The Thăng Long Bridge (Cầu Thăng Long, completed 1978) is a two-level crossing over the Red River in northern Hanoi. It forms a key segment of Ringway 3 of Hanoi, connecting the city center with Noi Bai International Airport and provinces in the northwest of Vietnam. The bridge stands as a lasting tribute to Soviet–Vietnamese cooperation, a role reflected in its alternative name “Friendship Bridge” and memorial features at both ends.
