On the 20th at 9 p.m., a day before BTS's comeback concert, all vehicle traffic was blocked on Sejong-daero near Gwanghwamun Square in Seoul, where the concert venue has been set up.
According to police and the Seoul Metropolitan Government, from the north end of Gwanghwamun Square, where the stage is located, to City Hall, a stretch of about 1.2 kilometers will be restricted to traffic from 9 p.m. on the day until 6 a.m. on the 22nd, the day after the concert.
Sajik-ro and Yulgok-ro in front of Gwanghwamun will be controlled from Government Complex Seoul to Dongshipjasa starting 4 p.m. to 11 p.m. on the concert day.
Saemunan-ro and Jongno will be controlled from in front of the Four Seasons Hotel to the Seorin intersection from 7 p.m. to 11 p.m. on the concert day.
Police estimated up to 260,000 spectators could gather. In response, they decided to apply a "stadium-style crowd management method." They plan to install gates at 31 access points leading to the concert site to carry out systematic crowd dispersal and safety management.
After the concert ends, police plan to work with the organizer to guide people to move out in stages to prevent the crowd from dispersing all at once.
"BTS The Comeback Live: Arirang" will be held on the 21st at 8 p.m.
