strait of gibraltar bridge

These claims are to be found in chapter 14 of Vol II of The American Nations published in 1836. [19] Archaeological evidence of Homo sapiens habitation of the area dates back c. 40,000 years.

Retrieved 3 February 2009. In a rare 1935 book, Accion de España en Africa(a)  (Spanish Action in Africa) he refers to the ancient isthmus that linked Spain and North Africa as well as landbridges linking Europe and America on which he believed Atlantis had been situated. In December 2003, Spain and Morocco agreed to explore the construction of an undersea rail tunnel to connect their rail systems across the Strait. Look at the recent UK Acton Swing bridge repair using light weight concrete. Through the Strait, water generally flows more or less continually in both an eastward and a westward direction. Lin's proposal for a crossing between Point Oliveros and Point Cires featured deep piers, a length of 14 kilometres (9 miles), 910-metre-tall (3,000 ft) towers, and a 5,000-metre (16,000-foot) span, more than twice the length of the current longest bridge span. The two continents are separated by 13 kilometres (8.1 miles; 7.0 nautical miles) of ocean at the Strait's narrowest point between Point Marroquí in Spain and Point Cires in Morocco. Other researchers such as Constantin Benetatos maintain that this idea is supported by comments of ancient writers who suggest that at one time the Mediterranean had no existence. The standard argument against the landbridge theory is that although the Atlantic was dramatically lower during the last Ice Age it was not sufficient to expose a land bridge between Spain and Africa at Gibraltar. Around 5.9 million years ago,[14] the connection between the Mediterranean Sea and the Atlantic Ocean along the Betic and Rifan Corridor was progressively restricted until its total closure, effectively causing the salinity of the Mediterranean to rise periodically within the gypsum and salt deposition range, during what is known as the Messinian salinity crisis. In the Middle Ages, Muslims called it Az-Zuqāq (الزقاق), "the Passage", the Romans called it Fretum Gaditanum (Strait of Cadiz),[9] and in the ancient world it was known as the "Pillars of Hercules" (Ancient Greek: αἱ Ἡράκλειοι στῆλαι, romanized: hai Hērákleioi stêlai).[10]. For comparison, the currently deepest undersea tunnel, the Norwegian Ryfylke Tunnel, is 291 metres (955 ft) below sea level. They are not necessarily suggesting that they build a bridge, actually across the Strait of Gibraltar, they were merely suggesting that a bridge design would be capable of carrying loads across a distance that long.

[15] [12], In December 2003, Spain and Morocco agreed[13][14] to explore the construction of an underwater rail tunnel to connect their rail systems. [11], The International Hydrographic Organization defines the limits of the Strait of Gibraltar as follows:[12]. "Website of the project of the fixed link through the Strait of Gibraltar". The relatively short distance between the two shores has served as a quick crossing point for various groups and civilizations throughout history, including Carthaginians campaigning against Rome, Romans travelling between the provinces of Hispania and Mauritania, Vandals raiding south from Germania through Western Rome and into North Africa in the 5th century, Moors and Berbers in the 8th–11th centuries, and Spain and Portugal in the 16th century. The presence of two deep Quaternary clay channels in the middle of the Strait makes construction complex,[8] causing doubts about the feasibility of the project and proposals for an exploratory tunnel. This enclave was first established in 1704 and has since been used by Britain to act as a surety for control of the sea lanes into and out of the Mediterranean.

A major problem arose when the engineers hired by the Spanish government discovered that the material under the Strait was extremely hard rock, making tunnelling impossible with the available technology.

The Millau Bridge has a total length of 8,071ft with the longest single span at 1,122ft and a maximum clearance below of 886ft; in short the bridge is massively impressive both on paper and in real life.

If construction ever begins it will be the biggest architectural project in the world. [5][clarification needed], Various tunnels have been proposed. A report[8][9][10] on the feasibility of the tunnel was presented to the EU in 2009. The Strait depth extends to 900 metres (3,000 ft) on the shortest route, although it is only about 300 metres deep slightly further west, where the European and African tectonic plates meet. It was just a theoretical example of the kind of distance the bridge could effectively cross if required someone in the world. [11] One consequence of the declaration was the creation in 1981 (39 years ago) (1981) of SECEGSA, the Spanish government-funded corporation whose job is to "study" and "promote" the crossing.

