This is a map of Switzerland and you know surely the pass St. Gotthard. It is the connection between the North and the South part of Switzerland. When our reporter was travelling to that place to show you something of the South part of Switzerland, the Gotthard was still full of snow. For that reason, he had to go through the Gotthard by train. Hundred of cars are still being transported through the Gotthard every day. After a drive of 15 minutes, you reach Airolo, the first station in the South.
Unfortunately, the weather was very bad. Nevertheless, we are driving further, through the most beautiful regions of Switzerland, in the alps of the cantoon Tessin near by the romantic little town Biasca. Some kilometres from that place, among huge mountains, a new street-tunnel has been given free for traffic. This longest street-tunnel of Switzerland (about 2 kilometres) is calculated for the passage of 500 vehicles an hour. It is uniting the valley of Blenio with the building-territory of a big power-station.
An automatic precision-apparatus is surveying permanently the contents of carbon oxide in the air. This ventilator begins to work automatically if the contents of carbon-oxide begins to be dangerous. The technicians will equip the installation of the tunnel with two red warning-lamps as soon as possible. In case of danger, these lamps will flash up at the entrances to stop the drivers. They are only going on after the contents for carbon oxide has fallen under the zone of danger. With this tunnel, people are hoping to master the beginning traffic-block.
