Plan to build world's longest undersea tunnel from Dalian to Yantai
The proposed 123-kilometre railway project would carry passengers and vehicles between the port cities of Dalian in Liaoning's and Yantai in Shandong , according to Time Weekly, a Guangdong-based newspaper.
The government is planning to spend 260 billion yuan (HK$326 billion) to build the world's longest undersea tunnel across the Bohai Strait.
The report said the tunnel, of which 90 kilometres would be under water, would surpass the world's two longest channel tunnels - Japan's Seikan Tunnel and the Channel Tunnel that connects Britain and France.
"It is a key national project that won the full support of Premier Li Keqiang when he was Liaoning's party chief in 2004," said Professor Wang Mengshu , a tunnel and railways expert from the Chinese Academy of Engineering.
Wang said the Bohai Sea tunnel was a critical part of the country's 5,700-kilometre railway project to link the cities of Tongshan in the northeast and Sanya in Hainan .
