Shipping Canals

The Suez and Panama Canals are the two most important man-made navigation waterways in the world. They are not just shortcuts for ships; they function as gateways of commerce, connecting the eastern and western hemispheres and reshaping global trade routes.

The Suez Canal

Constructed in 1869 in Egypt, the Suez Canal links the Mediterranean Sea with the Red Sea. It runs from Port Said in the north to Port Suez in the south. Its primary effect was to give Europe a new, direct gateway to the Indian Ocean. For example, the sea-route distance between Liverpool and Colombo is drastically reduced compared to the older route around the Cape of Good Hope.

The canal is a sea-level canal — it has no locks. It is about 160 km long and 11 to 15 metres deep. Around 100 ships travel through it daily, and each ship takes 10–12 hours to complete the crossing. The tolls charged are so heavy that some shipping companies find it cheaper to take the longer Cape Route if the time delay is not a concern.

A railway line follows the canal to Suez, and from Ismailia there is a branch line to Cairo. A navigable fresh-water canal from the Nile also joins the Suez Canal at Ismailia, supplying fresh water to Port Said and Suez.

The Panama Canal

The Panama Canal connects the Atlantic Ocean in the east to the Pacific Ocean in the west. It was constructed across the Panama Isthmus, between Panama City and Colon, by the United States government. The U.S. purchased an 8 km wide strip of land on either side of the canal and named it the Canal Zone.

The canal is about 72 km long and involves a very deep cutting for a length of 12 km. Unlike the Suez, it has a six-lock system. Ships cross different levels — rising and falling 26 metres — through these locks before entering the Gulf of Panama. …
