The Sino–Korean Friendship Bridge, Sino–Korea Friendship Bridge, or China–North Korea Friendship Bridge (renamed from Yalu River Bridge in 1990) connects the cities of Dandong, China and Sinuiju, North Korea, along the China–North Korea border. It was constructed by the Imperial Japanese Army between April 1937 and May 1943, during their occupation of Korea and Manchukuo, to span the Yalu River. One of the few ways to enter or leave North Korea, it carries automobile and rail traffic.
