Additional Station Added to Line 7 Cheongna Extension... Opening Scheduled as Planned in 2027

Newly Established 'Domgujang Station' to Open in March 2029

Incheon City will open the Seoul Subway Line 7 Cheongna extension as scheduled in 2027, but considering the increasing transportation demand, it has decided to additionally construct the 'Domgujang' Station and open it in March 2029.

On the 24th, Incheon Mayor Yoo Jeong-bok held a press conference and announced, "We will build an additional station on the Seoul Line 7 Cheongna extension and prepare plans to shorten the construction period to open it in 2027 as originally planned."

The city plans to build a provisional Domgujang Station due to the expected large-scale transportation demand from the opening of a 20,000-seat dome stadium in Starfield Cheongna in 2027 and the opening of the Cheongna Medical Complex Town (Seoul Asan Hospital) in 2029. With the addition of Domgujang Station between Gukje-eobmu-jigu Station and Cheongna International City Station, the number of new stations on the Cheongna extension line will increase from seven to eight.

The city will prioritize opening the currently under-construction Cheongna extension line and its seven stations in 2027, while Domgujang Station will be passed through without stopping until its completion, with plans to open in March 2029. To this end, the city plans to obtain approval for total project cost adjustments by September through consultations with the government and start construction of Domgujang Station by the end of next year.

The Cheongna extension line is being constructed over a 10.7 km section connecting Seoknam Station, the current terminus of Line 7 in Incheon, through Cheongna International City to the Airport Railroad (Cheongna International City Station). Construction began in February last year and currently shows a progress rate of 11.9%. Once Seoul Line 7 is extended to Cheongna International City Station, travel time from Cheongna to Seoul Guro will be reduced from the current 78 minutes to 42 minutes, and access to Gangnam will be possible without transfers, significantly improving Seoul accessibility.

Incheon City planned last September to proceed with design changes to the existing line under construction to build the additional station. However, after the Ministry of the Interior and Safety's legal interpretation and a recent audit by the Board of Audit and Inspection confirmed that the design changes violated laws and regulations, the city could no longer proceed with design changes and decided to add the new station on the main line of the existing route.

Additionally, anticipating delays in the opening of the Cheongna extension line scheduled for 2027 due to the new station construction, the city recently held a joint meeting with field experts and, after technical review, devised a plan to shorten the construction period by about 12 months. Measures include reducing tunnel excavation divisions (from 9 divisions to 7), adjusting the number of daily blasts (from 2 daytime blasts to 3 blasts day and night), extending intervals for tunnel lining placement, and adding formwork to shorten the construction period.

Mayor Yoo said, "We decided to add the new station for the convenience of citizens' transportation," and added, "We will do our best to open the line in 2027 as promised to the citizens by applying the construction period shortening plan." He emphasized, "The Seoul Line 7 Cheongna extension will bring innovative changes to the Incheon Free Economic Zone Cheongna International City, leading not only to improvements in the business environment but also to the development of Incheon City."
