From Dream to Reality after Nearly 70 Years
Swiss engineer Karl Edward Lattice Lv Na put forward construction of railway tunnel vision across the Alps in 1947. He had expected that the tunnel would be built in the early 21st century.
In 1963, the Swiss government set up a committee to study tunnel construction plans, but there were different kinds of solutions. In the end, the Swiss government thought that it is not a priority to build the railway tunnel in 1983, and plans were shelved.
There was a referendum in 1992 in Switzerland, as a result, most people supported to build a tunnel. However, the building plan was put off again due to cost.
In November 1998, there was a referendum once again and finally the project was started.
In order to save time, the project was divided into five period of construction at the same time, the peak more than 2000 workers working at the same time. The eastern and western tunnel respectively connected in October 2010 and March 2011.
The whole project cost about 12 billion Swiss francs (about 79.2 billion yuan).
