The Suez Canal (Arabic: قناة السويس qanāt as-suwēs) is a sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez. Constructed by the Suez Canal Company between 1859 and 1869, it was officially opened on 17 November 1869. The canal offers watercraft a more direct route between the North Atlantic and northern Indian oceans via the Mediterranean and Red seas, thus avoiding the South Atlantic and southern Indian oceans and thereby reducing the journey distance from the Arabian Sea to London, for example, by approximately 8,900 kilometres (5,500 mi). It extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. Its length is 193.30 km (120.11 mi), including its northern and southern access channels. In 2012, 17,225 vessels traversed the canal (an average of 47 per day).
The original canal was a single-lane waterway with passing locations in the Ballah Bypass and the Great Bitter Lake. It contains no locks system, with seawater flowing freely through it. In general, the canal north of the Bitter Lakes flows north in winter and south in summer. South of the lakes, the current changes with the tide at Suez.
The Canal was owned by the United Kingdom and France until 1956 when Gamal Abdel Nasser nationalized it, an event which led to the Suez Crisis. The canal is owned and maintained by the Suez Canal Authority (SCA) of Egypt. Under the Convention of Constantinople, it may be used "in time of war as in time of peace, by every vessel of commerce or of war, without distinction of flag".
In August 2014, construction was launched to expand and widen the Ballah Bypass for 35 km (22 mi) to speed the canal's transit time. The expansion was planned to nearly double the capacity of the Suez Canal from 49 to 97 ships a day. At a cost of $8.4 billion, this project was funded with interest-bearing investment certificates issued exclusively to Egyptian entities and individuals. The "New Suez Canal", as the expansion was dubbed, was opened with great fanfare in a ceremony on 6 August 2015.
On 24 February 2016, the Suez Canal Authority officially opened the new side channel. This side channel, located at the northern side of the east extension of the Suez Canal, serves the East Terminal for berthing and unberthing vessels from the terminal. As the East Container Terminal is located on the Canal itself, before the construction of the new side channel it was not possible to berth or unberth vessels at the terminal while the convoy was running.

Ancient west–east canals were built to facilitate travel from the Nile River to the Red Sea. One smaller canal is believed to have been constructed under the auspices of Senusret II or Ramesses II. Another canal, probably incorporating a portion of the first, was constructed under the reign of Necho II, but the only fully functional canal was engineered and completed by Darius I.
The legendary Sesostris (likely either Pharaoh Senusret II or Senusret III of the Twelfth dynasty of Egypt) may have started work on an ancient canal joining the Nile with the Red Sea (1897 BCE – 1839 BCE), when an irrigation channel was constructed around 1850 BCE that was navigable during the flood season, leading into a dry river valley east of the Nile River Delta named Wadi Tumilat. (It is said that in ancient times the Red Sea reached northward to the Bitter Lakes and Lake Timsah.)
One of their kings tried to make a canal to it (for it would have been of no little advantage to them for the whole region to have become navigable; Sesostris is said to have been the first of the ancient kings to try), but he found that the sea was higher than the land. So he first, and Darius afterwards, stopped making the canal, lest the sea should mix with the river water and spoil it.
165. Next comes the Tyro tribe and, the harbour of the Daneoi, from which Sesostris, king of Egypt, intended to carry a ship-canal to where the Nile flows into what is known as the Delta; this is a distance of over 60 miles. Later the Persian king Darius had the same idea, and yet again Ptolemy II, who made a trench 100 feet wide, 30 feet deep and about 35 miles long, as far as the Bitter Lakes.
In the second half of the 19th century, French cartographers discovered the remnants of an ancient north–south canal past the east side of Lake Timsah and ending near the north end of the Great Bitter Lake. This proved to be the celebrated canal made by the Persian king Darius I, as his stele commemorating its construction was found at the site. (This ancient, second canal may have followed a course along the shoreline of the Red Sea when it once extended north to Lake Timsah.) In the 20th century the northward extension of this ancient canal was discovered, extending from Lake Timsah to the Ballah Lakes. This was dated to the Middle Kingdom of Egypt by extrapolating the dates of ancient sites along its course.
The reliefs of the Punt expedition under Hatshepsut, 1470 BCE, depict seagoing vessels carrying the expeditionary force returning from Punt. This suggests that a navigable link existed between the Red Sea and the Nile. Recent excavations in Wadi Gawasis may indicate that Egypt's maritime trade started from the Red Sea and did not require a canal. Evidence seems to indicate its existence by the 13th century BCE during the time of Ramesses II.
According to the Histories of the Greek historian Herodotus, about 600 BCE, Necho II undertook to dig a west–east canal through the Wadi Tumilat between Bubastis and Heroopolis, and perhaps continued it to the Heroopolite Gulf and the Red Sea. Regardless, Necho is reported as having never completed his project.
Herodotus was told that 120,000 men perished in this undertaking, but this figure is doubtless exaggerated. According to Pliny the Elder, Necho's extension to the canal was about 57 English miles, equal to the total distance between Bubastis and the Great Bitter Lake, allowing for winding through valleys. The length that Herodotus tells, of over 1000 stadia (i.e., over 114 miles (183 km)), must be understood to include the entire distance between the Nile and the Red Sea at that time.
With Necho's death, work was discontinued. Herodotus tells that the reason the project was abandoned was because of a warning received from an oracle that others would benefit from its successful completion. Necho's war with Nebuchadnezzar II most probably prevented the canal's continuation.
Necho's project was completed by Darius I of Persia, who ruled over Ancient Egypt after it had been conquered by his predecessor Cambyses II. It may be that by Darius's time a natural waterway passage which had existed between the Heroopolite Gulf and the Red Sea in the vicinity of the Egyptian town of Shaluf (alt. Chalouf or Shaloof), located just south of the Great Bitter Lake, had become so blocked with silt that Darius needed to clear it out so as to allow navigation once again. According to Herodotus, Darius's canal was wide enough that two triremes could pass each other with oars extended, and required four days to traverse. Darius commemorated his achievement with a number of granite stelae that he set up on the Nile bank, including one near Kabret, and a further one a few miles north of Suez. The Darius Inscriptions read:
Saith King Darius: I am a Persian. Setting out from Persia, I conquered Egypt. I ordered this canal dug from the river called the Nile that flows in Egypt, to the sea that begins in Persia. When the canal had been dug as I ordered, ships went from Egypt through this canal to Persia, even as I intended.— Darius Inscription
The canal left the Nile at Bubastis. An inscription on a pillar at Pithom records that in 270 or 269 BCE, it was again reopened, by Ptolemy II Philadelphus. In Arsinoe, Ptolemy constructed a navigable lock, with sluices, at the Heroopolite Gulf of the Red Sea, which allowed the passage of vessels but prevented salt water from the Red Sea from mingling with the fresh water in the canal.
The Red Sea is believed by some historians to have gradually receded over the centuries, its coastline slowly moving southward away from Lake Timsah and the Great Bitter Lake. Coupled with persistent accumulations of Nile silt, maintenance and repair of Ptolemy's canal became increasingly cumbersome over each passing century.
By the 8th century, a navigable canal existed between Old Cairo and the Red Sea, but accounts vary as to who ordered its construction—either Trajan or 'Amr ibn al-'As, or Omar the Great. This canal was reportedly linked to the River Nile at Old Cairo and ended near modern Suez. A geography treatise by Dicuil reports a conversation with an English monk, Fidelis, who had sailed on the canal from the Nile to the Red Sea during a pilgrimage to the Holy Land in the first half of the 8th century
The successful 1488 navigation of southern Africa by Bartolomeu Dias opened a direct maritime trading route to India and the spice islands, and forever changed the balance of Mediterranean trade. One of the most prominent losers in the new order, as former middlemen, was the former spice trading center of Venice.
Venetian leaders, driven to desperation, contemplated digging a waterway between the Red Sea and the Nile—anticipating the Suez Canal by almost 400 years—to bring the luxury trade flooding to their doors again. But this remained a dream.— Colin Thubron, Seafarers: The Venetians (1980), p. 102
During the 16th century, the Ottoman Grand Vizier Sokollu Mehmed Pasha attempted to construct a canal connecting the Red Sea and the Mediterranean. This was motivated by a desire to connect Constantinople to the pilgrimage and trade routes of the Indian Ocean, as well as by strategic concerns—as the European presence in the Indian Ocean was growing, Ottoman mercantile and strategic interests were increasingly challenged, and the Sublime Porte was increasingly pressed to assert its position. A navigable canal would allow the Ottoman Navy to connect its Red Sea, Black Sea, and Mediterranean fleets. However, this project was deemed too expensive, and was never completed.
