Nagdhunga–Sisnekhola Tunnel Road O&M Project in Nepal

project partially completed

The project involves the operation and maintenance of the Nagdhunga–Sisnekhola Tunnel Road, a major national infrastructure project seen as key to easing traffic congestion at the western gateway of Kathmandu Valley, Nepal.The main traffic tunnel is 2.7 km long while the emergency tunnel stretches 2.6 km. The government has already fixed toll rates for vehicles using the tunnel road to ensure systematic revenue collection, similar to modern toll-based expressways and tunnel infrastructures in other countries. The tunnel incorporates several advanced safety, control, and monitoring technologies, including ventilation, emergency lighting, fire response, traffic monitoring sensors, and automated tolling systems.
