Abstract: Highways are instrumental in shaping patterns of land use, particularly in regions undergoing rapid urbanization and economic transformation. This dissertation investigates the long-term impact of operational highways on land use changes, with a focus on urban expansion, the transformation of peri-urban areas, and the development of residential, commercial, and industrial infrastructure. Unlike studies that emphasize highway construction or short-term effects, this research centers on highways that have been functional for at least two decades, providing a comprehensive view of their lasting influence.

Through a detailed literature review, policy analysis, and two case studies—National Highway-48 in the National Capital Region of India and the Antalya–Alanya Highway in Turkey—the study reveals that highways significantly contribute to land conversion, particularly the shift from agricultural to urban and industrial uses. These transformations are accompanied by environmental challenges, such as biodiversity loss, soil degradation, and increased pollution, along with socio-economic implications including population relocation, infrastructure pressure, and livelihood disruptions.

The findings underscore the necessity for integrated land use planning and environmental assessments that consider the full spectrum of impacts induced by highways. By adopting sustainable development frameworks, incorporating stakeholder participation, and enhancing regulatory mechanisms, highway-induced land use changes can be better managed to support both economic growth and ecological balance.
