1. Long Bien Bridge, also known as Cau Long Bien, is a historic cantilever bridge spanning the Red River in Hanoi, Vietnam. The bridge was designed by engineer Gustave Eiffel and was completed in 1902. It is one of the oldest bridges in Vietnam and has become an iconic symbol of Hanoi. The bridge has five iron spans, with a total length of 1,682m, and was once the longest bridge in Indochina. During the Vietnam War, the bridge was bombed several times by American military, but it was always repaired and remained in use. Today, it serves as an important transportation route and also attracts tourists who come to admire its architectural beauty and historical significance.

3. The most common way to get to Long Bien Bridge is by taking a taxi or motorbike from the city center. You can also take bus #31 or #33 from Hanoi Old Quarter to Long Bien Bus Station, which is located near the bridge. From there, it’s a short walk to the bridge entrance.
