Road Corridor Environment Improvement Study of Prithivi Rajmarg (Naubise-Mugling)
The Prithivi Rajmarg originates at Naubise in Dhading district and ends at Prithivi Chowk Pokhara of Kaski district. This road is classified as National Highway 9H04) and is part of Asian Highway as well. The length of road section under study is about 83.1 km from Naubise to Mugling and passes through Dhading and Chitwan Districts. This road has been constructed as a double lane national highway with assistance from Government of People’s Republic of China in 1978. The sector of road under study starts at an altitude of 940 m at Naubise and follows left bank of Naubise Khola, Mahesh Khola, Trishuli River and reaches Trishuli Bridge, near Mugling at an altitude of 260m.
Road Corridor Environment Improvement Study of Birgunj-Kalaiya Road
The Birgunj-Kalaiya originates at dry port/Kalaiya Chowk of Tribhuwan Rajpath (4.23 Km north from Birgunj city center) in Parsa District and ends at Kalaiya in Bara districts. The road under study is about 11.66 km, 2.78 Km up to Gandak Canal lies in Parsa and remaining 8.88 Km lies in Bara district. This road has been constructed as Padma Road and is a single lane black top Feeder Road standard. The present traffic on the road is about 1000 vehicles per day. Whole sector of road under study lies in Terai region.
The main objective of this study is to conduct a geological/geotechnical, bioengineering and social survey of the road corridors; Roadside investigation concentrating mainly along the road corridor but if required down to the slope up to the river and above the road corridor to the nearest ridge or stable slope; Identify and survey the existing landslides and potential landslide hazards with focus on source and factors contributing to the increase of landslide hazard within the road corridor; mapping of landslide hazard in the Topographical map of scale not smaller than 1:25,000; design of bioengineering structure to protect the unstable slope based on the site parameters and social survey of the road corridor’s settlement focusing on socio-environmental aspects.
