Overview

• A four-lane stretch of Samsen Road collapsed over works for the MRT Purple Line’s Vajira Hospital station, creating a crater roughly 50 by 30 meters and about 22 meters deep.
• Power and water were cut, traffic was halted, and nearby buildings were evacuated after videos showed the pavement sagging and knocking down poles and water lines.
• Vajira Hospital canceled about 3,500 appointments as outpatient services were paused for at least two days, and a police station at the edge of the collapse was cleared.
• Authorities reported no injuries, three vehicles were damaged, and a restricted zone of roughly 100 meters around the site remains in place.
• Governor Chadchart Sittipunt identified the station works as the probable cause as repairs began, and the prime minister requested a two-day inquiry led by the Bangkok governor and the metropolitan transit authority.
