Rajasthan, the largest state of India by area, has a unique geographical position marked by arid regions, international borders, and diverse economic activities ranging from mining and agriculture to tourism and handicrafts. In such a setting, transport infrastructure plays a crucial role in shaping regional economic growth. This paper examines the impact of Rajasthan’s transport system—roads, railways, and airways—on its economic development using secondary data from government reports, economic surveys, and published studies. The analysis highlights how the expansion of highways, expressways, and dedicated freight corridors has improved market accessibility, encouraged industrial investments, boosted tourism inflows, and enhanced trade opportunities, particularly along major corridors like the Delhi–Mumbai Expressway. At the same time, regional disparities persist, as districts with weaker connectivity remain economically lagging. The paper also identifies challenges such as uneven distribution of infrastructure, maintenance gaps, and environmental concerns. Finally, it suggests policy directions for creating a more inclusive and sustainable transport-led growth model in the state.
