Seoullo 7017 is an elevated linear park and pedestrian overpass in central Seoul, South Korea, converted from a former highway overpass and opened in 2017. The project was initiated under the administration of Park Won-soon and built near landmarks such as Seoul Station, Namdaemun Market, and Namsan. It has been compared to projects like the High Line (New York City), Promenade Plantée, and urban redevelopment initiatives in Barcelona and Rotterdam.

History

The structure was originally part of the 1970s infrastructure associated with rapid post-Korean War reconstruction and the industrial expansion of the Hangang corridor, serving automotive traffic toward Jongno District and Myeongdong. After decades of debates involving stakeholders such as the Seoul Metropolitan Government, civic activists, and developers linked to the Seoul Station Overpass controversy, Mayor Park Won-soon announced a transformation program influenced by comparative studies of the High Line (New York City), Cheonggyecheon restoration, and the Busan Port redevelopment. Public consultations invoked organizations including the Korean Institute of Architects and international firms with precedents from Heatherwick Studio and James Corner Field Operations, while opponents referenced maintenance concerns raised by groups such as local business associations and transportation unions.

Design and Construction

Design teams combined local practice from firms registered with the Korean Institute of Architects and consultants experienced with projects in Paris, London, and New York City. Structural engineers considered legacy materials from the original 1970s viaduct and retrofitted supports to meet modern standards issued by the Ministry of Land, Infrastructure and Transport and safety codes applied after case studies like the I-35W Mississippi River bridge collapse informed national policy. Construction contractors coordinated with the Korea Railroad Corporation near Seoul Station and utilities coordinated with agencies such as KEPCO and Seoul Metro. The opening ceremony featured attendees from the Seoul Metropolitan Government, local legislators from Jung District, and cultural figures who had advocated for urban green space.

Features and Facilities

The elevated park runs approximately one kilometer and hosts over a hundred planting beds, seating zones, and viewing platforms overlooking sites including Namdaemun, Myeongdong Cathedral, and Namsan Seoul Tower. Facilities include lighting systems designed in coordination with the Seoul Design Foundation, wayfinding signed by the Seoul Tourism Organization, and accessible ramps compliant with standards from the Korea Disabled People's Development Institute. Event spaces have been programmed with partners such as the National Theater of Korea and local galleries like the Seoul Museum of Art for temporary exhibitions, while kiosks and cafes operate under permits from the Jung District Office.

Flora and Fauna

Planting schemes incorporate native and adapted species selected in consultation with horticulturalists from Seoul National University and botanists associated with the Korea National Arboretum. Beds contain specimens representative of regional biomes, with selections aimed to attract urban pollinators including butterflies documented by the Korean Society of Lepidopterists and bird species recorded by the Korean Ornithological Society. Urban ecology monitoring has engaged researchers from Yonsei University and Konkuk University to assess biodiversity changes similar to studies performed at the High Line (New York City) and the Promenade Plantée.

Cultural and Social Impact

The project has been positioned as a catalyst for cultural programming linking institutions such as the National Museum of Korea, the National Gugak Center, and neighborhood organizations in Namdaemun Market and Hoehyeon-dong. Cultural festivals, pop-up markets, and performances have involved collaborators from the Korean Film Council and Korean Cultural Center branches. Social initiatives targeted by the Seoul Metropolitan Government included outreach to small business owners affected near Myeongdong and consultation with heritage advocates concerned about impacts to nearby Namdaemun (Sungnyemun) and its precincts.

Transportation and Accessibility

The overpass interfaces with multimodal hubs including Seoul Station—linking to Korail intercity services, AREX (Airport Railroad) routes to Incheon International Airport, and Seoul Subway Line 1. Pedestrian connections reach bus stops serving the Seoul Bus network and nearby Namsan Seoul Tower cable car access points. Design emphasized universal access following guidelines promoted by the Korea Disabled People's Development Institute and integrated bicycle parking in coordination with local cycling advocacy groups.

Reception and Criticism

Reception has included praise from international urbanists referencing precedents like The High Line (New York City) and awards consideration from bodies such as the International Federation of Landscape Architects, while critics have cited concerns raised by merchants from Namdaemun Market and scholars from Korean University about gentrification effects observed in cases like the Meatpacking District evolution after the High Line. Urban planners and academics from Seoul National University and Yonsei University have produced mixed assessments regarding long-term maintenance budgets and equitable benefits, echoing debates from redevelopment projects in Barcelona and Rotterdam.
