Major cities and most of the population are located in the south shore of the Yangtze River and the deep sea port such as NanTong is located in the north.

There are many challenges to build bridges across the mouth of Yangtze river.

- The river gets wider, deeper (30m for one of the main Pier)

- Since the shipping traffic is extremely heavy with ocean liner, the bridge span and height require is very high.

- The soft silty sand and clay settlement is very thick above the rock bed.

- The bridge not only have to withstand the worst downstream flow which is one of the heaviest in the world but also annual upstream salt water oceanic tide (silver serpent) which can be as bad as a Tsunami.

This is one of the many Bridges and tunnel build across this river in the last five or ten years which will shorten travel time by 75% and promote faster growth on the north shore. Why now? Because they can now overcome the technical challenge, to balance growth in different region and the fast economic growth required more efficient mode of transportation and provided required funding of such major project.
