Because the railroad which bound マルヴジョル and ヌサルグ = モワサック together in a certain railway bridge near Cantal, France, Rue dog = ザン = マルジュリド (Ruynes) went over the トリュイエール river which was the branch of the lot river which drifted to the Central Highlands, the Gullah bibridge (Buddha: Le Viaduc de Garabit: a Gullah biviaduct) was built. The company performed the construction with ギュスターヴ Eiffel and was completed in 1884. It was 1888 that a railroad was inaugurated.

A Gullah bibridge is a bridge of 564.85m in length supported in a supporting beam made of seven wrought irons. The supporting beam has an altitude of 80 meters with the highest thing. As for 3 trave more than the lowest places of the gorge, a span is supported by 165m, a single arch of 52m in height. And a brick viaduct of 46m and 71m continues to sandwich this part from the north and south. The height from shortage of water rank of the トリュイエール river was 122.5m, but, as for the height from the surface of the water, it is 95m because a dam is built in 1959 by the トリュイエール river, and there was a dam lake for 28km in length.
A plan was entrusted to young engineer Leon ボワイエ. He took down a track by the old method every valley and built a bridge over the branch of the トリュイエール river and went one by one, but he adopted a plan to go over a plateau and the valley directly at a viaduct and a huge bridge.
I was not able to build a suspension bridge. This is because it was not able to build the main tower which is more expensive than 65m in a problem and this time of the vibration. Therefore I took the form same as the Maria Pia Bridge who hung in the Portuguese ドウロ river. This bridge was an arched bridge of 160m between central diameters built by Eiffel and Theo Phil say rig, Eiffel Corporation.
