Governor Chadchart has ordered the evacuation of residents within a 30-meter radius due to a water leak in the MRT tunnel after further road subsidence. Pradit Phong Road is closed from Ban Khaek Intersection to Wongwian Yai to reduce vibrations amid concerns over potential building collapse, with continuous monitoring of subsidence underway.
9 July 2026 GMT+7 Mr. Chadchart Sittipunt, Governor of Bangkok together with Mr. Wisanu Subsompon, Deputy Governor of Bangkok, visited the site to monitor progress on the incident. A water leak in the MRT tunnel under construction near Wongwian Yai on Pradit Phong Road. Governor Chadchart disclosed after a progress meeting with relevant parties at 18:45 that the leak occurred at the project's lowest point, causing it to collect water which flowed into the tunnel. Additionally, the surrounding soil subsided inward. Contractors are currently addressing the issue.
Currently, the Bangkok Metropolitan Administration is managing the surrounding situation by monitoring whether the rate of water leaking into the tunnel is increasing, whether the soil amount has increased, and whether the subsidence rate of the surrounding soil has worsened, to assess if further damage is occurring. Contractors recommended inspecting and monitoring the area within a 30-meter radius from the incident point and evacuating residents from three buildings around Pradit Phong Road, totaling about 60 people, for a period of one week. They will be temporarily relocated to safe places such as hotels, with contractors hired by the Mass Rapid Transit Authority of Thailand (MRTA) responsible for all expenses and compensation.
The second measure concerns traffic management. To ensure safety and reduce vibrations, Pradit Phong Road will be closed to traffic. Third, a command center has been established at the incident site to coordinate and manage the situation. Inspections show that Pradit Phong Road’s subsidence has increased but is starting to stabilize, requiring continuous monitoring. The main goal is to stop water from flowing in and prevent soil from entering the affected area.
Additionally, traffic on Pradit Phong Road has been closed from Ban Khaek Intersection to Wongwian Yai, covering over 200 meters, to reduce vibrations and prevent commercial buildings from collapsing. The Department of Disaster Prevention and Mitigation has installed additional automatic building movement sensors to provide immediate warnings if further subsidence occurs. Furthermore, residents traveling from Phut Bridge or Phra Pok Klao Bridge are advised to turn at Ban Khaek Intersection and use Isaraphap Road, Lat Ya Road, or Somdet Chao Phraya Road as alternative routes.
Plans are also in place to mitigate impacts on local schools, since the area is a bottleneck with several large schools, including Suankularb Wittayalai School and Satri Naree School. Concerned about long-term traffic problems, authorities plan to apply lessons learned from previous subsidence cases near Vajira Hospital, such as at Saint Gabriel's and Saint Francis Xavier Convent schools. Additional school shuttle buses may be arranged to reduce parental vehicle congestion, and detailed route information will be communicated to the public.
Meanwhile, the Department of Disaster Prevention and Mitigation has deployed special equipment, support vehicles, power generators, and balloon lights to facilitate nighttime operations at the site. Volunteers and various foundations are also providing support in case of emergencies requiring medical transfer.
