Seosan City describes a direct express bus service between Daesan/Seongyeon and Seoul Gangnam Central City, launched 27 May 2026, with two trips in each direction daily. Toward Seoul: Daesan 06:30 → Seongyeon 06:45 → Seoul 08:40; Daesan 14:30 → Seongyeon 14:45 → Seoul 16:40. Returning: Seoul 10:30 → Seongyeon 12:25 → Daesan 12:40; Seoul 18:10 → Seongyeon 20:05 → Daesan 20:20. The municipal poster quotes KRW 15,300 and Tmoney GO booking. It separately labels a local BOARDING point 'in front of Woomi Lin Building 103' and a local ALIGHTING point 'in front of Hillstate Building 402'. These are direction-specific labels; do not assume they represent the separate Daesan and Seongyeon boarding stops. Confirm the exact stop in each town and travel direction with Tmoney GO or the bus operator. Live seats, fares and holiday service can change.
