Length of National Highways in India from 2005 to 2024, by State

The most striking observation is the dramatic overall growth in India’s national highway network, which has more than doubled from approximately 65,569 kilometres in 2005 to 146,145 kilometres by 2024. This represents a 123% increase in highway infrastructure, demonstrating India’s substantial commitment to improving its transportation network. Maharashtra stands out as the state with the most extensive national highway network in 2024, with 18,459 kilometres, followed by Uttar Pradesh (12,292 km) and Rajasthan (10,706 km). This aligns with the economic and geographical significance of these states, with Maharashtra being an industrial powerhouse, Uttar Pradesh being India’s most populous state, and Rajasthan covering vast geographical territory. The data reveals distinct phases of highway development. While the period from 2005-2010 saw relatively modest growth (about 5,365 km added), the pace accelerated significantly after 2013. The most dramatic expansion occurred between 2016-2017, when approximately 19,482 kilometers were added in a single year—representing nearly 20% of the total 2016 network length. Several states experienced transformative growth in their highway networks. Maharashtra’s highways increased more than fourfold, from 4,176 km in 2005 to 18,459 km by 2024. Similarly, Arunachal Pradesh saw its network expand nearly elevenfold, from 392 km to 4,285 km, highlighting increased focus on connectivity in northeastern states. The creation of Telangana state is also reflected in the data, with figures first appearing around 2015 and growing steadily to 4,926 km by 2024, demonstrating infrastructure development priorities in newly formed states. The data suggests strategic prioritisation of highway development across different regions, potentially reflecting economic development goals, population density considerations, and efforts to improve connectivity in previously underserved areas. This two-decade expansion of India’s national highway network represents a significant infrastructure achievement that has likely improved transportation efficiency, economic connectivity, and regional development across the country.
