Long Bien Bridge was constructed by the French in the 19th century. Construction on the 1,682-metre long bridge started in 1899 and was finished in 1902. It was expanded in 1924 to serve motorised transport.
Long Bien Bridge was hit 14 times by bombs with many piers and seven spans heavily damaged by US airstrikes in 1965 and 1972. The bridge was then restored and mended but its original design was preserved.
In the early 1980s, Chuong Duong Bridge was built next to the Long Bien Bridge to serve the increased traffic volumes in the capital city.
The two bridges connect the two inner districts of Hoan Kiem and Long Bien.
Chuong Duong Bridge is 1,210 metres long and made from steel.
Thang Long Bridge was constructed in 1985 with the support of the Soviet Union and was among the largest bridge projects in South East Asia at that time.
