Following a road collapse on the Tarutung–Sipirok–Padangsidimpuan route in South Tapanuli caused by a landslide on October 18, emergency repairs were completed to restore access for small and large vehicles. Brigjen TNI Fadjar Tjahjono noted that while access is restored, permanent repairs and monitoring are necessary to prevent future incidents.

Subsequent infrastructure efforts in the Tapanuli regions include the construction of a concrete bridge in North Tapanuli, which has reached 79 percent completion. Additionally, in South Tapanuli, the Public Works and Spatial Planning Department is installing gabions for road protection in Angkola Selatan to mitigate risks from landslides and flooding. This project is expected to be finished by the end of November 2026.