During the French campaign in Egypt and Syria in late 1798, Napoleon showed an interest in finding the remnants of an ancient waterway passage. This culminated in a cadre of archaeologists, scientists, cartographers and engineers scouring northern Egypt. Their findings, recorded in the Description de l'Égypte, include detailed maps that depict the discovery of an ancient canal extending northward from the Red Sea and then westward toward the Nile.
Later, Napoleon, who would become French Emperor in 1804, contemplated the construction of a north–south canal to connect the Mediterranean with the Red Sea. But the plan was abandoned because it wrongly concluded that the waterway would require locks to operate. These would be very expensive and take a long time to construct. This decision was based on an erroneous belief that the Red Sea was 10 m (33 ft) higher than the Mediterranean. The error was the result of using fragmentary survey measurements taken in wartime during Napoleon's Egyptian Expedition. In 1819 the Pacha of Egypt undertook some canal work.
Although the alleged difference in sea levels could be problematic for construction, the idea of finding a shorter route to the east remained alive. In 1830, F. R. Chesney submitted a report to the British government that stated that there was no difference in elevation and that the Suez Canal was feasible, but his report received no further attention. Lieutenant Waghorn established his "Overland Route", which transported post and passengers to India via Egypt. Linant de Bellefonds, a French explorer of Egypt, became chief engineer of Egypt's Public Works. In addition to his normal duties, he surveyed the Isthmus of Suez and made plans for the Suez Canal. French Saint-Simonianists showed an interest in the canal and in 1833, Barthélemy Prosper Enfantin tried to draw Muhammad Ali's attention to the canal but was unsuccessful. Alois Negrelli, the Austrian railroad pioneer, became interested in the idea in 1836. In 1846, Prosper Enfantin's Société d'Études du Canal de Suez invited a number of experts, among them Robert Stephenson, Negrelli and Paul-Adrien Bourdaloue to study the feasibility of the Suez Canal (with the assistance of Linant de Bellefonds). Bourdaloue's survey of the isthmus was the first generally accepted evidence that there was no practical difference in altitude between the two seas. Britain, however, feared that a canal open to everyone might interfere with its India trade and therefore preferred a connection by train from Alexandria via Cairo to Suez, which was eventually built by Stephenson.
In 1854 and 1856, Ferdinand de Lesseps obtained a concession from Sa'id Pasha, the Khedive of Egypt and Sudan, to create a company to construct a canal open to ships of all nations. The company was to operate the canal for 99 years from its opening. De Lesseps had used his friendly relationship with Sa'id, which he had developed while he was a French diplomat in the 1830s. As stipulated in the concessions, Ferdinand convened the International Commission for the piercing of the isthmus of Suez (Commission Internationale pour le percement de l'isthme des Suez) consisting of 13 experts from seven countries, among them John Robinson McClean, later President of the Institution of Civil Engineers in London, and again Negrelli, to examine the plans developed by Linant de Bellefonds, and to advise on the feasibility of and the best route for the canal. After surveys and analyses in Egypt and discussions in Paris on various aspects of the canal, where many of Negrelli's ideas prevailed, the commission produced a unanimous report in December 1856 containing a detailed description of the canal complete with plans and profiles. The Suez Canal Company (Compagnie universelle du canal maritime de Suez) came into being on 15 December 1858.
Work started on the shore of the future Port Said on 25 April 1859.
The excavation took some 10 years using forced labour (corvée) of Egyptian workers during the first years. Some sources estimate that over 30,000 people were working on the canal at any given period, that more than 1.5 million people from various countries were employed, and that thousands of labourers died, many of them from cholera and similar epidemics.
The British government had opposed the project from the outset to its completion. As one of the diplomatic moves against the canal, it disapproved of the use of "slave labour" of forced workers. The British Empire was the major global naval force and officially condemned the forced work and sent armed Bedouins to start a revolt among workers. Involuntary labour on the project ceased, and the viceroy condemned the corvée, halting the project.
