List of All National Highways in India
National Highways in India
National Highways play a crucial role in connecting various parts of India. The Ministry of Road Transport and Highways oversees the development and maintenance of these important roads. State Governments and Union Territories often propose new National Highways, which the Ministry reviews based on connectivity needs, priority, and budget availability.
Importance of National Highways
In India, National Highways form a vast network managed by the Ministry of Road Transport and Highways. The construction and upkeep of these highways are handled by various agencies, including the National Highway Authority of India (NHAI), the National Highways and Infrastructure Development Corporation (NHIDCL), and local public works departments (PWD) in states.
Roles of NHAI and NHDP
The NHAI is the key agency responsible for building, upgrading, and maintaining most of the National Highways. It works under the Ministry of Road Transport and Highways and plays a significant role in the National Highways Development Project (NHDP), aiming to enhance the highway network. The NHAI often relies on public–private partnerships (PPP) for the maintenance of highways and toll collection.

National Highways in India are at-grade roads, while Expressways are designed as controlled-access highways, allowing entrance and exit via special ramps. As of April 2019, India has a total of 142,126 km (88,313 mi) of National Highways. Although they make up just 2.7% of India’s total road network, they carry around 40% of the road traffic, according to 2013 statistics. In 2016, the government committed to doubling the highway length from 96,000 to 200,000 km.
