West Bengal's (WB) proposed state highways authority will work to attract private investment in road infrastructure development, State Finance Minister Amit Mitra has said. The state government has proposed to create infrastructure through the PPP model. The decision to set up a highways authority similar to the National Highways Authority of India (NHAI) is a step toward achieving goals in the road sector.At present, the Public Works Department controls and maintains highways in the state. The state highway authority is likely to take over this role once it comes into place. West Bengal has a total road network covering 92,023 km, of which National Highways comprise 2,578 km and state highways cover 2,393 km.
