Pont Doumer
The bridge Paul-Doumer is with Hanoi and makes it possible the railway to cross the Red Fleuve towards Lao Cai for then moving towards the Yunnan.
It was built at the time of the French Indo-China by the company Daydé & Pillé, surviving company since by the Eiffel group and was finished in 1903.
The general governor of Indo-China, Paul Doumer, large promoter of the rail-bound transports, had left him his name. With independence, the bridge was famous the bridge Long Good. Hanoïens remain, however, very attached there.
The speed of this construction is to be associated with the geographical distance of France and the weakness of the local iron and steel industry of the time. It was thus a true technological prowess.
It belongs to the very many metal structures which have built in the style Eiffel, that one also finds in Dalat.
It is a bridge of the type to cantilever beams an overall length of 1680m
It is probably the large bridge more rafistolé of the world. A certain lack of maintenance and especially the intense bombardments which it underwent on behalf of the United States at the time of the war of Vietnam, if they never could destroy it definitively, seriously put at evil its structure [http://www.patrimsf.org/French/pdf/Hanoi.pdf]. Piles, in particular, were added to consolidate it.
