Panama Weighs Another Canal Expansion at Centennial Mark

A century after the U.S. steamship Ancon first sailed through the Panama Canal, a $5.3 billion expansion delayed by bickering contractors and angry workers is nearing completion. The problem is it might not be big enough.

With the expansion 16 months behind schedule, canal administrator Jorge Quijano said officials are studying whether to dig a fourth set of locks to handle a growing fleet of super-sized ships. Those include the 400-meter-long “Triple E” vessels capable of carrying more than 18,000 containers, four times more than current ships passing through the canal.
