The National Highways Authority of India (NHAI) is an autonomous agency of the Government of India, responsible for management of a network of over 70,000 km of National Highways in India.[3] It is a nodal agency of the Ministry of Road Transport and Highways. The first chairman of NHAI was Mr Yogendra Narain, IAS and its current chairman is Raghav Chandra, IAS.[4]


The NHAI was created through the promulgation of the National Highways Authority of India Act, 1988. In February 1995, the Authority was formally made an autonomous body.[1]
It is responsible for the development, maintenance, management and operation of National Highways, totaling over 92,851.05 km (57,694.97 mi) in length.[5]

The NHAI is also responsible of the toll collection on several highways.[6]

The NHAI has the mandate to implement the National Highways Development Project (NHDP). The NHDP is under implementation in Phases.[5]

  • Phase I: Approved in December 2000, at an estimated cost of INR 300 Billion, it included the Golden Quadrilateral (GQ), portions of the NS-EW Corridors, and connectivity of major ports to National Highways.
  • Phase II: Approved in December 2003, at an estimated cost of INR 343 Billion, it included the completion of the NS-EW corridors and another 486 km (302 mi) of highways.
  • Phase IIIA: This phase was approved in March 2005, at an estimated cost of INR 222 Billion, it includes an upgrade to 4-lanes of 4,035 km (2,507 mi)of National Highways.
  • Phase IIIB: This was approved in April 2006, at an estimated cost of INR 543 Billion, it includes an upgrade to 4-lanes of 8,074 km (5,017 mi) of National Highways.
  • Phase V: Approved in October 2006, it includes upgrades to 6-lanes for 6,500 km (4,000 mi), of which 5,700 km (3,500 mi) is on the GQ. This phase is entirely on a DBFO basis.
  • Phase VI: This phase, approved in November 2006, will develop 1,000 km (620 mi) of expressways at an estimated cost of INR 167 Billion.
  • Phase VII: This phase, approved in December 2007, will develop ring-roads, bypasses and flyovers to avoid traffic bottlenecks on selected stretches at a cost of INR 167 Billion.

The progress of the NHDP can be tracked from the NHAI official website, which updates maps on regular basis.

NHAI helps in implementing Special Accelerated Road Development Programme for North Eastern Region (SARDP-NE); a project to upgrade National Highways connecting state capitals to 2 lane or 4 lane in north eastern region.[8]

NHAI is planning to sign a memorandum of understanding (MoU) with the Indian Space Research Organisation (Isro) for adoption of best technologies in the road sector.[5]


A 2012 report prepared by the World Bank’s Institutional Integrity Unit alleged that fraudulent and corrupt practices were being followed by Indian contractors working on national highway projects funded by it, and sought a thorough investigation into the matter.[9] The report also alleged that contractors paid bribes and gifts, including gold coins, to “influence the actions” of officials and consultants of the National Highways Authority of India.[9]
