Why was the Cheonggyecheon in Seoul a damaged urban river?

The stream was polluted and covered with concrete after the Korean War, and an elevated highway carrying about 168,000 vehicles a day was built above it.

What were the aims of the Cheonggyecheon restoration project?

To remove the decaying highway, restore the stream as a green corridor, reduce pollution and heat in central Seoul, and regenerate the surrounding business district.

When was the Cheonggyecheon restoration carried out and how much did it cost?

Work began in July 2003 and the 5.8 km stream opened in October 2005, at a cost of about 387 billion won (roughly US$281 million).

Where does the water in the restored Cheonggyecheon come from?

About 120,000 tonnes a day are pumped from the Han River and from groundwater in subway stations, because the natural stream is dry for much of the year.
