Incheon-Gimpo Clash Over Stations on Seoul Line 5 Extension

Incheon and Gimpo cities remain at odds over a key riding-station plan tied to the extension of Seoul Subway Line 5 toward Gimpo and the Gaemdan area. Even as the project won preliminary feasibility approval, how many new stations should be built in the Incheon segment is fueling a fresh dispute between the two local governments.

The extension would run about 25.8 kilometers from the Banghwa vehicle depot to the Gimpo Hangang 2 public housing district, passing through Incheon Geomdan and Gimpo’s Gocheon and Pungmu areas. The core disagreement concerns station placement: Incheon wanted four new stations in its segment, while Gimpo argued for just one.

In the end, the council overseeing major metropolitan transport questions, under the Ministry of Land, Infrastructure and Transport, issued a mediation proposal that included two new stations in Incheon. Despite that compromise, the project’s feasibility study was approved on the 10th, signaling formal support for the plan to extend the line with those Incheon stations.

During the feasibility review, Incheon did not publicly oppose the mediation and signaled it would push ahead with station plans after the study’s conclusion. Once the 예타 (preliminary feasibility) was approved, Incheon immediately announced a focus on creating a new station in a high-density residential area known as Wondang Station.

Incheon civic groups joined the push, with the Incheon Civil Rights Forum urging that Wondang Station be included in the basic plan to promote balanced regional development. Gimpo City, however, staunchly opposed adding any more stations in Incheon, arguing that an additional Incheon stop would impose costs or time burdens on Gimpo residents.

With the two cities still far apart, analysts expect the project to face a rocky path ahead. The extension has been part of Korea’s 4th National Railroad Network Construction Plan since 2021, a scheme that relies on local consensus; without agreement between Incheon and Gimpo, project progress remains uncertain.

For non-Korean readers, this dispute underscores how Seoul’s sprawling transport ambitions hinge on local cooperation. The outcome could influence commute times, housing and business development, and regional connectivity in one of Asia’s largest urban economies. Given Korea’s role in global supply chains and technology manufacturing, delays or changes to this extension could affect regional labor markets, cross-border travel for business, and the timetable for future rail projects that connect major hubs around Seoul, Incheon, and Gimpo.
