The Danyang-Kunshan is mainly over land. It's an elevated railway line. It does cross the Yangcheng Lake, but that part is only 9km long. It's not a suspended bridge, there are piles every 80m. Not suitable for heavy maritime traffic. The lake has an average depth of 2m. https://www.lakepedia.com/lake/yangcheng.html https://www.lakepedia.com/lake/yangcheng.html It's not comparable as a channel crossing. https://en.wikipedia.org/wiki/Danyang%E2%80%93Kunshan_Grand_Bridge https://en.wikipedia.org/wiki/Danyang%E2%80%93Kunshan_Grand_... Likewise the depth of Jiaozhou bay is 10 to 15m. The channel is 45m deep between Calais and Dover (the shortest and shallowest crossing). Moreover the strait of Dover (or Pas de Calais in french) is the busiest shipping lane in the world http://i.dailymail.co.uk/i/pix/2014/05/22/article-2636152-1E1A483000000578-594_964x516.jpg http://i.dailymail.co.uk/i/pix/2014/05/22/article-2636152-1E...
