Tan 平潭 Island.
The 1st 123km one is shorter and easier because the north usually don't get strong typhoon. Taiwan gets lots of typhoon yearly plus many earthquakes yearly.
To build anything must be made typhoon proof and quake proof. Or else fuck spider.
The north seldom have such strong natural deserters. But once in a fucking century may get 唐山大地震, 9.x scale one, TUA TUA KEE.
