The construction of the highway started in 1967 with the help of the Chinese government. The construction was completed in 1974. The highway is named after King Prithvi Narayan Shah.
This landslide-prone and heavily congested highway passes through five districts: Kathmandu, Dhading, Chitwan, Tanahu and Kaski. This highway has a junction with Tribhuvan Highway at Naubise. The Baratpur-Mugling section connects this highway to Mahendra Highway, the longest highway in Nepal. Until 2011 opening of the B.P. Koirala Highway, this highway was the only improved land route from Kathmandu Valley to all points south, and as such the main artery for heavy trucks into Kathmandu Valley and into Pokhara.
The hills that flank the 206 km (128 mi) stretch of the Prithvi Highway from Kathmandu to Pokhara contain some of the most important religious sites in Nepal. Manakamana Mandir near Mugling, is one of the oldest temples in central Nepal and is an important destination for Hindu pilgrimage.
A 25 km (16 mi) road off the main highway connecting Pokhara and Kathmandu links to historical town of Gorkha. Apart from these historic points of interest, the highway is lined with modern townships that have sprung up around important road junctions and river crossings. The scenery along the highway is dramatic as it follows a series of deep river valleys. On clear days, most of the way to Pokhara there are views of Machapuchare and the Annapurna massif.
The 370-metre (1,210 ft) bridge over the Madi River at Damauli may collapse due to weakened foundation, as it was constructed at the same time as the highway with Chinese assistance. Sand and rock extraction nearby have weakened the pillars on a crucial bridge of Nepal's busiest highway.
The Krishna Bheer (Nepali: कृष्ण भीर) is a cliff located in Dhading District by the side of Prithivi Highway. It is the most landslide prone part of the highway. The steep elevation of the cliff compounded with the loose mud constituent of the cliff creates the vulnarability of landslide in monsoons. Recently, a team of Nepalese bio-engineers have managed to prevent the landslide over a season which is considered as an achievement in modern Nepalese engineering.
