A massive sinkhole measuring about 30 by 30 meters and 50 meters deep opened on Samsen Road in front of Vajira Hospital on Wednesday morning.
Several vehicles were damaged and nearby buildings, including the hospital and a police station, were evacuated as a precaution. Utilities were cut off and traffic in central Bangkok ground to a halt.
Officials say the collapse is likely linked to construction on the Purple Line railway project. No fatalities have been reported.
Authorities are working to stabilize the site and investigate the cause.
