Roads in India are an important mode of transport in India. India has a network of over 6,331,791 kilometres (3,934,393 mi) of roads (as of 31 December 2022[update]). It is the second-largest road network in the world, after the United States.[2] At (1.94 km, 1.21 mi) of roads per square kilometre of land, the quantitative density of India's road network is equal to that of Hong Kong, and substantially higher than the United States (0.71 km, 0.44 mi), China (0.54 km, 0.34 mi), Brazil (0.23 km, 0.14 mi) and Russia (0.09 km, 0.056 mi).[3] Adjusted for its large population, India has approximately 5.13 kilometres (3.19 mi) of roads per 1,000 people, which is much lower than United States 20.5 kilometres (12.7 mi) but higher than that of China 3.6 kilometres (2.2 mi). India's road network carries over 71% of its freight and about 85% of passenger traffic.[4]
Since the 1990s, major efforts have been underway to modernize the country's road infrastructure.[5] As of 31 March 2020, 70.00% of Indian roads were paved. As of 31 December 2023, India had completed and placed into use over 35,000 kilometres (22,000 mi) of four or more lane highways connecting many of its major manufacturing, commercial and cultural centres.[3] According to the Ministry of Road Transport and Highways, as of March 2021, India had about 151,019 kilometres (93,839 mi) of national highways and expressways, plus another 186,528 kilometres (115,903 mi) of state highways. Major projects are being implemented under the Bharatmala, a Government of India initiative. Private builders and highway operators are also implementing major projects.[6][7]
