Prithvi Highway Prithvi Highway is a principal highway corridor in Nepal connecting Kathmandu, Hetauda spur routes and Pokhara via the Trishuli River valley. The route serves as a primary link between the Bagmati Province and Gandaki Province, supporting transit between the Kathmandu Valley, the Gorkha District periphery and western hill districts. It integrates with regional arteries that connect to the East-West Highway, the Tribhuvan Highway, and feeder roads toward Damauli, Mugling and Bhairahawa corridors.
The alignment runs from Shantinagar, Kathmandu through Naubise and follows the Trishuli River past Damauli, Tanahun District and Mugling before descending into Pokhara, Kaski District. The carriageway negotiates steep slopes, river terraces and engineered cuttings adjacent to the Mahabharat Range and skirts hills near Gandaki River tributaries. Major structural elements include bridges over the Trishuli River, retaining walls near Kavrepalanchok, and road embankments approaching the Seti River gorge. The highway corridor connects to junctions toward Narayanghat, Butwal, Bhaktapur and links onward to international transit routes to India via the Birgunj corridor.
Construction began under bilateral assistance during the 1970s with technical input from agencies that coordinated with the Department of Roads (Nepal), drawing on practices from projects such as the East-West Highway program and engineering models used in the Annapurna Conservation Area periphery. Early phases required negotiation with local administrations in Tanahun District, Lalitpur District and Kaski District and land acquisition processes involving councils in Kathmandu District. Periodic upgrades received funding and expertise analogous to projects supported by multilateral partners active in the region, reflecting post‑Rana era infrastructure priorities and national development plans overseen by ministries in Kathmandu.
The highway facilitated freight flows between the Kathmandu Valley and western markets such as Pokhara and Butwal, stimulating sectors including tourism to Annapurna Circuit, hospitality in Lakeside, Pokhara, agriculture in Tanahun terraced fields and trade through Narayanghat. Improved access led to urban expansion in towns like Mugling and influenced migration patterns to Kathmandu, reshaping service provision in Kaski and Lalitpur. The corridor underpins logistics for businesses supplying Tribhuvan International Airport and supports buses operated by companies serving routes to Damauli, Hetauda and western Nepal, while also affecting livelihoods of communities near Seti Zone and Gulmi hinterlands.
Steep gradients, monsoon-induced landslides near Naubise and sharp bends adjacent to the Trishuli have caused high accident rates involving intercity buses, freight trucks from Birgunj routes and private vehicles. Emergency responses engage units from Nepal Police, local District Administration Office teams and mountain rescue groups coordinated with hospitals such as those in Pokhara and Kathmandu. Maintenance cycles are managed by the Department of Roads (Nepal), with periodic resurfacing, slope stabilization projects and installation of guardrails influenced by design standards used on other corridors like the Tribhuvan Highway. Safety campaigns involve transport unions, municipal authorities in Pokhara Metropolitan City and provincial transport offices.
Key settlements and features along the alignment include Naubise, Mugling, Damauli, Bharatpur-adjacent junctions toward Chitwan National Park approaches, and terminus access to Pokhara Lakeside, the World Peace Pagoda (Pokhara), and viewpoints over the Annapurna Range and Machhapuchchhre. Cultural and religious sites near the corridor encompass temples and local shrines in Tanahun District markets and traditional settlements in Kaski District valleys. The highway also provides access to trekking trailheads that connect to the Annapurna Conservation Area Project and conservation areas managed by national agencies.
Traffic composition includes long-distance buses operated by private operators serving routes between Kathmandu and Pokhara, freight carriers linking Birgunj and Nepalgunj, and local minibuses serving commuters between municipal wards in Pokhara Metropolitan City and Hetauda. Tolling and revenue collection are overseen by road authorities with checkpoints at major junctions influenced by national transport regulations administered from Kathmandu. Intermodal transfers occur at hubs connecting to domestic air services at Pokhara Airport and road-rail freight connections transiting toward cross-border points of entry with India.
The corridor traverses seismic zones associated with the Himalayas and lies within areas susceptible to monsoon-triggered debris flows and slope failure in the Mahabharat Range. Construction and traffic pressure have prompted assessments of erosion impacts on riverine habitats including the Trishuli River and Seti River, and raised conservation considerations within the Annapurna Conservation Area. Mitigation measures have included slope stabilization, bioengineering, and catchment management coordinated with district conservation offices, while geological monitoring draws on expertise from institutions in Tribhuvan University, Kathmandu University and national geological surveys.
