2006: Seoul, South Korea

Under the leadership of Mayor Myung Bak Lee, a four-mile elevated highway that once covered the Cheonggyecheon River in the city center was replaced with a riverfront park, high quality walkways, and public squares. Exclusive bus lanes were constructed along 36 miles of congested streets, and the city government initiated plans for additional bus lanes as part of a broader initiative to improve all aspects of the city’s bus system.
