Physical Infrastructure
Physical infrastructure, which includes roads, railways, ports and airports, is the skeleton of the economy. It determines how quickly goods and people move, how competitive exports are, and how evenly development spreads. India has launched a series of major programmes to modernise this infrastructure, and questions on highways, ports, railway corridors and aviation schemes appear regularly in competitive examinations. These notes bring together the flagship road and port programmes, the main facts about Indian Railways, the regional connectivity scheme for aviation, and the institutions that finance and coordinate infrastructure investment.
Roads and highways
Bharatmala Pariyojana is a flagship umbrella programme of the Ministry of Road Transport and Highways for developing national highways, economic corridors, border roads and expressways; it was launched in 2017, with Phase I approved by the Union Cabinet in October 2017. The Golden Quadrilateral is a national highway network connecting the four metropolitan cities of Delhi, Mumbai, Chennai and Kolkata, taken up under the National Highways Development Project. The National Highways Authority of India, established in 1988 under the National Highways Authority of India Act, implements the project. NH-44, running from Srinagar to Kanyakumari over about three thousand seven hundred and forty-five kilometres, is the longest national highway in the country.
Ports and coastal development
Sagarmala is a port-led development programme aimed at modernising ports and promoting coastal economic development, and it operates under the Ministry of Ports, Shipping and Waterways; it was approved and launched in 2015. Jawaharlal Nehru Port, also known as Nhava Sheva and located near Mumbai, is the largest container-handling port of India. Kolkata Port, commissioned in 1870, is the oldest major port, while Mumbai Port is the largest natural harbour and Visakhapatnam is the deepest land-locked port. Chennai Port is the oldest artificial harbour. Kandla Port, now called Deendayal Port, was developed after independence to handle the traffic that earlier passed through Karachi. India now has fourteen major ports, comprising the twelve traditional major ports plus Vadhvan Port and Galathea Bay Port added in 2024, and all of them are administered by the Ministry of Ports, Shipping and Waterways.
Railways and freight corridors
Indian Railways is one of the largest railway networks in the world. Dedicated Freight Corridors are exclusive high-capacity railway lines meant only for freight traffic, and they are being built by the Dedicated Freight Corridor Corporation of India Limited. The two sanctioned corridors are the Eastern Dedicated Freight Corridor from Ludhiana to Dankuni and the Western Dedicated Freight Corridor from Jawaharlal Nehru Port to Dadri. Indian Railways historically used three gauges: broad gauge of one thousand six hundred and seventy-six millimetres, metre gauge of one thousand millimetres and narrow gauge of seven hundred and sixty-two or six hundred and ten millimetres. The first passenger train ran on 16 April 1853 from Bori Bunder in Bombay to Thane, a distance of about thirty-four kilometres. The Central Railway has its headquarters in Mumbai, and the South Coast Railway, with its headquarters at Visakhapatnam, is the newest railway zone, created in 2019.
Civil aviation and urban transport
UDAN, which stands for Ude Desh ka Aam Nagrik, is the Regional Connectivity Scheme launched in 2017 to make air travel affordable for the common citizen by connecting unserved and underserved airports. It is implemented by the Ministry of Civil Aviation, in coordination with the Airports Authority of India and the airlines. The Airports Authority of India was constituted on 1 April 1995 by merging the International Airports Authority of India and the National Airports Authority. Cochin International Airport was the first Indian airport built under the public-private partnership model, becoming operational in 1999. In urban transport, the Kolkata Metro, which started operations in 1984, was the first metro rail system in India and also the first underground metro.
Financing and coordination of infrastructure
The National Infrastructure Pipeline is a flagship initiative announced in 2019 to provide world-class infrastructure, with a projected investment of about one hundred and eleven lakh crore rupees during the period from 2020 to 2025. It is coordinated by the Department of Economic Affairs under the Ministry of Finance, and energy, roads, urban infrastructure and railways are among the sectors that dominate investment under it. The National Investment and Infrastructure Fund is India's quasi-sovereign wealth fund created for financing infrastructure projects, and it was established in 2015, having been announced in the Union Budget of 2015-16. The India Infrastructure Finance Company Limited provides long-term debt financing for infrastructure projects along with the fund and other financial institutions.
