An overpass runs right beside Independence Gate in Seoul because in 1979 the gate moved 70 meters

Independence Gate (Dongnimmun) in Seodaemun, Seoul, a stone gate more than a century old, now has an overpass running right beside it. The gate once stood in the middle of Uiju-daero, but its spot collided with the route of an overpass linking Sajik Tunnel and Geumhwa Tunnel, so in 1979 it was moved 70 meters to the northwest and rebuilt. We attached the institutional source to each sentence of the video.

How we checked

Checked October 5, 2026. We compared the video against the original texts of the Korea Heritage Service's National Heritage Digital Service entry "Independence Gate, Seoul" (description and chronology table), Seoul Archives (the "Stories from the Collection" post "Records of the Relocation of Independence Gate" and the records content "Records of the Relocation of Independence Gate" and "Independence Gate"), the Seoul Museum of History exhibition notice "The 120-Year Journey of Independence Gate," and the entry "Independence Gate, Seoul" in the Encyclopedia of Korean Culture, compiled by the Academy of Korean Studies. Every sentence in the video was confirmed by an institutional source, so there is no sentence confirmed only by news reports (△).
  • Institutional sources differ on when the work of moving the gate was finished, January 1980 (Encyclopedia of Korean Culture) and August 1980 (History Net), so the video gave only the completion date of the Independence Gate Park work recorded by Seoul Archives (March 31, 1980).
  • The tunnels the overpass links are "Sajik Tunnel and Geumhwa Tunnel" in Seoul Archives and "Geumhwa Tunnel and Seongsan Tunnel" on History Net; we followed Seoul Archives, which transcribes Seoul city records.
  • The year Independence Gate was completed is 1897 in the Encyclopedia of Korean Culture and Seoul Archives and 1898 in the Korea Heritage Service, so the video said only "more than a hundred years old."
  • "It was rebuilt just as it had been" refers to its outward appearance. An institutional source says the 1928 repairs left the structure different from the original, so the two accounts were not linked.
  • "Cars went around it with the gate in the center" is based on the institutional source saying the area was called the "Independence Gate rotary"; no source separately describes how traffic moved.
  • The number of stones, the cost of the move, and the method of taking the stones apart and fitting them back together were not found in institutional sources, so the video did not mention them.
  • We do not list personal names or street addresses.
