Step 1: Study the map:
The map shows a ship canal (thick black line) running from the Mediterranean coast in the north, past El Kantera, Ismailiya and the Great Bitter Lake, to the Red Sea in the south.
The labels Delta of the Nile, Ismailiya, Great Bitter Lake and Little Bitter Lake are all places along this canal in Egypt.
Step 2: Recall the facts:
A man-made sea-level canal in Egypt joins the Mediterranean Sea and the Red Sea. It was opened in 1869.
It saves a long voyage around Africa for ships between Europe and Asia.
Final Answer:
The waterway shown on the map is the Suez Canal.
