NHAI will convert about 15,000 km of roads from two-lanes to four-lanes for enhancing the economic efficiency of the highways. "We are looking at economically efficient corridors and have identified around 15,000 km of roads, which we will convert from two-lanes to fourlanes, to increase their economic efficiencies by connecting points that have been left out historically," NHAI chairman Raghav Chandra said.
