With its concrete and steel pillars soaring high above the morning fog in the Tarn Valley, the construction makes a spectacular sight." <a href="http://news.bbc.co.uk/2/hi/europe/4091813.stm" target="_blank">(source)</a> <img src="http://lh5.google.ca/abramsv/R4u4aUKUmoI/AAAAAAAADZ4/oyYIdeam6vU/s720/398591267_d012e7fa2a_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Construction began in October 2001 and was intended to take three years, but dragged even longer because of weather conditions. The bridge was built by         Eiffage, the same company that built the Eiffel Tower. <img src="http://lh4.google.ca/abramsv/R4u4rEKUmpI/AAAAAAAADaA/5PcTLSebWP8/s720/391932949_75c7fe9773_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u4wkKUmqI/AAAAAAAADaI/CbH0PhUwa9Y/s720/391932970_2d9fb6e9da_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh4.google.ca/abramsv/R4u47EKUmrI/AAAAAAAADaQ/c6sN63BHm7E/s720/391932988_2e94a868fe_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh5.google.ca/abramsv/R4u5BUKUmsI/AAAAAAAADaY/-A7tJlr6IkA/s720/391932999_4d6b9f3564_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u5JkKUmtI/AAAAAAAADag/WXLdWBtPb1E/s720/398591242_c0218d99e9_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4vB8kKUm-I/AAAAAAAADcs/RT7r9iixfl0/s720/391933056_88f8d5fd50_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh3.google.ca/abramsv/R4u5P0KUmuI/AAAAAAAADao/mUU6J8V2OEI/s720/398615933_4264a121f5_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh3.google.ca/abramsv/R4u6O0KUmwI/AAAAAAAADa4/LFROPxkzrS4/s720/398615935_a2d5270656_o-2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Towers rise from the clouds: <img src="http://lh3.google.ca/abramsv/R4u6G0KUmvI/AAAAAAAADaw/-2dQaYhHZKg/s720/398597934_0e8b543c7a_o-2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u6VkKUmxI/AAAAAAAADbA/FlHlCu-t1zc/s720/398598141_30e3e07946_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u6ckKUmyI/AAAAAAAADbM/Nk_hoyJznQE/s720/398598038_18efdb3ffa_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u6jkKUmzI/AAAAAAAADbU/jkM0Edg7wTc/s720/398597959_9f2ed17859_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> A complicated system of hydraulic rams was used to slide the vast bridge deck into place. It was provided by Enerpac Hydraulic Systems - the company which also "lifted" Golden Gate Bridge off its foundation for better cushioning against earthquakes. Here is a diagram of                   pushing the bridge's deck: <img src="http://lh5.google.ca/abramsv/R4u60UKUm0I/AAAAAAAADbc/ly0Y3v00S2g/s720/398591300_85907c72b3_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u67kKUm1I/AAAAAAAADbk/M-sp6rk_pT0/s720/398591336_75983d3ca3_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> "The deck was pushed in two sections from both sides of the valley. Each push cycle lasted 4 minutes and moved the deck section 600mm a time." <img src="http://lh5.google.ca/abramsv/R4vCLUKUm_I/AAAAAAAADc0/zXgZjVREnt4/s800/391933075_0e680ba4a3_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh4.google.ca/abramsv/R4u7EEKUm2I/AAAAAAAADbs/pBwLztf3NSA/s720/398591204_df13348cf7_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh5.google.ca/abramsv/R4u7KUKUm3I/AAAAAAAADb0/HgV0J2ILsOw/s720/398602879_cceafdee2f_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh5.google.ca/abramsv/R4u7RUKUm4I/AAAAAAAADb8/Oh2RJ_mKChI/s720/398598183_78c9ad7160_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Enduring materials and unique cable design: <img src="http://lh6.google.ca/abramsv/R4u7XkKUm5I/AAAAAAAADcE/SWPuvHlzGP8/s720/391933117_47c2d92471_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh6.google.ca/abramsv/R4u7dkKUm6I/AAAAAAAADcM/-cx97QDE6e8/s720/391933131_ad5a9753c7_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://lh4.google.ca/abramsv/R4u7tEKUm7I/AAAAAAAADcU/uVi_QzJKTl4/s720/391933149_e31fa63f14_o-1.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> From both sides of the valley the metal sections of the bridge are assembled, lifted slightly and then in an elaborate manoeuvre pushed into place on each of the seven supporting pillars. The architect, Norman Foster, said the bridge was designed to have the "delicacy of a butterfly" <img src="http://lh5.google.ca/abramsv/R4u71UKUm8I/AAAAAAAADcc/f5dm2k8xm9E/s720/398598077_4b75d74d30_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> </blockquote>
