Model Answer

Mumbai is the biggest port with a spacious natural harbour, but heavy traffic led to congestion. Jawaharlal Nehru Port was planned specifically to decongest the Mumbai port. It was not built as a replacement but as a complementary facility to share the load of cargo handled by Mumbai.

Beyond relieving congestion, Jawaharlal Nehru Port now serves as a hub port for the entire region, meaning it handles and redistributes cargo for multiple destinations. This dual role — decongesting Mumbai while acting as a regional hub — makes it a complement rather than a competitor to Mumbai port.
