    • Seoul to create “urban forests” along three car-only expressways, such as the Olympic-daero, the Gangbyeonbuk-ro, and the Dongbu Ganseon-ro
    • This is a part of the “Plant 2022-30 Million Giving Trees” project with an aim to increase green areas in the city
    • Seoul plans to spend 16 billion won (US$ 13 million) by stages to plant around 2.1 million trees suitable to the road’s poorer growing conditions

    SEOUL, SOUTH KOREA, August 7, 2019 – Green areas will be created along the Olympic-daero, an asphalt-covered expressway located in Seoul an average of 250,000 cars a day are driven.

    According to the Seoul Metropolitan Government, around 2.1 million trees will be planted along three car-only expressways – the Olympic-daero, the Gangbyeonbuk-ro, and the Dongbu Ganseon-ro – by 2022. This is a part of the “Plant 2022-30 Million Giving Trees” project announced by the Seoul Metropolitan Government in March this year with an aim to increase green areas in the city.

    For this project, the Seoul Metropolitan Government plans to spend a total of 16 billion won (US$ 13 million) by stages from the second half of this year to 2022 to plant around 2.1 million trees.

     Stage 1 (2019): 176,000 trees
     Stage 2 (2020): 733,000 trees
     Stage 3 (2021): 487,000 trees
     Stage 4 (2020): 704,000 trees

    Since the three expressways are the busiest roads in Seoul, a great amount of exhaust gas is generated. It is expected that planting trees there will provide a practical solution to the ever-worsening environmental problems such as fine dust and heat island effect. Also, it will help improve the landscape of automobile-only roads by planting trees with seasonal characteristics.

    Considering the road’s poorer conditions for growing plants, the Seoul Metropolitan Government will select and plant trees suitable to that conditions based on the research result of the “Species of Trees and Planting” conducted by the Seoul Institute of Technology, and fine dust-reducing trees designated by the Korea Forest Research Institute.

    A city official said, “Creating urban forests around the dreary asphalt driveways is a paradigm shift in space and function. We will actively involve in the creation of more green spaces in the city to tackle environmental problems such as fine dust and heat waves.”