Even though the waves may occur down to great depths, occasionally the waves are almost imperceptible at the surface, at other times they can be seen clearly in satellite imagery. When the Mediterranean eventually filled up, it is highly probable that it was then that the pressure of its waters led to the flooding of the Black Sea. [3], In 2004, architect Eugene Tsui published his concept for a floating and submerged bridge, connected at a three-mile wide island in the middle of the Mediterranean Sea. It depends, The shortest distance between the Spanish coast and the Moroccan coast is 14 kms (9 miles) but its maximum depth is 900 meters below sea level. [16] According to the company, the main differences between the construction of this tunnel and that of the Channel Tunnel, linking France and Great Britain, are the depth of the sea and the geological conditions. Each month, we’ll bring you hundreds of the latest roles from across the industry. (Source: Javno), Bering Strait Bridge: The 55 mile long bridge across the Bering Strait would connect Asia and North America for the first time since the continents touched each other. Back to the Dam idea! When we consider that the breaching of a landbridge at Gibraltar would have caused an incredible flow of water through the breach (hundreds of times the flow of Niagara Falls), scouring its bottom, so that by the time the levels in the Atlantic and the Mediterranean had equalised, the erosion of the sill between them would have been considerable and when viewed today would misleadingly suggest that the Mediterranean had not have been completely cut off from the Atlantic during the last Ice Age. Registered in England No. It is believed that this process took a short time, by geological standards, lasting between 500,000 and 600,000 years. However, it should be noted that the underwater sill between the Atlantic and the Mediterranean would have been much higher than now. The Strait of Gibraltar is already ably served by ferries and boats chugging from Algeciras (in Spain) to Tangier Med (in Morocco). 2012. [27] There are several islets, such as the disputed Isla Perejil, that are claimed by both Morocco and Spain. On the northern side of the Strait are Spain and Gibraltar (a British overseas territory in the Iberian Peninsula), while on the southern side are Morocco and Ceuta (a Spanish autonomous city in northern Africa). After years of discussion and planning, eventually in October 2007 the Indonesian government gave the initial go-ahead for what will become the world’s longest suspension bridge, across the 26km (16mi) Sunda Strait. With its 14km length, deep piers, and unprecedented 5000 meter spans Lin’s proposed crossing is innovative but, considering an estimated cost of over 15 Billion dollars and the lack of approval for this nearly 10 year old design, we doubt it will ever be built. The United Kingdom claims 3 nautical miles (5.6 km; 3.5 mi) around Gibraltar on the northern side of the Strait, putting part of it inside British territorial waters.

[5] Ferries cross between the two continents every day in as little as 35 minutes. The Strait of Gibraltar was formed by two meteor impacts. One well-illustrated website(h) attributes this rupture to a meteor impact! “Very often there are slight variations on [the mathematically optimal] forms, which are only very slightly less efficient, in that there is very little extra weight, but they are much easier to build,” said Gilbert. The Spanish researcher Paulino Zamarro contends, in his 2000 book, Del Estrecho de Gibraltar a la Atlantida that a Gibraltar dam was created by silting when the Atlantic was very much lower during the last Ice Age and that it lasted until 7,500 years ago when it was breached and destroyed Atlantis, which he locates in the Cyclades, with the island of Melos containing its capital city. The Strait of Gibraltar crossing is a hypothetical bridge or tunnel spanning the Strait of Gibraltar (about 14 km or 9 miles at its narrowest point) that would connect Europe and Africa. [2], Several engineers have designed bridges on various alignments and with differing structural configurations. It is worth considering that although the catastrophic breaching of the Bosporus and consequent expansion of the Black Sea is generally accepted as fact, there are no specific legends to support it apart from a reappraisal of the Flood of Noah. Professor T.Y. One example, Euroroute (pictured above), would literally take drivers through the White Cliffs of Dover to an island five miles into the English Channel where a tunnel would bring drivers the twenty remaining miles to France. The Betic Corridor in the north, which later became part of the Spanish Guadalquivir Basin and the Rifian Corridor in the south, in what is now Morocco. I have addressed the critical questions of when, where and who, using Plato’s own words, tempered with some critical thinking and a modicum of common sense. This design is different.
