The government of India has approved a plan for constructing 1,000 kilometres of Expressways under NHDP Phase-VI at a cost of Rs 16,680 crore on the Design-Build-Finance-Operate-Transfer (DBFOT) model.

The main criteria for selection of Expressway corridors will be the traffic volume. The 400km Vadodara-Mumbai Corridor, which has the highest density, has been accorded top priority and considered for a feasibility study.
