How the Evergreen's ship got stuck in the Suez Canal and created the world's heaviest traffic jam.

The 400-meter, 220,000 ton Ever Given, created a shipper's nightmare and captured the public's attention when it blocked the Suez Canal on March 23. It created a traffic jam of more than 360 ships as of Sunday and cost billions in delayed shipments. 

The Ever Given was stuck near the Egyptian city of Suez, about 6 km north of the canal's southern entrance. It was in a single-lane section of the canal, about 300 meters wide.

Its owners originally said high winds in a sandstorm pushed the ship sideways, wedging it into both banks of the waterway. However, the chairman of Egypt's Suez Canal Authority said on Saturday, without giving details, that weather conditions "were not the main reasons" for the grounding, and that "there may have been technical or human reasons," the BBC reported. An investigation is ongoing. 

As of yesterday, the ship, that blocked the Suez Canal for six days was freed and continued its journey. This was the result of successful push and tow manoeuvres which led to the restoration of 80% of the vessel's direction. 

The estimated damage that the blockage caused to the world economy is around $80 billion.
