Chalong Underpass will be closed in order to conduct maintenance works to the lighting and water drainage system in the tunnel, the Phuket Highways Office announced in a notice.
The underpass will be closed from 9am to 3:30pm. No further information was provided.
Commenting on similar closers before, Phuket Highways Office Chief Samak Luadwonghat explained that officials specifically avoid conducting maintenance during the rush hours.
“To explain why our officers do not conduct the work at night, we need sunlight when we shut down the lights in the tunnel. This helps our officers to do the work more easily,” Mr Samak explained.
The most recent closure was in late November – early December last year. The underpass was closed during the same daylight hours for around three weeks. No significant traffic congestion was reported.
