The purpose of this study is to propose a set of revival program, to give Seoul, a sense of nature and monumentality, the history of urban planning is totally erased from the new Seoul. And it lack today a sense of orientation and context. The design and construction aspects of the Cheonggyechon Restoration Project in Seoul, Korea are presented in this book. The Cheonggye-chon('chon' means a stream) is a stream that flows from west to east across the northeastern quarter of Seoul. It had been covered by a concrete deck structure, served as a roadway that had been one of the capital's major arterials. An elevated expressway above the road was built to handle increased traffic loads. Due to several reasons, it was decided to remove the concrete roadway and the elevated expressway, and restore the environmental health of the stream. This renewal project not only brings environment-friendly eco-system to the area, but also promises a new economic life into the area.
