The Military Demarcation Line runs through the middle of the bridge. At the end of either side of the bridge are guard houses of the respective countries. The North Korean building is called KPA#4 while the United Nations Command checkpoint was called CP#3 (it was abandoned in the mid-1980s). CP#3, which is surrounded by trees, was only visible from one other UNC site during the winter months, OP#5 (now renamed to CP#3). The North's Korean People's Army (KPA) had made numerous attempts to grab UNC personnel from the old CP#3 and drag them across the bridge into North Korean territory.
