Baglung-Beu-Narethati Road Tunnel (7.5 km)

  • Project: Feasibility Study of Baglung-Beu-Narethati Road Tunnel (7.5 km)
  • Client: Department of Roads, Quality Research & Development Center (QRDC)
  • Location: Nepal
  • Date: Ongoing

Baglung-Beu-Narethathi Road Tunnel lies in Mid-hill in western Nepal in Baglung District. The construction of Baglung – Beu – Narethathi Road Tunnel effects directly and indirectly positive influence on Baglung, Pyuthan, Dolpa, Myadi ,Gulmi districts. It also helps in enhancing the tourism sector in these areas. The Road through Baglung, Beu continuously rises to hill ridge and continuously falls towards Hatiya has numerous turinings. The approximate entry point and exit coordinate of the proposed tunnel are 28°13’32.0S”N, 83°28’6.1 O”E and 28″1 6’6.27″N, 83°3 1’25.22″E. The construction of around 7.5 km road tunnel reduces the tentative length of the road upto 18 Km and hence reduces the travel time making the travel safe in geographically steep terrain. The construction of road tunnel helps in enhancing the economic growth in these areas. 

Road tunnels are feasible alternatives to cross a water body or traverse through physical barriers such as mountains, existing roadways, railroads, or facilities; or to satisfy environmental or ecological requirements. In addition, road tunnels are viable means to minimize potential environmental impact such as traffic congestion, pedestrian movement, air quality, noise pollution, or visual intrusion; to protect areas of special cultural or historical value such as conservation of districts, buildings or private properties; or for other sustainability reasons such as to avoid the impact on natural habit or reduce disturbance to surface land.

The main objective of the study is to prepare a comprehensive feasibility study report of road tunnel to be constructed under design built or EPC contract model:
