History
In response to the automobile boom in Switzerland and the popularity of Italy as a travel resort, 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 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 September 5, 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.
On Friday, October 24, 2001, a collision of two trucks created a fire in the tunnel, killing eleven and injuring many more, the smoke and gases produced by the fires being the main cause of death. The effects of even small fires in a confined space like a tunnel are extremely serious because of the inability of gases and heat to disperse. For instance, carbon monoxide is highly toxic at very low concentrations; having this trapped in a confined space allows concentrations to build well beyond a fatal level. The tunnel was closed for two months after the accident for repair and cleaning.

Famous quotes containing the word history:
“Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the “anticipation of Nature.””
—Thomas Henry Huxley (1825–95)
“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
“In nature, all is useful, all is beautiful. It is therefore beautiful, because it is alive, moving, reproductive; it is therefore useful, because it is symmetrical and fair. Beauty will not come at the call of a legislature, nor will it repeat in England or America its history in Greece. It will come, as always, unannounced, and spring up between the feet of brave and earnest men.”
—Ralph Waldo Emerson (1803–1882)
