title: Channel Tunnel text: the top tunnel used for transport and the bottom one for groundwater flows. In 1839, Aimé Thomé de Gamond, a Frenchman, performed the first geological and hydrographical surveys on the Channel, between Calais and Dover. Thomé de Gamond explored several schemes and, in 1856, he presented a proposal to Napoleon III for a mined railway tunnel from Cap Gris-Nez to Eastwater Point with a port/airshaft on the Varne sandbank at a cost of 170 million francs, or less than £7 million. In 1865, a deputation led by George Ward Hunt proposed the idea of a tunnel to the Chancellor of title: Channel Tunnel text: The project was abandoned in May 1882, owing to British political and press campaigns asserting that a tunnel would compromise Britain's national defences. These early works were encountered more than a century later during the TML project. A 1907 film, "Tunnelling the English Channel" by pioneer filmmaker Georges Méliès, depicts King Edward VII and President Armand Fallières dreaming of building a tunnel under the English Channel. In 1919, during the Paris Peace Conference, the British prime minister, David Lloyd George, repeatedly brought up the idea of a Channel tunnel as a way of reassuring France about British willingness to defend title: Channel Tunnel text: for a cross-Channel fixed link appeared as early as 1802, but British political and press pressure over the compromising of national security stalled attempts to construct a tunnel. An early attempt at building a Channel Tunnel was made in the late 19th century, on the English side, "in the hope of forcing the hand of the English Government". The eventual successful project, organised by Eurotunnel, began construction in 1988 and opened in 1994. At £5.5 billion (1985 prices), it was at the time the most expensive construction project ever proposed. The cost finally amounted to £9 billion ($21 billion), well title: Channel Tunnel text: Tunnel?" There was another proposal in 1929, but nothing came of this discussion and the idea was shelved. Proponents estimated construction to be about US$150 million. The engineers had addressed the concerns of both nations' military leaders by designing two sumps—one near the coast of each country—that could be flooded at will to block the tunnel. This design feature did not override the concerns of both nations' military leaders, and other concerns about hordes of undesirable tourists who would disrupt English habits of living. Military fears continued during the Second World War. After the fall of France, as Britain prepared title: Channel Tunnel text: a privately funded project. In 1981 Thatcher and François Mitterrand, the French president, agreed to establish a working group to evaluate a privately funded project. In June 1982 the Franco-British study group favoured a twin tunnel to accommodate conventional trains and a vehicle shuttle service. In April 1985 promoters were invited to submit scheme proposals. Four submissions were shortlisted: The cross-Channel ferry industry protested under the name "Flexilink". In 1975 there was no campaign protesting against a fixed link, with one of the largest ferry operators (Sealink) being state-owned. Flexilink continued rousing opposition throughout 1986 and 1987. Public opinion strongly
