The project will carry out a road safety survey to identify critical accident spots across the state highways and carry out measures to improve these, it said.

Total cost of the project is USD 655 million. Of this, the state government will provide USD 202 million and the private sector will invest an estimated USD 107 million through hybrid annuity contracts.
