National Highways Authority of India (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 four-lanes, to increase their economic efficiencies by connecting points that have been left out historically," NHAI Chairman Raghav Chandra said at a road conference organised by Assocham.
