Seoul city authorities will implement traffic control measures around Gwanghwamun Square ahead of the “BTS 2026 Comeback Show @Seoul” on the 21st.

Subway trains will pass without stopping at Gwanghwamun, City Hall, and Gyeongbokgung stations due to expected congestion, and some station exits may be closed.

Several bus routes will be temporarily diverted, while the city’s public bike service “Ttareungi” will also suspend rentals and returns in the area.

Officials said disorderly activities such as overnight waiting or lining up on sidewalks will be strictly controlled to maintain safety.

BTS will release their new album “ARIRANG” on the 20th at 1 p.m.
