Nepal’s first modern road tunnel, the Nagdhunga–Sisnekhola tunnel, is entering its final stretch. Authorities confirmed today that the project has reached 98% physical completion, with full-scale commercial operations now projected to begin by mid-July 2026.
Final Technical Hurdles
While the heavy construction is largely finished, the opening hinges on two critical remaining tasks:
-
Operator Selection: The government is in the final stages of signing an agreement with the Yusin–ART JV (a Chinese-Nepali joint venture) to manage the facility for the next five years.
-
Infrastructure & Safety: Work is currently focused on completing the toll plazas and finalizing slope stabilization on the Dhading side to prevent landslides during the upcoming monsoon season.
Trial Phase and Training
Project Director Saujanya Nepal stated that a test operation (trial run) is likely to commence in the second week of May. During this period, approximately 150 newly recruited staff will undergo specialized training. This training includes:
-
Managing the sophisticated 24-hour ventilation (jet fan) and lighting systems.
-
Operating surveillance cameras (CCTV) and emergency response protocols for fires or breakdowns.
-
Managing the automated toll collection systems.
Toll Fees & Restrictions
The Ministry of Physical Infrastructure and Transport has already gazetted the toll rates. Light vehicles like cars and vans will be charged Rs. 65 for entry into Kathmandu and Rs. 60 for exit. Heavier vehicles, such as multi-axle trucks, will face fees up to Rs. 600.
Strict safety guidelines will also be enforced:
-
Prohibited: Pedestrians, two-wheelers, three-wheelers, and non-motorized vehicles.
-
Hazmat Ban: Vehicles carrying flammable or explosive materials must continue to use the existing winding Nagdhunga-Sisnekhola road.
Once fully operational, the 2.68 km tunnel is expected to slash travel time through the notorious Nagdhunga climb from nearly 45 minutes to just 7 minutes, providing a significant boost to the capital’s main supply artery.
