As you can see from the featured picture and this one the Panama Canal has come a long way since first created. This is a picture of the original construction being done.
And now they are working on an expansion to accommodate the new larger ships that are being build.
The day we took a tour of the locks we watched this vehicle carrier go by the hotel before 8:00am.
And when we got to the locks a couple hours later their it was in the locks getting ready to move on through the canal.
Supposedly the new expansion is to be finished by December of this year. They are doing this expansion on bothe the Pacific and Atlantic sides of the canal.
