It's now been 10 years since the completion of the Cheonggye Stream Restoration Project that transformed an elevated freeway in the heart of Seoul into an 11km family friendly walkway that now attracts millions of tourists each year. While it's reported that most people in Seoul are now convinced the change was worth the trouble, the project cost more than $300 million and displaced 60,000 merchants and street vendors. KoreaFM.net visited the Cheonggye Stream and asked people what they thought of the pros and cons of the project.
