1) Panama Canal Expansion, Panama
The Panama Canal was built in 1914 and it was scheduled to be expanded in 2016 which it successfully was. With the rise of many new sized ships and other needs of the canal it’s no wonder that the world decided this particular piece of land required an upgrade that will best suit the needs of the sea transport industry of today. The new project should expand the Panama Canal by an additional 3.8 miles which is not a small construction job at all.
