[Asia Economy Reporter Ra Young-cheol] The Seohae Line (Daegok~Sosa) Han River underwater tunnel was pierced through after a difficult construction period of 32 months since groundbreaking.

Goyang City announced on the 12th, "The shield TBM tunnel of the Seohae Line (Daegok~Sosa) double-track railway Han River underwater section was pierced through on the 11th," adding, "The Seohae Line is scheduled to open in January 2023."

According to the city, this section was the most challenging construction segment of the Seohae Line (Daegok~Sosa) due to the large amount of water inflow during the Han River underwater excavation and difficult working conditions such as the complex strata beneath Jayuro. The excavation period took 32 months.

With this tunnel breakthrough, the extension project of the Seohae Line (Daegok~Sosa) double-track railway to Ilsan Station is gaining momentum, and simultaneous opening in January 2023 is expected.

The detailed design for the Ilsan Station extension is currently in its final stages, and the plan is to start construction of the Ilsan Station extension project in December and open it simultaneously with the Seohae Line (Daegok~Sosa) section in January 2023.

The city has invested a total of 26.3 billion KRW in the Seohae Line (Daegok~Sosa) and plans to invest an additional 8.6 billion KRW for the Ilsan Station extension.

Lee Jae-jun, mayor of Goyang City, expressed his expectations, saying, "Once the Seohae Line project is completed, Gimpo Airport, Bucheon, Siheung, and other southern and western parts of Seoul as well as southern Gyeonggi will be connected by rail, making Goyang a transportation hub in the metropolitan area."
