The National Highways Authority of India (NHAI) is an autonomous body under the Ministry of Road Transport & Highways. It is responsible for the development, maintenance, and management of national highways entrusted to it by the Government of India. The network it handles spans over 92,000 km of national highways—critical infrastructure driving India's connectivity and economic growth.
NHAI was established under the National Highways Authority of India Act, 1988, and began operations in February 1995. It operates under the Ministry of Road Transport & Highways, with ownership and oversight administered by the Government of India.
NHAI's structure comprises a robust three-tier system: Headquarters located in New Delhi, Regional Offices spread across various states, and localized Project Implementation Units (PIUs) managed directly by experienced Project Directors.
A 21.65 km, six-lane elevated expressway in Haryana, fully opened in July 2022. Total project cost: ₹1,466 crore.
A 6.8 km bypass in Kerala, part of NH-66, running along the scenic beach. Jointly built by central and state governments; inaugurated in 2021.
A newly completed expressway link featuring efficient slip lanes and cloverleaf ramps to streamline heavy traffic flow between Delhi and Jaipur.
Includes flyovers, underpasses, and escalator-equipped foot overbridges along NH-27. Designed to modernize pedestrian safety and traffic management.
NHAI excels in executing large-scale infrastructure projects across demanding geographical terrains. It has pioneered rapid construction benchmarks (such as building 75 km in 5 days for a Guinness World Record). Furthermore, it champions environmental sustainability through its Green Highways Policy, fostering long-term ecological and social stewardship.
