Shippers in Virginia have a few hours to move 5,700 tons of cargo onto a barge, but a thunderstorm threatens the chances of completing the task; one of the world's largest cruise ships needs to restock.

A nearly 2 billion dollar bridge is being built and Mega Shippers need to lift portions of the bridge 180 feet above a river; in Florida, $150 million-worth of yachts need to be moved without incident.
