Sinanju's bridges and railways were bombed by the United States Air Force during the Korean War to halt the transport of supplies to North Korea. During the second Korean winter, railways and bridges leading from Sinanju to Chongju were bombed by the U.S. on January 25, 1952, but were repaired five days later. During the last week of March, 1952, U.S. forces began using B-29 Superfortresses through April to destroy bridges between Sinanju and Pyongyang.
During the third Korean winter, the USAF targeted 5 railroad bridges over the Chongchon Estuary near Sinanju in January, 1953. Trains were supposed to dock in marshaling yards there. Allied bombers destroyed them at night, but this only stopped enemy transport temporarily. Consequentially, in Spring of 1953, Communist troops had more difficulty transporting troops and supplies due to relentless allied intervention.
