The Panama Canal expansion project,

The Panama Canal expansion project, also called the Third Set of Locks Project, doubled the capacity of the Panama Canal by adding a new lane of traffic allowing for a larger number of ships, and increasing the width and depth of the lanes and locks allowing larger ships to pass. The new larger size of ships, called New Panamax, are about one and a half times the previous Panamax size and can carry over twice as much cargo.
