Rs 3,500 crore boost for Chennai: Inside the upgraded double-decker port corridor plan

Construction of the 20.9 km elevated corridor is moving at full speed, forming a key infrastructure link between Chennai Port and Maduravoyal, aimed at improving freight and city traffic movement efficiency.

The project has been upgraded into a double-tier structure with major design changes, significantly increasing capacity and allowing separation of heavy freight traffic from local urban vehicular movement.

The upper level is designed exclusively for container trucks and port-bound freight vehicles, ensuring uninterrupted cargo flow directly between industrial zones and Chennai Port without city traffic disruption.

The lower tier supports urban traffic with 13 entry and exit ramps at key locations, improving connectivity across Chennai and easing congestion along major city routes near the Cooum river corridor.

Once completed, the corridor is expected to significantly improve logistics efficiency and increase Chennai Port’s cargo handling capacity from 53 MTPA to nearly 200 MTPA by 2047, strengthening trade connectivity.
