In 2007, work began on a $5.25 billion expansion project that enabled the canal to handle post-Panamax ships; that is, those exceeding the dimensions of so-called Panamax vessels, built to fit through the canal, whose locks are 110 feet wide and 1,000 feet long. The expanded canal, which was completed in 2016, can handle cargo vessels carrying 14,000 20-foot containers, nearly three times the amount previously accommodated. The expansion project also includes a new, larger set of locks and the widening and deepening of existing navigational channels. However, while the new locks are able to fit many modern ships, they still aren't super-sized enough for some vessels, such as Maersk’s Triple E class ships, the planet’s biggest container ships, which measure 194 feet wide and 1,312 feet long, with a capacity of 18,000 20-foot containers.
