New Delhi, 29/9: The Indian government is expected to monetize close to Rs 1,99,290 crore ($24 billion) worth of highways over the next few years, a rating agency has said. With 4,000 kilometers to 4,500 kilometers (2,796.2 miles) of new roads likely to be commissioned annually by the National Highways Authority of India over the next three years, the government can monetize these assets through a Infrastructure Investment Trust or toll-operate-transfer model, CareEdge Ratings said in a note on Thursday.
