DANDONG, China, Sept. 28 (UPI) -- A 72-year-old railroad bridge connecting North Korea and China was closed after a crash involving multiple trucks occurred on the North Korea side of the span on Monday.
The Yalu River Bridge, also known as the Sino-Korean Friendship Bridge, was blocked after three or four Chinese trucks rolled at a portion of the bridge that had sunk between 13 and 22 feet, South Korean news network YTN reported.
The bridge has a lane for road vehicles and another for a pair of railway tracks. Trains traveling from China into North Korea were temporarily suspended, but service was resumed after the tracks were repaired, an unidentified source told YTN on Monday.
Another source told South Korean outlet CBS No Cut News the heavy trucks headed for Sinuiju overturned, fell and collided into the adjacent railway tracks, and the accident occurred between 10 and 11 a.m. Vehicular traffic was closed for the rest of the day, and more than 100 trucks from China waiting to enter North Korea were halted, the source said.
The number of casualties was not disclosed.
The bridge, completed in 1943, accounts for 70 percent of commercial traffic between China and North Korea, and the railroad runs from Sinuiju to Beijing.
China remains North Korea's No. 1 trading partner, and North Korea imports more than it exports to Asia's largest economy. Pyongyang's trade dependence on China runs as high as 90.1 percent, according to South Korean government statistics.
