Mayor Shin Sangjin: "Completion of a Thorough Transportation Network with Pangyo Extension of Line 8 and Wirye Sinsa Line Passing Preliminary Feasibility Study"

Seongnam City’s Pangyo Extension Project for Line 8 Selected for Preliminary Feasibility Study
Wirye Sinsa Line Passes Review, Signaling Green Light for Railway Network Expansion
Positive Outlook for Advancement of Wirye Samdong Line

On March 10, Seongnam City, Gyeonggi Province (Mayor: Shin Sangjin), announced that the Pangyo Extension Project of Subway Line 8 had been selected as a candidate project for the preliminary feasibility study by the Fiscal Project Evaluation Committee of the Ministry of Planning and Budget, and that the Wirye Sinsa Line urban railway construction project had successfully passed the preliminary feasibility study. As a result, momentum is building for the advancement of the Wirye Samdong Line project as well.

The Pangyo Extension Project of Subway Line 8 involves an investment of approximately 451.5 billion won to extend the line by about 3.78 kilometers from the Moran Train Depot to Pangyo Station. This extension is expected to significantly improve accessibility to major work and commercial facilities, including Pangyo Techno Valley.

To have the project selected as a candidate for the preliminary feasibility study, Seongnam City conducted a preliminary feasibility service. After passing the evaluation by the Investment Review Committee of the Ministry of Land, Infrastructure and Transport in January 2026, the project has now achieved the notable milestone of being selected as a candidate for the preliminary feasibility study by the Fiscal Project Evaluation Committee.

Previously, Seongnam City had sought to have the project selected as a candidate for the preliminary feasibility study in 2020, but withdrew the application in 2023 due to insufficient economic viability. Subsequently, through the 2024 preliminary feasibility service, the city improved the project's feasibility by incorporating major development plans such as Pangyo Techno Valley 2 and 3, Baekhyeon MICE, NCSOFT, and reconstruction of the first-generation new town leading districts. As a result, the benefit-cost ratio (B/C) was raised from 0.76 to 1.03.

Upon completion of the project, travel time between Moran and Pangyo is expected to be reduced from 30 minutes by car, 39 minutes by bus, and 24 minutes by subway, to approximately 6 minutes, resulting in a maximum reduction of 33 minutes. By directly connecting Sujeong and Jungwon districts with Pangyo, the project is also expected to contribute to balanced regional development, alleviate transportation congestion, and improve residential conditions.

Furthermore, the transfer system linking the Suin-Bundang Line at Moran Station with the Shinbundang Line, Gyeonggang Line, and Wolgot-Pangyo Line at Pangyo Station is projected to further strengthen the railway network in the southeastern metropolitan area.

Meanwhile, on the same day, the Wirye Sinsa Line urban railway construction project, which connects Wirye New Town and the Gangnam area of Seoul, passed the preliminary feasibility study, accelerating efforts to resolve transportation difficulties in the Wirye region. Residents of the Seongnam section of Wirye New Town have experienced inconvenience for 17 years, having paid transportation levies but lacking a railway network.

Seongnam City expects that, following the Wirye Sinsa Line's successful passage of the preliminary feasibility study, positive conditions will be created for the ongoing preliminary feasibility study of the "Wirye Samdong Line" project.

The Wirye Samdong Line is a route stretching approximately 10.6 kilometers from the provisionally named Wirye Jungang Station, passing through Sujeong and Jungwon districts in Seongnam's original downtown area (Eulji University–Shingu University–Industrial Complex), and extending to Samdong Station in Gwangju City. In February 2024, the project was selected as a candidate for the preliminary feasibility study by the Fiscal Project Evaluation Committee of the Ministry of Economy and Finance, and the Korea Development Institute (KDI) is currently conducting the study.

As the Wirye Sinsa Line enters the implementation phase, a positive impact is anticipated on the economic viability (B/C) and policy evaluation of the Wirye Samdong Line. In particular, the formation of a railway connection axis from Seongnam's original downtown area to the Gangnam area highlights the increased necessity for project implementation.

Mayor Shin Sangjin of Seongnam City stated, "Once the Pangyo Extension Project of Subway Line 8 is pursued, it will establish a core railway axis linking Pangyo and Seongnam's original downtown, greatly improving the transportation system in the southeastern metropolitan area. The successful passage of the preliminary feasibility study for the Wirye Sinsa Line also reflects the citizens' wishes that have endured for 17 years, and we expect this to further improve transportation conditions in Seongnam's original downtown area."

Going forward, Seongnam City plans to actively respond to the Korea Development Institute (KDI)'s preliminary feasibility study and, once approved, will proceed smoothly with subsequent processes such as establishing the basic plan, design, and construction.
