The National Highways Network of India measures over 70,934 km as of 2010, including over 1,000 km of limited-access expressways. Out of 71,000 km of National Highways 15,000 plus km are 4 or 6 lanes and remaining 50,000 km are 2 lanes. The National Highways Authority of India (NHAI) is the nodal agency responsible for building upgrading and maintaining most of the national highways network. The national Highways Development Project (NHDP) is a major effort to expand and upgrade the network of highways. NHAI often uses a public-private partnership model for highway development, maintenance and toll collection. National highways constituted about 2% of all the roads in India, but carried about 40% of the total road traffic as of 2010. The majority of existing national highways are two-lane roads (one lane in each direction), though much of this is being expanded to four-lanes, and some to six or eight lanes. Some sections of the network are toll roads. Over 30,000 km of new highways are planned or under construction as par of the NHDP as of 2011. This includes over 2,600 km of expressways currently under construction. 

What is the current measurement of expressways under construction in India ?

Violence has played a great part in the would's history. It  is today playing an equally important part and probably it will continue to do so for a considerable time. It is impossible to ignore the importance of violence in the past and present. To do so is to ignore life. Yet violence is undoubtedly bad and brings an unending trail of evil consequences with it. And worse even than violence are the motives of hatred, cruelty, revenge and punishment which very often accompany violence. Indeed violence is bad, not intrinsically, but because of these motives that go with it. There can be violence without these movies there can be violence of  a good object as well as for an evil object. But it is extremely difficult to separate violence from these motives, and therefore, it is desirable to avoid violence as far as possible. In avoiding it, however someone can not accept a negative attitude of submitting to bad and far greater evils. Submission to violence or the acceptance of an unjust regime based on violence is against the spirit of non-violence. The non-violent method, in order to justify itself, must be dynamic and capable of changing such a regime of social order.
