2003-2005年间,韩国拆除了覆盖首尔清溪川(Cheonggyecheon River)的高架公路,以便改善和美化这片地区的环境。现在,复原后的清溪川已成为一道亮丽的城市风景线,每天有9万行人从这里走过,它为全球的城市改造项目树立了榜样。在首尔历史上,清溪川有很长一段时间都曾是一条被污染的河流,经常爆发洪水,尤其是在周边地区为满足经济发展需要而对林地滥砍滥伐之后。当时的解决办法就是将河流覆盖了起来,并且于1961年将其建成了一条城市主干道。之后,在快速城市化的推动下,被覆盖的清溪川上建起了一座高架公路,公 From 2003 to 2005, South Korea demolished the elevated road covering Cheonggyecheon River in Seoul to improve and beautify the environment in the area. Now, the restored Cheonggyecheon River has become a beautiful cityscape with more than 90,000 pedestrians passing by every day. It sets an example for global urban renewal projects. In the history of Seoul, the Cheonggyecheon River has been a polluted river for a long time, with frequent flooding, especially after the woodlands were deforested in the surrounding areas to meet economic development needs. The solution at that time was to cover the river and in 1961 it was built as a city trunk road. Later, under the impetus of rapid urbanization, an elevated highway was built on the covered Cheonggyecheon River.
