After a grounded container ship blocked traffic on the Suez Canal for six days, the key shipping route through Egypt reopened on March 29, 2021. In this case, the tides in the Suez Canal rose about 46 centimeters (18 inches) above normal on March 29. After being dislodged, the ship continued north into Great Bitter Lake, a wider part of the Suez Canal system. While ship traffic began moving through the canal again on March 29, it will take some time to clear the queue of waiting ships. It could take up to three days to clear the backlog, according to the Suez Canal Authority.
