The National Highways Development Project (NHDP) is an initiative by the Government of India aimed at improving and expanding the national highway network. Launched in 2001, the project focuses on upgrading existing highways and constructing new ones to enhance connectivity across the country. It plays a crucial role in facilitating trade, reducing travel time, and promoting economic growth. The NHDP is divided into several phases, each targeting specific stretches of highways for development. Key features include the construction of expressways, four-lane highways, and road safety measures. The project is essential for supporting India's growing transportation needs and improving infrastructure.