Angered by the British opportunism, de Lesseps sent a letter to the British government remarking on the British lack of remorse a few years earlier when forced workers died in similar conditions building the British railway in Egypt.
Initially international opinion was skeptical and Suez Canal Company shares did not sell well overseas. Britain, Austria, and Russia did not buy a significant number of shares. However, with assistance from the Cattaui banking family, and their relationship with James de Rothschild of the French House of Rothschild bonds and shares were successfully promoted in France and other parts of Europe. All French shares were quickly sold in France. A contemporary British skeptic claimed "One thing is sure... our local merchant community doesn't pay practical attention at all to this grand work, and it is legitimate to doubt that the canal's receipts... could ever be sufficient to recover its maintenance fee. It will never become a large ship's accessible way in any case."
The canal opened under French control on 17 November 1869. The opening was performed by Khedive Isma'il Pasha of Egypt and Sudan, and at Ismail's invitation French Empress Eugenie in the Imperial yacht L'Aigle piloted by Napoléon Coste, upon whom the Khedive bestowed the Ottoman Order of the Medjidie.
Although L'Aigle was officially the first vessel through the canal, HMS Newport, captained by George Nares, passed through it first. On the night before the canal was due to open, Captain Nares navigated his vessel, in total darkness and without lights, through the mass of waiting ships until it was in front of L'Aigle. When dawn broke, the French were horrified to find that the Royal Navy was first in line and that it would be impossible to pass them. Nares received both an official reprimand and an unofficial vote of thanks from the Admiralty for his actions in promoting British interests and for demonstrating such superb seamanship.
Although numerous technical, political, and financial problems had been overcome, the final cost was more than double the original estimate.
After the opening, the Suez Canal Company was in financial difficulties. The remaining works were completed only in 1871, and traffic was below expectations in the first two years. De Lesseps therefore tried to increase revenues by interpreting the kind of net ton referred to in the second concession (tonneau de capacité) as meaning a ship's cargo capacity and not only the theoretical net tonnage of the "Moorsom System" introduced in Britain by the Merchant Shipping Act in 1854. The ensuing commercial and diplomatic activities resulted in the International Commission of Constantinople establishing a specific kind of net tonnage and settling the question of tariffs in its protocol of 18 December 1873. This was the origin of the Suez Canal Net Tonnage and the Suez Canal Special Tonnage Certificate, both of which are still in use today.
The canal had an immediate and dramatic effect on world trade. Combined with the American transcontinental railroad completed six months earlier, it allowed the world to be circled in record time. It played an important role in increasing European colonization of Africa. The construction of the canal was one of the reasons for the Panic of 1873, because goods from the Far East were carried in sailing vessels around the Cape of Good Hope and were stored in British warehouses. An inability to pay his bank debts led Said Pasha's successor, Isma'il Pasha, in 1875 to sell his 44% share in the canal for £4,000,000 ($19.2 million) equivalent to ₤432 million to ₤456 million ($540 million to $570 million) to the government of the United Kingdom. French shareholders still held the majority. Local unrest caused the British to invade in 1882 and take full control, although nominally Egypt remained part of the Ottoman Empire. The British representative 1883 to 1907 was Evelyn Baring, 1st Earl of Cromer, who reorganized and modernized the government and suppressed rebellions and corruption, thereby facilitating increased traffic on the canal.
The Convention of Constantinople in 1888 declared the canal a neutral zone under the protection of the British, who had occupied Egypt and Sudan at the request of Khedive Tewfiq to suppress the Urabi Revolt against his rule. The revolt went on from 1879 to 1882. As a result of British involvement on the side of Khedive Tewfiq, Britain gained control of the canal in 1882. The British defended the strategically important passage against a major Ottoman attack in 1915, during the First World War. Under the Anglo-Egyptian Treaty of 1936, the UK retained control over the canal. The canal was again strategically important in the 1939–1945 Second World War, and Italo-German attempts to capture it were repulsed during the North Africa Campaign, during which the canal was closed to Axis shipping. In 1951 Egypt repudiated the treaty and in October 1954 the UK agreed to remove its troops. Withdrawal was completed on 18 July 1956.
