Concept note-1: -Building the Panama Canal, 1903–1914.
Concept note-2: -It was the greatest infrastructure project the world had ever seen. When the 48 mile-long Panama Canal officially opened in 1914, after 10 years of construction, it fulfilled a vision that had tempted people for centuries, but had long seemed impossible.
Concept note-3: -The project was plagued by poor planning, engineering problems and tropical diseases that killed thousands of workers. De Lesseps intended to build the canal at sea level, without locks, like the Suez Canal, but the excavation process proved far more difficult than anticipated.
Concept note-4: -Though it took nearly four centuries for his dream to materialize, since its inauguration, Panama Canal has reduced the sailing distance from the Atlantic to the Pacific and vice versa by a vast 8000 nautical miles (approximately). If we sail with an average speed of about say 15 knots, then it will be 22 long days!
