A stream runs through the center of Seoul, dividing the city into North and South, but for three decades it was totally buried beneath a busy downtown highway. In 2003, as part of a vast urban renewal project, the highway was removed and the stream was recovered and turned into a beautiful 5.8 km urban park.
Considered an example of "successful industrialization and modernization", the highway remained there until 2003, when city planners tore it down to revitalize the area and help Seoul remake itself as a modern environmentally friendly city. The Cheonggyecheon Restoration Project took two years and cost around $281 million, but it has created a thriving stretch of green public space in the middle of the city.
In addition to the restoration project, Seoul has also implemented transportation planning, rerouting traffic through other corridors and adding more public transportation. As a result there has been a decrease in the number of vehicles entering the city and bus and subway use has increased. Even though the city took away one of the major thoroughfares, they were able to redirect and decrease traffic through efficient planning and expanded public transportation.