Main article: Suez Crisis
Because of Egyptian overtures towards the Soviet Union, the United Kingdom and the United States withdrew their pledge to support the construction of the Aswan Dam. Egyptian President Gamal Abdel Nasser responded by nationalizing the canal on 26 July 1956 and transferring it to the Suez Canal Authority, intending to finance the dam project using revenue from the canal. On the same day that the canal was nationalized Nasser also closed the Straits of Tiran to all Israeli ships. This led to the Suez Crisis in which the UK, France, and Israel invaded Egypt. According to the pre-agreed war plans under the Protocol of Sèvres, the Israelis invaded the Sinai Peninsula on 29 October, forcing Egypt to engage them militarily, and allowing the Anglo-French partnership to declare the resultant fighting a threat to stability in the Middle East and enter the war - officially to separate the two forces but in reality to regain the Canal and bring down the Nasser government.
To save the British from what he thought was a disastrous action and to stop the war from a possible escalation, Canadian Secretary of State for External Affairs Lester B. Pearson proposed the creation of the first United Nations peacekeeping force to ensure access to the canal for all and an Israeli withdrawal from the Sinai Peninsula. On 4 November 1956, a majority at the United Nations voted for Pearson's peacekeeping resolution, which mandated the UN peacekeepers to stay in Sinai unless both Egypt and Israel agreed to their withdrawal. The United States backed this proposal by putting pressure on the British government through the selling of sterling, which would cause it to depreciate. Britain then called a ceasefire, and later agreed to withdraw its troops by the end of the year. Pearson was later awarded the Nobel Peace Prize. As a result of damage and ships sunk under orders from Nasser the canal was closed until April 1957, when it was cleared with UN assistance. A UN force (UNEF) was established to maintain the free navigability of the canal, and peace in the Sinai Peninsula.
In May 1967, Nasser ordered the UN peacekeeping forces out of Sinai, including the Suez Canal area. Israel objected to the closing of the Straits of Tiran to Israeli shipping. The canal had been closed to Israeli shipping since 1949, except for a short period in 1951–1952.
After the 1967 Six-Day War, Israeli forces occupied the Sinai peninsula, including the entire east bank of the Suez Canal. Unwilling to allow the Israelis to use the canal, Egypt immediately imposed a blockade which closed the canal to all shipping. Fifteen cargo ships, known as the "Yellow Fleet", were trapped in the canal, and would remain there until 1975.
After the Yom Kippur War the United States initiated Operation Nimbus Moon. The amphibious assault ship USS Inchon (LPH-12) was sent to the Canal, carrying 12 RH-53D minesweeping helicopters of HM-12. These partly cleared the canal between May and December 1974. She was relieved by the LST USS Barnstable County (LST1197). The British Royal Navy initiated Operation Rheostat and Task Group 65.2 provided for Operation Rheostat One (six months in 1974), the minehunters HMS Maxton, HMS Bossington, and HMS Wilton, the Fleet Clearance Diving Team (FCDT) and HMS Abdiel, a practice minelayer/MCMV support ship; and for Operation Rheostat Two (six months in 1975) the minehunters HMS Hubberston and HMS Sheraton, and HMS Abdiel. When the Canal Clearance Operations were completed, the canal and its lakes were considered 99% clear of mines. The canal was then reopened by Egyptian President Anwar Sadat aboard an Egyptian destroyer, which led the first convoy northbound to Port Said in 1975. At his side stood the Iranian Crown Prince Reza Pahlavi, delegated to represent his father, Mohammed Reza Pahlavi, the Shah of Iran. The cruiser USS Little Rock was the only American naval ship in the convoy.
The UNEF mandate expired in 1979. Despite the efforts of the United States, Israel, Egypt, and others to obtain an extension of the UN role in observing the peace between Israel and Egypt, as called for under the Egypt–Israel Peace Treaty of 1979, the mandate could not be extended because of the veto by the Soviet Union in the UN Security Council, at the request of Syria. Accordingly, negotiations for a new observer force in the Sinai produced the Multinational Force and Observers (MFO), stationed in Sinai in 1981 in coordination with a phased Israeli withdrawal. It is there under agreements between the United States, Israel, Egypt, and other nations.
