The National Highways Authority of India (NHAI) was constituted by an act of Parliament, the National Highways Authority of India Act,1988. The authority is responsible for the development, maintenance and management of National Highways entrusted to it and for matters connected or incidental thereto. The Authority was operationalised in Feb, 1995. NHAI has been entrusted with National Highways Development Project (NHDP). Apart from this the authority is responsible to take up development, maintenance and management of National Highways across the country.
In order to monitor and manage National Highways, the authority has recently signed Memorandum of Understanding with National Remote Sensing Centre (NRSC) under Indian Space Research Organization (ISRO) and North East Centre for Technology Application and Research (NECTAR) for use of spatial technology. The satellite data and geospatial technology would be quite useful in providing vital inputs during the preparation of DPR, conducting pre-feasibility study, deciding new alignment, upgradation and road widening, monitoring of road segments which are under construction and keeping an eye on road assets.
