GTX-C Main Construction to Begin Sept. 15: Deokjeong–Samseong Trip Planned to Drop from 80 to 30 Minutes
South Korea’s Ministry of Land, Infrastructure and Transport said construction on the GTX-C public-private partnership project will begin on September 15, 2026. The approximately 86.6-kilometer line will connect Deokjeong-dong in Yangju with Suwon Station and Sangnoksu Station. Construction is scheduled to last 60 months from its start. The travel-time reductions between Deokjeong and Samseong, and between Suwon and Cheongnyangni, are plans; no opening year has been confirmed.