Main article: New Suez Canal
In the summer of 2014, months after taking office as President of Egypt, Abdel Fattah el-Sisi ordered the expansion of the Ballah Bypass from 61 metres (200 ft) wide to 312 metres (1,024 ft) wide for 35 kilometres (22 mi). The project was called the New Suez Canal, as it would allow ships to transit the canal in both directions simultaneously. The project cost more than $8 billion and was completed within one year. Sisi declared the expanded channel open for business in a ceremony on 6 August 2015.

When built, the canal was 164 km (102 mi) long and 8 m (26 ft) deep. After several enlargements, it is 193.30 km (120.11 mi) long, 24 m (79 ft) deep and 205 metres (673 ft) wide. It consists of the northern access channel of 22 km (14 mi), the canal itself of 162.25 km (100.82 mi) and the southern access channel of 9 km (5.6 mi).
The so-called New Suez Canal, functional since 6 August 2015, currently has a new parallel canal in the middle part, with its length over 35 km (22 mi). The current parameters of the Suez Canal, including both individual canals of the parallel section are: depth 23 to 24 metres (75 to 79 ft) and width at least 205 to 225 metres (673 to 738 ft) (that width measured at 11 metres (36 ft) of depth).

The canal allows passage of ships up to 20 m (66 ft) draft or 240,000 deadweight tons and up to a height of 68 m (223 ft) above water level and a maximum beam of 77.5 m (254 ft) under certain conditions. The canal can handle more traffic and larger ships than the Panama Canal, as Suezmax dimensions are greater than both Panamax and New Panamax. Some supertankers are too large to traverse the canal. Others can offload part of their cargo onto a canal-owned boat to reduce their draft, transit, and reload at the other end of the canal.
The canal has no locks because of the flat terrain, and the minor sea level difference between each end is inconsequential for shipping. As the canal has no sea surge gates, the ports at the ends would be subject to the sudden impact of tsunamis from the Mediterranean Sea and Red Sea, according to a 2012 article in the Journal of Coastal Research.
There is one shipping lane with passing areas in Ballah-Bypass near El Qantara and in the Great Bitter Lake. On a typical day, three convoys transit the canal, two southbound and one northbound. The passage takes between 11 and 16 hours at a speed of around 8 knots (15 km/h; 9 mph). The low speed helps prevent erosion of the banks by ships' wakes.
By 1955, about two-thirds of Europe's oil passed through the canal. Around 8% of world sea trade is carried via the canal. In 2008, 21,415 vessels passed through the canal and the receipts totaled $5.381 billion, with an average cost per ship of $251,000.
New Rules of Navigation came into force on 1 January 2008, passed by the board of directors of the Suez Canal Authority (SCA) to organise vessels' transit. The most important amendments include allowing vessels with 62-foot (19 m) draught to pass, increasing the allowed breadth from 32 metres (105 ft) to 40 metres (130 ft) (following improvement operations), and imposing a fine on vessels using divers from outside the SCA inside the canal boundaries without permission. The amendments allow vessels loaded with dangerous cargo (such as radioactive or flammable materials) to pass if they conform with the latest amendments provided by international conventions.
Predominant currents in the Mediterranean Sea for June
Before August 2015, the canal was too narrow for free two-way traffic, so ships would pass in convoys and use bypasses. The by-passes were 78 km (48 mi) out of 193 km (120 mi) (40%). From north to south, they are: Port Said by-pass (entrances) 36.5 km (23 mi), Ballah by-pass & anchorage, 9 km (6 mi), Timsah by-pass 5 km (3 mi), and the Deversoir by-pass (northern end of the Great Bitter Lake) 27.5 km (17 mi). The bypasses were completed in 1980.
Typically, it would take a ship 12 to 16 hours to transit the canal. The canal's 24-hour capacity was about 76 standard ships.
In August 2014, Egypt chose a consortium that includes the Egyptian army and global engineering firm Dar Al-Handasah to develop an international industrial and logistics hub in the Suez Canal area, and began the construction of a new canal section from km 60 to km 95 combined with expansion and deep digging of the other 37 km of the canal. This will allow navigation in both directions simultaneously in the 72 km long central section of the canal. These extensions were formally opened on 6 August 2015 by President Al-Sisi.
