The Pahala Kadugannawa area on the Colombo Kandy main road will remain closed until further notice, Kegalle District Secretary, Mahinda S. Weerasooriya said.
The landslide threat was detected yesterday near the 98th km post on the Colombo-Kandy main road.
Earlier, it was decided to allow only light vehicles to pass through that area using one lane, but the Road Development Authority (RDA) advised closing the area due to possible landslide threats.
RDA requested motorists to use alternative routes to reach Kandy and Colombo.
