The groundbreaking Shantou Bay Undersea Tunnel, the world's first dual-track high-speed railway tunnel capable of speeds up to 350 km/h and spanning a total length of 9,781 meters, has been successfully completed. This monumental achievement marks a significant milestone in the construction of the Shantou-Shantou High-speed Railway. Despite the formidable challenges posed by complex geology, the tunnel has emerged as a paragon of innovation, setting new benchmarks in pressure resistance, earthquake resilience, and corrosion protection. The Shantou-Shantou High-speed Railway is anticipated to commence operations by the end of this year, seamlessly integrating with multiple high-speed rail networks to forge a high-speed rail corridor along China's southeast coast, thereby driving high-quality development in the eastern coastal regions.
