The towers feature a skybridge (constructed by Kukdong Engineering & Construction) between the two towers on 41st and 42nd floors. The bridge is 170 m high and 58 m long. The same floor is also known as the podium, since visitors desiring to go to higher levels have to change elevators here. The skybridge is open to all visitors, but passes (limited to around 1400 people per day, which usually run out before noon) must be obtained on a first-come, first-served basis. Passes are free. The skybridge is closed on Mondays.
