Highway development in India got a kickstart in 1995 with the setting up of the National Highways Authority of India (NHAI). The organization has a mandate to implement the National Highways Development Project (NHDP), which is the largest highway project in India’s history whose objective is to develop world class roads that provide uninterrupted traffic flow throughout the country.
According to the organization’s website, the “NHDP (Phase I & II) was launched in 1999 covering a length of nearly 14,000 km at an estimated cost of Rs. 54,000 crore (at 1999 prices) (USD 12.317 billion) and NHDP (Phase III) was launched in 2005 for upgradation and 4 laning of 10,000 km of selected high-density corridors of National Highways at an estimated cost of Rs. 55,000 crore (at 2005 prices) (USD 12.544 billion).”
The foundation of the highway development program was laid with the announcement of several projects to develop the Golden Quadrilateral – a world class set of highways connecting Delhi, Mumbai (previously known as Bombay), Chennai (previously known as Madras) and Kolkata (previously known as Calcutta).
