The Golden Quadrilateral is a national highway network connecting several major industrial, agricultural and cultural centres of India. It forms a quadrilateral with all the four major metro cities of India forming the vertices, viz., Delhi (north), Kolkata (east), Mumbai (west) and Chennai (south). Other major cities connected by this network include Ahmedabad, Bengaluru, Balasore, Bhadrak, Bhubaneswar, Cuttack, Berhampur, Durgapur, Faridabad, Guntur, Gurugram, Jaipur, Kanpur, Pune, Kolhapur, Surat, Vijayawada, Eluru, Ajmer, Visakhapatnam, Bodhgaya, Varanasi, Prayagraj, Agra, Mathura, Dhanbad, Gandhinagar, Udaipur, and Vadodara. The main objective of these super highways is to reduce the travel time between the major cities of India, running roughly along the perimeter of the country. The North–South corridor linking Srinagar and Kanyakumari, and East–West corridor linking Silchar (Assam) and Porbandar (Gujarat) are additional projects. These highway projects are implemented by the National Highway Authority Of India (NHAI). At 5,846 kilometres (3,633 mi), it is the largest highway project in India and the fifth longest in the world. It is the first phase of the National Highways Development Project (NHDP), and consists of two, four, and six-lane express highways, built at a cost of ₹600 billion (US$7.2 billion). The project was planned in 1999, launched in 2001, and was completed in 7 January 2012.
The national highways in India are a network of limited access roads owned by the Ministry of Road Transport and Highways. National highways have flyover access or some controlled-access, where entrance and exit is through the side of the flyover. At each highway intersection, flyovers are provided to bypass the traffic on the city, town, or village. These highways are designed for speeds of 100 km/h. Some national highways have interchanges in between, but do not have total controlled-access throughout the highways. The highways are constructed and managed by the Central Public Works Department (CPWD), the National Highways and Infrastructure Development Corporation Limited (NHIDCL), and the public works departments (PWD) of state governments. Currently, the longest national highway in India is National Highway 44 at 4,112 km. India started four laning of major national highways with the National Highway Development Project (NHDP). As of March 2022 India has approximately 35,000 km of four laned National highways.
The National Highways Authority of India or NHAI is an autonomous agency of the Government of India, set up in 1995 and is responsible for management of a road network of over 50,000 km of National highways out of 1,32,499 km in India. It is a nodal agency of the Ministry of Road Transport and Highways (MoRTH). NHAI has signed a memorandum of understanding (MoU) with the Indian Space Research Organisation (ISRO) for satellite mapping of highways.
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. This is the second-largest road network in the world, after the United States. At 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, China, Brazil and Russia. 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.
The National Highways Development Project (NHDP) was a project of four laning of existing national highways and six laning of selected major national highways of India. The project was started in 1998 under the leadership of Prime Minister, Atal Bihari Vajpayee. National Highways account for only about 2% of the total length of roads, but carry about 40% of the total traffic across the length and breadth of the country. This project is managed by the National Highways Authority of India (NHAI) under the Ministry of Road, Transport and Highways. The NHDP represents 49,260 km of roads and highways work and construction in order to boost economic development of the country. The government has planned to end the NHDP program in early 2018 and subsume the ongoing projects under a larger Bharatmala project.

Expressways are the highest class of roads in India. In July 2023, the total length of expressways in India was 5,930 km (3,680 mi), with 11,127.69 km (6,914.43 mi) under construction. These are controlled-access highways where entrance and exits are controlled by the use of cloverleaf, three-way, trumpet or grade separated interchanges that are incorporated into the design of the expressway and designed for maximum speed of 120 km/h, whereas National highways are flyover access or tolled, where entrance and exit is through the side of the flyover, at each intersection of highway with road, flyovers are provided to bypass the city/town/village traffic and these highways are designed for speed of 100 km/h. Some roads are not access-controlled expressways but are still named expressways, such as the Bagodara–Tarapur Expressway, Biju Expressway, these are actually state highways that are not declared by the central government as an Expressway, hence not an Expressway or National Highway.
