Our objective is to ensure that all contract awards and procurements conform to the best industry practices with regard to transparency of process, adoption of bid criteria to ensure healthy competition in award of contracts, implementation of projects conform to best quality requirements and the highway system is maintained to ensure best user comfort and convenience.

The National Highways have a total length of 1,32,499 (approx) km to serve as the arterial network of the country. Although National Highways constitute only about 2 per cent of the road network, it carries 40 per cent of the total road traffic. Rapid expansion of passenger and freight traffic makes it imperative to improve the road network in the country. Accordingly, Government of India launched major initiatives to upgrade and strengthen National Highways through various phases of National Highways Development Project (NHDP).
