The Gotthard Tunnel in Switzerland runs from Göschenen in the Canton of Uri at its northern portal, to Airolo in Ticino to the south, and is in length below the Gotthard Pass. It is the fourth-longest road tunnel in the world after Norway's Lærdal Tunnel (24.5 km), Japan's Yamate Tunnel, and China's Zhongnanshan Tunnel (18 km). == History == In response to the automobile boom in Switzerland and other things, the Swiss government gave approval in July 1969 for the construction of the 16-kilometre Gotthard Road tunnel. The tunnel would be longer than any existing road tunnel, and would provide a year-round road link between central Switzerland and Milan to be used in place of the Gotthard Pass. The now widely used motorway tunnel was opened on 5 September 1980. It remains a single bore tunnel with just one lane operating in each direction. It has four large ventilation shafts and an additional side gallery between 10 and 18 metres from the main tunnel, having its own independent ventilation system in order to facilitate the cutting of a second tunnel, should future traffic levels require it.〔 In March 2014, the Swiss Government approved a bill that will allow the building of a second road tunnel. The building is scheduled to start in 2020, with the cost estimated at almost $3 billion.〔http://www.swissinfo.ch/eng/emotional-debate_second-gotthard-road-tunnel-given-green-light/40797948〕 There is no reference to a toll.
