Business Insider: "The $5.2 billion expansion of the Panama Canal was expected to make US East Coast ports more competitive for cargo ships carrying televisions, tennis shoes, and other products from Asia.
But those hopes are fading. As the wider, deeper canal nears its debut next month, ports that stand to gain aren't ready to handle the bigger ships that will come through.
The harbor in Charleston, South Carolina, for instance, is too shallow. The Bayonne Bridge outside New York and New Jersey terminals is too low."
