National Highway Authority of India (NHAI) on Tuesday said it aims at awarding contracts worth Rs 25,000 crore for 270 km road projects in West Bengal during the current fiscal. In a bid to reduce congestion from Vidyasagar Setu in the state, it has decided to construct a 6.5-km six-lane elevated road on the existing four-lane Kona Expressway at a cost of Rs 2,000 crore and will float a tender for the project by December this year, an official said.
