BANGKOK, THAILAND – A vast sinkhole has blocked emergency access to a major Bangkok hospital for more than seven weeks, driving political tension and community frustration over delayed repairs.
The 30×30‑meter cavity outside Vachira Hospital in Dusit District has remained closed since 24 September 2025, halting ambulance routes and daily commutes for over 12,000 vehicles using Samsen Road.
Officials decry prolonged disruption
City Administrative President Wiput Sriwaurai criticised the ongoing closure.
“The repair works are still not completed 51 days after the collapse.”
said Wiput Sriwaurai, City Administrative President.
The protracted blockage has restricted access for patients, students and residents, forcing emergency crews to take lengthy detours during rush hour.
Prime Minister’s promise unmet
Prime Minister Anutin Charnvirakul had pledged swift restoration when inspecting the site in early October.
“The road shall be restored by October 9.”
said Anutin Charnvirakul, Prime Minister.
However, construction firms Ch. Karnchang and Sino‑Thai Engineering, also responsible for the MRT Purple Line tunnel project, have failed to meet deadlines. Both face rising scrutiny over their handling of the operation.
Political pressure mounts for accountability
Administrative leaders demanded compensation for the public cost of the delay.
“The delays cause expenses not only for the contractors but also for the local residents.”
said Wiput Sriwaurai, City Administrative President.
Member of Parliament MR Kritchon Aiyapanya called for prosecution.
“The companies involved must be held accountable.”
said MR Kritchon Aiyapanya, Member of Parliament.
Officials estimated that temporary barriers and infrastructure repairs had cost millions of baht while ambulances continued using alternative routes.
Cause remains undetermined
Preliminary experts suggested that soil infiltration into a finished tunnel section may have triggered the subsidence, but investigators have released no official results. Yanakitt Huangsap, overseeing inspection safety, warned of larger concerns.
“Similar incidents must urgently be prevented.”
said Yanakitt Huangsap, Project Inspection Official.
Traffic gridlock and public disruption
The closure of the Samsen Road intersection worsened congestion throughout Dusit District, according to Bangkok Metropolitan Department counts showing thousands of delayed commuters daily. Street vendors and nearby businesses reported income losses, while market operators appealed for municipal relief funds.
Recovery and investigation ahead
Local council members reported a round‑the‑clock repair schedule under city supervision to reopen the corridor in November 2025. Lawmakers also called for technical audits of other Bangkok underground transport projects to avert renewed collapses.
“Public confidence in the safety of urban infrastructure must be restored.”
said Wiput Sriwaurai, City Administrative President.
Authorities confirmed that full reopening would occur only after structural certification by transport engineers. Until then, ambulances continue operating through secondary streets as crews work to stabilize the 20‑meter‑deep site.
- Sinkhole dimensions: 30×30 meters wide, over 20 meters deep
- Closure date: 24 September 2025
- Blocked traffic: approx. 12,000 vehicles daily
- Construction firms: Ch. Karnchang and Sino‑Thai Engineering
The Bangkok Metropolitan Authority aims to conclude both repairs and legal reviews within the next month, but the damaged intersection remained sealed behind concrete barriers on Day 51 of the shutdown.
