KATHMANDU: The commercial operation date of the Nagdhunga–Sisnekhola Tunnel Road has once again become uncertain, despite the government’s earlier announcement to bring the project into operation by January 1, 2026.
The delay has been caused by two major factors: prolonged selection of a company to operate and manage the tunnel, and the time required to construct toll plazas at both ends of the tunnel.
Director General of the Department of Roads, Dr. Bijay Jaisi, said that although necessary procedures are underway, it is no longer possible to fix a definite date for commercial operation. “All works are in process, but we cannot confirm a specific date for commercial use of the tunnel,” he said.
According to Jaisi, a major landslide has occurred at the Dhading-side entrance of the tunnel, requiring a permanent solution that can withstand the monsoon season. The toll plaza will be constructed at the same location only after the landslide is fully stabilized. Similarly, construction of the toll plaza on the Kathmandu side has also not been completed.
Until the toll plazas are built, commercial operation of the tunnel will not be allowed, as users are required to pay toll charges. While vehicles can technically pass through the tunnel, Jaisi said commercial operation requires completion of all legal and administrative procedures.
Project officials have warned that without long-term mitigation measures at areas affected by land subsidence, the tunnel’s entry and exit points could face serious risks during heavy rainfall.
Meanwhile, the Department of Roads is preparing to hand over tunnel operation and management to a specialized company. A tender has been issued, but its deadline has already been extended twice, with the latest deadline set for January 14.
The Nagdhunga–Sisnekhola Tunnel is 2,688 meters long and is expected to reduce travel time between Naubise and Kathmandu to around 20 minutes once operational.
