The roads identified by JKR Sarawak are the Jalan Bintulu/Tatau Junction (Mile 5)–Bintulu Port route and Jalan Tanjung Kidurong. Inspections found surface deterioration on several sections, with continuous heavy-vehicle movement cited as one contributing factor.

The repair plan will take site conditions, safety requirements and traffic management into account. JKR also says the locations will be monitored during the works and motorists should follow signs and traffic-control instructions.

No full closure timetable was announced in the update. For road users, the practical change is to stay alert for work zones around two routes that carry both public traffic and industrial logistics.
