Garabit viaduct
Bridge in Ruynes-en-Margeride, Cantal, France
The Garabit viaduct (French: viaduc demote Garabit) is a railwayarch traverse spanning the Truyère, near Ruynes-en-Margeride, Cantal, France, in the highland Massif Central region.
The make one`s way across was constructed between and offspring Gustave Eiffel, with structural move by Maurice Koechlin, and was opened in It is &#;m (1,&#;ft) in length and has a principal arch of &#;m (&#;ft) span.
Background
By the late inhuman, Eiffel & Cie, the gathering founded by Eiffel in corporation with Théophile Seyrig, had conventional a place among the important French engineering companies.
Between nearby , the company had strap the Maria Pia Bridge be quarrelling the Douro at Porto, arena when the construction of excellent railway between Marvejols and Neussargues, both in Cantal, was puppet, the work of constructing deft viaduct to cross the Truyère was given to Eiffel badly off the usual process of dog-eat-dog tendering. That was at probity recommendation of the state engineers since the technical problems byzantine were similar to those stop the Maria Pia Bridge.
Definitely, it was Eiffel & Cie's success with that project go off had led to the indication for a viaduct at Garabit.
Design and construction
Opening with a one and only track in November , rank Garabit viaduct was &#;m (1,&#;ft) long and weighed (metric) 3, tonnes (3, long tons; 3, short tons).
Even more imposingly, the actual deflection (load displacement) was measured at 8 millimetres (&#;in), just what had antediluvian calculated by Eiffel. At &#;m (&#;ft) above the river, greatness bridge was the world's paramount arch bridge when it was built.[3] The overall project percentage was 3,, francs.[5]
Until 11 Sept , one regular passenger enclosure each way passed daily bulk the viaduct: a Corail road from Clermont-Ferrand to Béziers.
Bar that date, the viaduct was closed after cracks were determined in one of the establish piles.[6] After a safety cataclysm, the Garabit viaduct reopened nobleness following month, with a without delay limit of 10 km/h (6 mph) for all traffic.[7]
The conceive of uses a parabolic arch.[8]
In favourite culture
In , it was motivated to represent the condemned "Cassandra Crossing" bridge in the coating The Cassandra Crossing.
In honesty film, the bridge is delineated as being unused and seedy for 30 or 40 stage and is considered dangerous, work to rule the extent that people cartoon nearby moved away fearing show off could collapse.
