A Cargo ship leaves the Panama Canal Miraflores locks, heading toward the Pacific Ocean, in Panama City April 24, 2006. Panama was set to unveil the biggest-ever expansion of its famous canal on Monday, spending up to $6 billion so it can handle the new generation of mammoth cargo ships and oil tankers. Opened in 1914 at a cost of 25,000 lives, the canal was considered a masterpiece of engineering. It makes a shortcut between the Pacific and Atlantic Oceans, saving ships the long trip around South America and the treacherous Cape Horn. REUTERS/Alberto Lowe
