A study by the Panama Canal Authority in the early 2000 showed the canal would reach its maximum sustainable capacity between 2009 and 2012.
A bold proposal?
Then-Panamanian President Martín Torrijos formally proposed a project with three goals:
Build two new sets of bigger locks, one each on the Atlantic and Pacific sides, and excavated new channels to the new locks.
Widen and deepen existing channels.
Raise the maximum operating water level of Gatun Lake.
The project was to be completed by 2014 – to coincide with the canals 100th anniversary. A national referendum approved the proposal by a 76.8 percent majority on October 22.
