Sonnenberg Tunnel
The Sonnenberg Tunnel is a long motorway tunnel, constructed between 1971 and 1976 and located in Lucerne, Switzerland. At its completion it was also the world's largest civilian nuclear fallout shelter, designed to protect 20,000 civilians in the eventuality of war or disaster. Catherine Frammery"Dans les entrailles du Sonnenberg, monstrueux témoin de la Guerre froide" ''Le temps'', Monday 15 August 2016 (page visited on 15 August 2015). Motorway tunnel The A2 motorway from Chiasso to Basel passes through the tunnel and carries around 55,000 vehicles a day. There are tentative plans to construct a bypass to replace the section of the motorway that leads through Lucerne, which includes the Sonnenberg and Reussport tunnels. Civil defense shelter Based on a federal law from 1963, Switzerland aims to provide nuclear fallout shelters for the entire population of the country. The construction of a new tunnel near an urban centre was seen as an opportunity to provide shelter spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiasso
Chiasso (; lmo, Ciass ) is a municipality in the district of Mendrisio in the canton of Ticino in Switzerland. As the southernmost of Switzerland's municipalities, Chiasso is on the border with Italy, in front of Ponte Chiasso (a frazione of Como, Italy). The municipality of Chiasso includes the villages of Boffalora, Pedrinate and Seseglio. In 2007, the three mayors of Chiasso, Vacallo and Morbio Inferiore decided to unite into one commune. The new united commune with a population of ~15,300 people over a territory of , was rejected by the population in November 2007. History Chiasso is first mentioned in 1140 as ''Claso''. Chiasso (and Boffalora) Historically, Chiasso and Boffalora were two distinct agricultural villages. Due to the nearby Italian border and customs office, and later as part of an access route to the St. Gotthard's Tunnel, the two villages merged and grew. Chiasso's history and development were strongly influenced by its unique location. In its early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Tunnels In Switzerland
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Tunnels Completed In 1976
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A Pipeline transport, pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossi ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...

TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A2 Motorway (Switzerland)
The A2 (the Gotthard Motorway) is a motorway in Switzerland. It forms Switzerland's main north–south axis from Basel to Chiasso, meandering with a slight drift toward the east. It lies on the Gotthard axis and crosses the Alps. Opened in 1955 under the name "Road Lucerne-south", A2 is one of the busiest motorways in Switzerland. The A2 motorway leaves Basel heading south toward Olten, Sursee, Luzern, Stans, Altdorf, Erstfeld, Göschenen, Airolo, Biasca, Bellinzona, Lugano and reaches Chiasso. It intersects with the A1, A8, A13 and A14 motorways. The St. Gotthard Tunnel lies at the heart of the motorway and makes up its culminating point. With a maximum elevation of at the tunnel's highest point, the A2 motorway has the lowest maximum elevation of any direct north–south road through the Alps. Traffic jams stretching for kilometres on end are frequently found on both entrances of the tunnel, but more frequently on the northern flank. The difficulty with driving through ...

Motorway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include '' throughway'' and '' parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arteri ...
