What is the Suez Canal?

The Suez Canal is a human-made waterway that cuts north-south across the Isthmus of Suez in Egypt. The Suez Canal connects the Mediterranean Sea to the Red Sea, making it the shortest maritime route to Asia from Europe. Since its completion in 1869, it has become one of the world’s most heavily used shipping lanes.

Why is the Suez Canal important?

The Suez Canal is important because it is the shortest maritime route from Europe to Asia. Prior to its construction, ships headed toward Asia had to embark on an arduous journey around the Cape of Good Hope at the southern tip of Africa. Because of its strategic location, the canal is both heavily used and heavily protected.

How has the Suez Canal changed throughout history?

Various forms of what is today the Suez Canal existed in Egypt between 1850 BCE and 775 CE, although primarily to facilitate trade between the Nile River Delta and the Red Sea. Between 1859 and 1869, Egyptian khedive Saʿīd Pasha partnered with France’s Suez Canal Company to build the present canal connecting the Mediterranean and Red seas.

How was the Suez Canal’s construction paid for?

The Suez Canal was financed by the Suez Canal Company, a joint-stock company headquartered in Paris. At the time of its founding, France had 52 percent of shares and Egypt held 44 percent. By 1875, Egypt’s shares had been sold to Great Britain, which assisted in the canal’s administration.

What is the international status of the Suez Canal?

The Suez Canal’s international status has a murky history. Per the 1888 Convention of Constantinople, the canal is open to ships of all nations in peacetime and wartime. However, there have been numerous instances of ships being denied passage in wartime, especially during World War I and World War II. Because of tensions with Israel, Egypt closed the canal during the Suez Crisis of 1956–57 and the Arab-Israeli War of 1967.

How many ships use the Suez Canal?

In 2023 there were 26,434 transits of the Suez Canal, according to the Suez Canal Authority. That number dropped to 13,213 in 2024. Tankers made the largest percentage of transits in 2023 (about 32 percent) and 2024 (about 37 percent).

Suez Canal, sea-level waterway running north-south across the Isthmus of Suez in Egypt to connect the Mediterranean and the Red seas. The canal separates the African continent from Asia, and it provides the shortest maritime route between Europe and the lands lying around the Indian and western Pacific oceans. It is one of the world’s most heavily used shipping lanes. The canal extends 193 km (120 miles) between Port Said (Būr Saʿīd) in the north and Suez in the south, with dredged approach channels north of Port Said, into the Mediterranean, and south of Suez. The canal does not take the shortest route across the isthmus, which is only 121 km (75 miles). Instead, it utilizes several lakes: from north to south, Lake Manzala (Buḥayrat al-Manzilah), Lake Timsah (Buḥayrat al-Timsāḥ), and the Bitter Lakes—Great Bitter Lake (Al-Buḥayrah al-Murrah al-Kubrā) and Little Bitter Lake (Al-Buḥayrah al-Murrah al-Ṣughrā). The Suez Canal is an open cut, without locks, and, though extensive straight lengths occur, there are eight major bends. To the west of the canal is the low-lying delta of the Nile River, and to the east is the higher, rugged, and arid Sinai Peninsula. Prior to construction of the canal (completed in 1869), the only important settlement was Suez, which in 1859 had 3,000 to 4,000 inhabitants. The rest of the towns along its banks have grown up since, with the possible exception of Al-Qanṭarah.

Physical features

Geology

The Isthmus of Suez, the sole land bridge between the continents of Africa and Asia, is of relatively recent geologic origin. Both continents once formed a single large continental mass, but during the Paleogene and Neogene periods (about 66 to 2.6 million years ago) the great fault structures of the Red Sea and Gulf of Aqaba developed, with the opening and subsequent drowning of the Red Sea trough as far as the Gulf of Suez and the Gulf of Aqaba. In the succeeding Quaternary Period (about the past 2.6 million years), there was considerable oscillation of sea level, leading finally to the emergence of a low-lying isthmus that broadened northward to a low-lying open coastal plain. There the Nile delta once extended farther east—as a result of periods of abundant rainfall coincident with the Pleistocene Epoch (2,588,000 to 11,700 years ago)—and two river arms, or distributaries, formerly crossed the northern isthmus, one branch reaching the Mediterranean Sea at the narrowest point of the isthmus and the other entering the sea some 14.5 km (9 miles) east of present Port Said.

Physiography

Topographically, the Isthmus of Suez is not uniform. There are three shallow water-filled depressions: Lake Manzala, Lake Timsah, and the Bitter Lakes; though distinguished as Great and Little, the Bitter Lakes form one continuous sheet of water. A number of more-resistant bands of limestone and gypsum obtrude in the south of the isthmus, and another significant feature is a narrow valley leading from Lake Timsah southwestward toward the middle Nile delta and Cairo. The isthmus is composed of marine sediments, coarser sands, and gravels deposited in the early periods of abundant rainfall, Nile alluvium (especially to the north), and windblown sands.

When first opened in 1869, the canal consisted of a channel barely 8 metres (26 feet) deep, 22 metres (72 feet) wide at the bottom, and 61 to 91 metres (200 to 300 feet) wide at the surface. To allow ships to pass each other, passing bays were built every 8 to 10 km (5 to 6 miles). Construction involved the excavation and dredging of 74 million cubic metres (97 million cubic yards) of sediments. Between 1870 and 1884 some 3,000 groundings of ships occurred because of the narrowness and tortuousness of the channel. Major improvements began in 1876, and, after successive widenings and deepenings, the canal by the 1960s had a minimum width of 55 metres (179 feet) at a depth of 10 metres (33 feet) along its banks and a channel depth of 12 metres (40 feet) at low tide. Also in that period, passing bays were greatly enlarged and new bays constructed, bypasses were made in the Bitter Lakes and at Al-Ballāḥ, stone or cement cladding and steel piling for bank protection were almost entirely completed in areas particularly liable to erosion, tanker anchorages were deepened in Lake Timsah, and new berths were dug at Port Said to facilitate the grouping of ships in convoy.

Plans that had been made in 1964 for further enlargement were overtaken by the Arab-Israeli war of June 1967, during which the canal was blocked. The canal remained inoperative until June 1975, when it was reopened and improvements were recommenced. In 2015 the Egyptian government finished a nearly $8.5 billion project to upgrade the canal and significantly increase its capacity; nearly 29 km (18 miles) were added to its original length of 164 km (102 miles).
