The Ministry of Transport also asked Hanoi Municipal People's Committee to prepare a dossier to recognise the bridge, according to regulations.
Designed by the French architect, Alexandre Gustave Eiffel, the 2,290m Long Bien Bridge was built between 1897 and 1902 and opened to traffic in 1903.
As the only bridge across the Red River that connected Hanoi to the highway leading to the northern port city of Hai Phong, the bridge played a crucial role in many important events in the country's history, including the independence wars.
The bridge was initially called the Doumer Bridge. At the time of construction, it was one of the world's longest bridges and one of the most important engineering works of the Far East.
It was built by contractor Daydé & Pillé, under the leadership of the Indochina Governor Paul Doumer.
After the country’s liberation, the bridge was renamed Long Bien.
For over 100 years, it witnessing many changes and from the country's wartime to peacetime, Long Bien Bridge has become a symbol of the history of Vietnam.
