The National highways in India are a network of trunk 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 intersection of highways flyovers are provided to bypass the city/town/village traffic and these highways are designed for speed of 100 km/hr. Some national highways have interchanges in between, but do not have total controlled-access throughout the highways. It is 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.

The National Highways Development Project (NHDP) is 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.

Some roads are not access-controlled expressways, but are still named as expressways, such as the Biju Expressway, these are actually state highways which are not declared by central government as an Expressway, hence not an Expressway or National Highway.
