Massive Sinkhole Opens on Bangkok’s Samsen Road, Forcing Evacuations and Hospital Service Disruptions

Early findings point to soil loss at an MRT tunnel–station work site aggravated by a ruptured water pipe, with a formal probe under way.

Overview

  • No injuries were reported after a crater about 30 by 30 meters and roughly 50 meters deep formed in front of Vajira Hospital on Wednesday morning.
  • Three vehicles and multiple power poles were swallowed or damaged as a burst water main poured into the hole and utilities were cut off for safety.
  • Traffic was closed between the Vajira and Sanghi intersections, nearby residents and the Samsen police station were evacuated, and severe congestion followed.
  • Vajira Hospital suspended outpatient services and is rescheduling thousands of appointments, while authorities said the hospital’s main structures remain safe.
  • The Mass Rapid Transit Authority and city agencies cordoned the site, deployed engineers and drones for stabilization, and warned that ongoing monsoon rains could complicate repairs.
