Why hasn’t the bridge connecting Hainan been built after a hundred years of hesitation?

The Qiongzhou Strait bridge connecting mainland China and Hainan Island, a hot topic especially during the 2024 Spring festival due to travel congestion, has remained unbuilt for nearly a hundred years, despite its distance of only 20km. Major issues include complex geological conditions like frequent earthquakes, strong winds, and high waves, and an average strait depth of 44 meters, requiring bridge piers as tall as a 30-storey building. While an undersea tunnel is an option, it presents its own set of challenges including difficult exit ramps, sesimic activity, and high costs. The bridge's absence raises questions not just on the technical and economic aspects, but also touches upon historical and cultural considerations.

Interesting discourse on the problems facing this attempt to build a bridge that seems impractical both economically and safety wise, but it was worth the study to reach that conclusion. Maybe one day there will be newer technology to create an undersea tube with enough elasticity to survive an 9 level earthquake. Dreams never cease and technology might one day make dreams a reality.

Hainan Island is a beautiful place, if you build a bridge and 100000 cars show up where will they park, that means they will have to cut down so much green space , People go there for the beaches and laid back relaxing scenery, Whos wants to visit a parking lot and another city,

Because of insignificant economic benefits vs cost of construction and there’s no political pressure. Most likely the construction of connecting to Taiwan will be accomplished first. The experience and knowledge acquired from that project will enable the commitment to finally connecting Hainan to mainland.

There are at least three technologies that could be used to overcome the obstacles if sea bridge is chosen .. First harness the strong wind with wind farm , second use wave harvesting technology to harvest wave energy and third use oil rig anchoring to bridge the 144 meters valley . In addition use earthquake absorbtion technology to preserve the bridge liespan. I think with these technologies the cost of building the seabridge will be much lower than 100 billion or lower .

Undersea bridge more practical
