Cheonggyecheon is a 5.8 km creek flowing west to east through downtown Seoul, and then meeting Jungnangcheon, which in turn connects to the Han River and empties into the Yellow Sea. During the presidency of Park Chung-hee, Cheonggyecheon was covered with concrete for roads. In 1968, an elevated highway was built over it. In July 2003, then-Seoul mayor, Lee Myung-bak initiated a project to remove the elevated highway and restore the stream.
