Oakland Port in the US said it has completed a $432m, 12-year long dredging project to allow the facility to dock the world’s largest cargo ships.

The project involved dredging 12.8 million cubic yards of earth to deepen shipping channels to 50ft below sea level.

According to port officials, the port’s ability to handle bigger cargo ships is critical to its future.

Cargo shipments to the port declined almost 12.9% between January and August this year, compared to the same period in 2008.
