Shuaiwanzi Border Bridge

　　Shuaiwanzi Border Bridge, named after Shuaiwanzi Village in Ying'an Township. The bridge was completed in 1938, and in 1945, when the Japanese army retreated from northeastern China, the Soviet Red Army blew up one span of the middle section to cut off the Japanese retreat. The bridge is 486.5 meters long, 6.5 meters wide, and has 32 spans.

　　In addition to the border highway bridge connecting to North Korea here, there was also a railway bridge linking to North Korea. However, in August 1945, after Japan's surrender and the entry of the Soviet Red Army, all the iron girders of this bridge were dismantled. Now only a row of bridge piers remains standing in the Tumen River, telling the story of the past.
