KIULU - More than 20,000 villagers were cut off for about 12 hours when a mudslide hit Jalan Tamparuli-Kiulunear Kampung Rangalau Baru here on Monday.
The mudslide covered the 4.8km road at 2.30pm.
Vehicles were stranded, causing heavy traffic in both directions.
Firefighters were sent to inspect the site.
No casualties were reported.
Power supply in the district was disrupted but was restored later.
Alex Yassin, 55, a Kampung Malanggang Baru villager, said earth movement was detected an hour before the mudslides occurred because of a downpour earlier.
Former district people's development leader, Sami Bungud, said soil from Jalan Bungalio-Logub Baru construction on a nearby hill could have caused the landslide.
Kiulu assemblyman Datuk Joniston Bangkuai said the road was accessible since 5am yesterday and clearance work was continuing.
"I have visited the site. The road can now be used by villagers, including tourists who plan to go water rafting at the Kiulu river."
