Long Biên Bridge (Vietnamese: C?u Long Biên) is a historic cantilever bridge across the Red River that connects two districts, Hoan Kiem and Long Bien of the city of Hanoi, Vietnam. It was originally called Paul Doumer Bridge.
The bridge was built in 1899-1902 by the architects Daydé & Pillé of Paris, and opened in 1903. Before North Vietnam's independence in 1954, it was called Paul-Doumer Bridge, named after Paul Doumer - The Governor-General of French Indochina and then French president. At 2.4 kilometres (1.5 mi) in length, it was, at that time, one of the longest bridges in Asia. For the French colonial government, the construction was of strategic importance in securing control of northern Vietnam. From 1899 to 1902, more than 3,000 Vietnamese took part in the construction.
It was heavily bombarded during Vietnam War due to its critical position (the only bridge at that time across the Red River connecting Hanoi to the main port of Haiphong). The first attack took place in 1967, and the center span of the bridge was felled by an attack by 20 USAF F-105 fighter-bombers. CIA reports noted that the severing of the bridge did not appear to have caused as much disruption as had been expected. The defence of Long Bien Bridge continues to play a large role in Hanoi's self-image and is often extolled in poetry and song. It was rendered unusable for a year when, in May 1972, it fell victim to one of the first co-ordinated attacks using laser-guided "smart bombs".
Some parts of the original structure remain intact, while large sections have been built later to repair the holes. Only half of the bridge retains its original shape. A project with support and loan from the French government is currently in progress to restore the bridge to its original appearance.
Today trains, mopeds, bicycles and pedestrians use the dilapidated bridge, while all other traffic is diverted to the nearby Chng Dng Bridge and some newly built bridges: Thanh Trì Bridge, Th?ng Long Bridge, V?nh Tuy Bridge, and Nh?t Tân Bridge.
Under the bridge, poor families live in boats on the Red River, coming from many rural areas of Vietnam.
