The Muglin to Narayanghat road provides an important connection as it links the Prithvi Highway with the East-West Highway. Nepal’s Roads Department intends to optimise the building process by using prefabricated steel and concrete bridge deck components that will be placed on top of pillars erected onsite. The World Bank will provide funding to construct 14 of the bridges required. The Muglin to Narayanghat road passes through widely varying terrain, with much of the route following the path of the Trishuli River. At its southern end the road runs through a flood plain area that is comparatively well-populated and is used extensively for agriculture. The northern end of the road however is in a mountainous area and poses rather different challenges to construction.
