From a story on the Web site of WQOW, Eau Claire:
SUPERIOR, Wis. (AP) – Seven shiploads of wind turbine components are being unloaded at the Duluth-Superior port for transport to wind farms across the Midwest and beyond.
The components are being stored on nearly 50 acres at the Twin Ports before they’re trucked to Illinois, Iowa, North Dakota and even as far as Montana.
100-ton-capacity cranes lift and load generators, blades and hubs onto specially built trucks designed to hold the weight. About 2,000 wind turbine components have come through the Twin Ports so far this year.
The Duluth-Superior port set a record in 2007 when 310,000 freight tons of wind cargo passed through.
