Nepal’s first modern road tunnel, the Nagdhunga–Sisnekhola Tunnel Road, is now in its final stage and preparing for operation, marking a major milestone in the country’s transport infrastructure.
The tunnel, which connects Kathmandu with Dhading, is expected to ease traffic congestion along one of the busiest entry points to the capital and significantly cut travel time. First inaugurated in 2019, the project has taken longer than initially planned due to technical and geographical challenges.
Originally estimated to cost around Rs 22 billion, the project’s total cost has now risen to over Rs 27 billion. The construction was carried out by the Japanese joint venture Hazama–Ando JV with financial support from the government of Japan.
Although the main tunnel structure has been completed, some work remains. Landslide control measures and toll infrastructure on the Dhading side are still under construction. Officials say these final elements are necessary before the tunnel can be fully operational.
The operation and management of the tunnel have already been awarded to a Chinese joint venture, Yuxin–ART, under a five-year contract worth over Rs 1.1 billion.
The government has also set toll fees for vehicles using the tunnel. Light vehicles such as cars and vans will pay around Rs 60 to Rs 65 depending on direction, while larger vehicles, including buses and trucks, will be charged higher rates based on size and axle capacity.
The tunnel is expected to improve road safety and reduce travel delays along the Prithvi Highway corridor. As Nepal prepares to open this long-awaited project, it signals a shift toward more modern and efficient transport solutions in the country.
