[Asia Economy Reporter Park Jong-il] Gangdong-gu (Mayor Lee Soo-hee) held a progress report meeting at 3 p.m. on the 12th with the construction companies of Phase 4 extension of Seoul Subway Line 9: Daewoo Construction Consortium (Section 1), Taeyoung Construction Consortium (Section 2), and Hanshin Engineering Consortium (Section 3).

The Phase 4 extension project of Seoul Subway Line 9 is a project to build four new stations along a 4.12 km section starting from Jungang Veterans Hospital Station in Gangdong-gu, passing through Gildong Ecological Park Intersection, Hanyoung High School, and Line 5 Godeok Station, extending to Godeok Gangil 1 District. The Seoul Metropolitan Government’s Urban Infrastructure Headquarters is overseeing the construction.

The project is divided into three sections. On August 31, 2021, Section 2, from Daemyeong Elementary School Intersection to Godeok I-Park Apartment (1.289 km, tentatively named Hanyoung High School Station and Godeok Station), began construction. On December 30, 2021, Section 1, from Jungang Veterans Hospital Station to Daemyeong Elementary School Entrance Intersection (1.348 km, tentatively named Gildong Ecological Park Station), and Section 3, from Godeok I-Park Apartment to Godeok Gangil 1 District (1.485 km, tentatively named Godeok Gangil 1 Station), also commenced construction. All three sections are scheduled for completion in 2028.

At the progress report meeting held that day, Gangdong-gu and each construction company shared the current status and future plans of the Line 9 Phase 4 construction, established an active cooperation system for necessary permits and approvals, and set up an information-sharing system. The district plans to continuously utilize this information-sharing system with the Seoul Metropolitan Government and construction companies to provide residents with real-time updates on the project’s progress.

Previously, since the Ministry of Land, Infrastructure and Transport announced candidate sites for the public housing district in 2011, the district proactively requested transportation measures and included the Line 9 Phase 4 project in the Ministry’s 2012 comprehensive transportation improvement plan for the Godeok and Gangil public housing districts.

Additionally, in 2015, the project was incorporated into Seoul’s 10-year urban railway network construction master plan. Subsequently, it passed the preliminary feasibility study in May 2018, received basic plan approval in April 2020, and was confirmed as a turnkey project in June 2020. Throughout these critical stages, the district has actively supported the Line 9 Phase 4 extension project for over ten years.

As a result, all three sections were able to start construction by the end of 2021, and on August 9, the Seoul Metropolitan Government completed the final project plan approval application to the Ministry of Land, Infrastructure and Transport. Once final approval is granted in October, full-scale construction such as excavation will commence.

Furthermore, the district announced that the additional extension project of Line 9 Phase 4, from Godeok Gangil 1 District to Gangil-dong (1.25 km), is also progressing smoothly.

The additional extension section of Line 9 Phase 4 was included in the Namyangju Wangsuk District comprehensive transportation improvement plan in December 2020. On July 5, 2021, the Ministry of Land, Infrastructure and Transport officially designated the Gangdong, Hanam, Namyangju Line (18.1 km) as a new project in the 4th National Railroad Network Construction Plan (2021?2030) (Ministry of Land, Infrastructure and Transport Notice No. 2021-936), and the project is currently underway.

In September, it passed the preliminary feasibility study for public institutions, and Gyeonggi Province is currently conducting feasibility evaluations and basic plan establishment. The study is expected to be completed by September 2023, and if the basic plan is approved by the end of 2023, construction will begin following basic and detailed design procedures.

Lee Soo-hee, Mayor of Gangdong-gu, stated, “In addition to the advanced business complex established in 2015, Godeok Biz Valley and Gangdong General Industrial Complex are newly being developed, and large-scale reconstruction and housing development projects are actively underway, marking the most dynamic period of change since the district’s establishment. We must proactively respond to the increasing transportation demand in line with these changes.”

He added, “Gangdong-gu plans to promptly complete the ongoing subway Line 8 and 9 extension projects to become the transportation hub of the eastern metropolitan area. We will also ensure the successful promotion of the Line 5 direct connection project and the attraction of the GTX-D line to Gangdong-gu.”
