The National Highways Development Project (NHDP) is a project to upgrade, rehabilitate and widen major highways in India to a higher standard. The project was started in 1998 under the leadership of Prime Minister, Atal Bihari Vajpayee.

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 consume the ongoing projects under a larger Bharatmala project.
