As per the policy initiatives of the Indian government regarding industrial corridors, the Amritsar – Kolkata, Delhi – Mumbai, and Chennai – Bengaluru corridors are designated as major industrial corridors aimed at facilitating industrial development and connectivity. The Kolkata – Guwahati route, while important for connectivity, is not typically listed as one of the established major industrial corridors in the same context as the others.
Identifying the officially recognized and planned industrial corridors in India is crucial for understanding the country’s infrastructure and industrial development strategy.
Major industrial corridors in India include the Delhi-Mumbai Industrial Corridor (DMIC), Amritsar-Kolkata Industrial Corridor (AKIC), Chennai-Bengaluru Industrial Corridor (CBIC), East Coast Economic Corridor (ECEC) which includes the Vizag-Chennai Industrial Corridor, and the Bengaluru-Mumbai Economic Corridor (BMEC). These corridors leverage dedicated freight corridors and highways to create manufacturing hubs and smart cities.