Since the canal does not cater to unregulated two-way traffic, all ships transit in convoys on regular times, scheduled on a 24-hour basis. Each day, a single northbound convoy starts at 04:00 from Suez. At dual lane sections, the convoy uses the eastern route. Synchronised with this convoy's passage is the southbound convoy. It starts at 03:30 from Port Said and so passes the Northbound convoy in the two-lane section[clarification needed].
From north to south, the crossings are:
A railway on the west bank runs parallel to the canal for its entire length.
The main alternative is around Cape Agulhas, the southernmost point of Africa, commonly referred as the Cape of Good Hope route. This was the only sea route before the canal was constructed, and when the canal was closed. It is still the only route for ships that are too large for the canal. In the early 21st century, the Suez Canal has suffered from diminished traffic due to piracy in Somalia, with many shipping companies choosing to take the long route instead. Between 2008 and 2010, it is estimated that the canal lost 10% of traffic due to the threat of piracy, and another 10% due to the financial crisis. An oil tanker going from Saudi Arabia to the United States has 2,700 mi (4,345 km) longer to go when taking the route south of Africa rather than the canal.
Before the canal's opening in 1869, goods were sometimes offloaded from ships and carried overland between the Mediterranean and the Red Sea.
In recent years, the shrinking Arctic sea ice has made the Northern Sea Route feasible for commercial cargo ships between Europe and East Asia during a six-to-eight-week window in the summer months, shortening the voyage by thousands of miles compared to that through the Suez Canal. According to polar climate researchers, as the extent of the Arctic summer ice pack recedes the route will become passable without the help of icebreakers for a greater period each summer.
Main article: Lessepsian migration
The opening of the canal created the first salt-water passage between the Mediterranean Sea and the Red Sea. Although the Red Sea is about 1.2 m (4 ft) higher than the eastern Mediterranean, the current between the Mediterranean and the middle of the canal at the Bitter Lakes flows north in winter and south in summer. The current south of the Bitter Lakes is tidal, varying with the tide at Suez. The Bitter Lakes, which were hypersaline natural lakes, blocked the migration of Red Sea species into the Mediterranean for many decades, but as the salinity of the lakes gradually equalised with that of the Red Sea the barrier to migration was removed, and plants and animals from the Red Sea have begun to colonise the eastern Mediterranean.
The Red Sea is generally saltier and more nutrient-poor than the Atlantic, so the Red Sea species have advantages over Atlantic species in the less salty and nutrient-rich eastern Mediterranean. Accordingly, most Red Sea species invade the Mediterranean biota, and only few do the opposite. This migratory phenomenon is called Lessepsian migration (after Ferdinand de Lesseps) or "Erythrean invasion". Also impacting the eastern Mediterranean, starting in 1968, was the operation of Aswan High Dam across the Nile. While providing for increased human development, the project reduced the inflow of freshwater and ended all natural nutrient-rich silt entering the eastern Mediterranean at the Nile Delta. This provided less natural dilution of Mediterranean salinity and ended the higher levels of natural turbidity, additionally making conditions more like those in the Red Sea.
Invasive species originating from the Red Sea and introduced into the Mediterranean by the canal have become a major component of the Mediterranean ecosystem and have serious impacts on the ecology, endangering many local and endemic species. About 300 species from the Red Sea have been identified in the Mediterranean, and there are probably others yet unidentified. The Egyptian government's intent to enlarge the canal has raised concerns from marine biologists, fearing that this will worsen the invasion of Red Sea species.
Construction of the canal was preceded by cutting a small fresh-water canal called Sweet Water Canal from the Nile delta along Wadi Tumilat to the future canal, with a southern branch to Suez and a northern branch to Port Said. Completed in 1863, these brought fresh water to a previously arid area, initially for canal construction, and subsequently facilitating growth of agriculture and settlements along the canal.
The Suez Canal Economic Zone, sometimes shortened to the Suez Canal Zone, describes the set of locations neighbouring the canal where customs rates have been reduced to zero in order to attract investment. The zone comprises over 600 km2 within the governorates of Port Said, Ismailia and Suez. Projects in the zone are collectively described as the Suez Canal Area Development Project (SCADP).
The zone incorporates the three "Qualifying Industrial Zones" at Port Said, Ismailia and Suez, a 1996 American initiative to encourage economic ties between Israel and its neighbours.
