A main road in Ta’’s Tha Song Yang district was blocked by soil and trees that down from mountains due to flash floods on Wednesday morning.
A tourist-destination cave also had to be closed, authorities said.
Prasong Lar-on, the Tha Song Yang district chief, directed workers from the Tak Highway office, district officials and volunteers using heavy equipment to clear the blocked Mae Sot-Mae Sariang road.
The landslides followed days of heavy rain.
Officials closed the Mae Usu Cave after its entrance was flooded by mountain run-off.
