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:
“There is a constant in the average American imagination and taste, for which the past must be preserved and celebrated in full-scale authentic copy; a philosophy of immortality as duplication. It dominates the relation with the self, with the past, not infrequently with the present, always with History and, even, with the European tradition.”
—Umberto Eco (b. 1932)
“The history of reform is always identical; it is the comparison of the idea with the fact. Our modes of living are not agreeable to our imagination. We suspect they are unworthy. We arraign our daily employments.”
—Ralph Waldo Emerson (1803–1882)
“Don’t give your opinions about Art and the Purpose of Life. They are of little interest and, anyway, you can’t express them. Don’t analyse yourself. Give the relevant facts and let your readers make their own judgments. Stick to your story. It is not the most important subject in history but it is one about which you are uniquely qualified to speak.”
—Evelyn Waugh (1903–1966)
