And the Government can hardly afford to chase away investment. The requirement for the next 20 years—to be met by the BOT pro-gramme—has been estimated to be 13,000 km of SNHs, equivalent to western high-speed freeways. "The average cost of construction of each kilometre is about Rs 8 crore, including the land acquisition cost estimated to be Rs 1.5 crore perkm," says Yogendra Narain, chairman, National Highways Authority of India (NHAI). "The total investment required for building these highways, coupled with maintenance of the existing national highways, is about Rs 150,000 crore, over the next 20 years. This translates into about Rs 7,500 crore per year and the money allocated by the Government for national highways is about one-tenth of this (Rs 700 crore for 1995-96). It is not enough even for maintenance," he adds.
