Cheonggyecheon (Hangul: 청계천) is a nearly 6 km long, modern public recreation space in downtown Seoul, South Korea. The massive urban renewal project is on the site of a stream that flowed before the rapid post-war economic development required it to be covered by transportation infrastructure. It was a $900 million project.
During the 1948-1960 presidency of Syngman Rhee, Cheonggyecheon was covered with concrete for roads. In 1968, during the presidency of Park Chung-hee, an elevated highway was built over it. In July 2003, then-Seoul mayor, President Lee Myung-bak initiated a project to remove the elevated highway and restore the stream. It was a major undertaking as not only did the highway have to be removed, but as years of neglect and development had left the stream nearly totally dry, 120,000 tons of water had to be pumped in daily. At that time, safety problems also occurred due to the deteriorated concrete construction. Despite this, restoration of Cheonggyecheon was deemed important as it fitted in with the movement to re-introduce nature to the city and to promote a more eco-friendly urban design.
The stream was opened to the public in September 2005 and was lauded as a major success in urban renewal and beautification.
