When will the Qiongzhou Strait Cross-Harbour Tunnel be built? When will it be completed?

The Qiongzhou Strait Cross-Harbour Tunnel was opened in 212; As of July 221, the Qiongzhou Strait Cross-Harbour Tunnel has been completed;

connecting Leizhou Peninsula and Hainan Island, connecting Beibu Gulf in the west and northern South China Sea in the east, it is a cross-sea passage with dual purposes of road and railway. Qiongzhou Strait is about 8 kilometers long from east to west, with an average width of 29.5 kilometers from north to south, with a straight line distance of 33.5 kilometers at its widest point and 18 kilometers at its narrowest point. The total investment of the channel exceeds 15 billion yuan.

in p>1974, premier Zhou Enlai instructed Wan Li, vice premier of the State Council, to organize research on the construction of the Qiongzhou strait submarine railway tunnel. "This is the first time that the first generation of leaders of the People's Republic of China explicitly proposed to build a cross-sea passage and a cross-sea railway in the Qiongzhou Strait." ?

project introduction

Qiongzhou Strait, located between Leizhou Peninsula and Hainan Island, is one of the three major straits in China. It is about 8 kilometers long from east to west, with an average width of 29.5 kilometers from north to south and a straight line distance of about 18 kilometers at its narrowest point. Qiongzhou Strait has hindered the land transportation between Hainan Island and the mainland, and directly affected the economic development of Hainan. It is urgent to build a cross-sea channel in Qiongzhou Strait.

Since the 199s, China's Ministry of Communications, Ministry of Railways and Guangdong Province have carried out project research on Qiongzhou Strait Cross-sea Passage respectively. In 28, under the guidance and coordination of the National Development and Reform Commission, the Ministry of Railways, the Ministry of Transport, Guangdong Province and Hainan Province jointly planned the project. China Railway Bridge Survey and Design Institute, which has participated in the design of cross-sea projects such as Donghai Bridge and Hangzhou Bay Bridge, is responsible for the preliminary research of this project.
