This is an incredible feat of engineering and almost like watching the building of the pyramids.   More here.

The Panama Canal Authority (ACP) reported on Tuesday, October 11, the culmination of the third phase of dry excavation of the Pacific access channel, as part of the expansion program of the waterway. This channel will join the third set of locks to the Gaillard Cut and Gatun Lake, according to the plan. This project had a cost of design, contracting, and administration of $36.6 million dollars. It included the excavation of 8.2 million cubic meters of material, the cleaning of 190 hectares of old military firing ranges, and the leveling of Paradise Hill, from 46 meters to 27.5 meters above sea level, the ACP said in a statement. To date the ACP has completed three of the four phases of dry excavation of 6.1 kilometer long channel, that will be used by post-Panamax vessels once the Panama Canal Expansion program is completed.
