摘要：Road construction in Himalaya is always challenging job. Himalaya is young mountain belt and tectonically active. National Highway-44 passes through mountain with varying topography and geological strata from Outer Himalaya to Central Himalaya. Not only geological and geomorphological structures but varying and critical climatic conditions have to tackled during the construction. Climatically area belongs to humid sub-tropical region of Jammu to temperate region of Banihal. Major geological challenges are Landslide, Hill slope, crossing of fault zones, tunnel construction and Hydro meteorological disaster. In this paper, I will discuss about the main geological challenges facing by road widening construction companies and will suggest precautionary measures for construction feasibilities.
