Xiang'an Tunnel, the first domestically developed undersea tunnel in the Chinese mainland, opened on April 26, 2010. It has the world's largest undersea section.

Many Chinese central state-owned enterprises, such as China Railway Group Limited and China Railway Construction Corporation Limited, participated in the tunnel's construction.

The passage was completely developed domestically, from design to construction, which was a milestone for China.

The tunnel has the highest level of corrosion resistance and waterproof performance and can withstand a magnitude-8 earthquake.
