Some noteworthy achievements and challenges have marked the journey of road development in Nepal since the inception of the first road project in 1924. As of 2022, Nepal has made substantial progress, boasting a road network spanning 74,756 km, with ambitious plans to add 33,000 km of national/provincial highways by 2043. However, impediments like the absence of integrated transport planning and inter-agency coordination necessitate attention. The government is proactively addressing these challenges by implementing policies for balanced, safe, sustainable, and environmentally friendly road infrastructure. The study underscores the pivotal role of engineering geomorphology and geotechnical studies in overcoming geological challenges, particularly Deep-seated Gravitational Slope Deformations (DGSDs). Examining the Mugling-Pokhara Road upgrading project as a case study reveals complexities and emphasizes the importance of continuous assessments for adaptive strategies. The road development endeavors in Nepal require a delicate balance between progress and challenges, emphasizing the need for stakeholders to embrace innovative solutions to navigate the unique geological and climatic conditions of the Himalayan region. The study concludes that while geotechnic in Nepalese roads is no longer a myth, successful implementation demands a strong commitment from the government and development partners.
