At the Rising Bihar Investor Summit 2026, Gadkari said the expanding road network would strengthen connectivity and help attract investment, industry and jobs.
He said the Patna–Purnea Greenfield Expressway proposal has been sent for Cabinet approval, and that a planned ring road will improve connectivity to Darbhanga airport. One proposed 526-km corridor would run about 410 km through Bihar, with roughly ₹52,000 crore to be invested in the state.
