And this shipping season is expected to be the busiest one in the last twenty years for Erie Sand and Gravel.
The evidence of that is a line of GE locomotives at the port right now.
More than 200 million tons of cargo is shipped every year across the Great Lakes according to the National Oceanic and Atmospheric Administration.
The shipping season started a bit late this year because of the heavy ice cover across all five bodies of water.
Typically crews work through the winter but Port Director Ray Schreckengost says things that normally take five days to complete took at least ten days this winter.
But that delay isn't slowing down the business at Erie Sand and Gravel now.
They're ready to bring in six transformers that come in at about 200 tons each.
Plus GE Transportation is lining up locomotives on the shipping docks that will end up in Mozambique South Africa.
There will be fifty in total shipped from Erie Sand and Gravel.
Donjon shipbuilding and repair had one of its busiest seasons this year too.
They repaired three ships plus one that came in last week for emergency repairs.
