Supyogyo is an old stone bridge from Cheonggyecheon, now located in Jangchungdan Park in Seoul. It takes its name from the water-level gauge that was set up there, and an early Joseon wooden bridge was later replaced with a stone one. The bridge was removed in 1958 during the Cheonggyecheon covering project and moved to its current site in 1965. It is crowded on weekends and holidays.
