Engineering is the art of making what you want from things you can get.

The Columbia Coastal barge operations will manage the loading and blocking of any equipment it transports. The equipment shipper can rely on the expertise of Columbia Coastal to safely transport heavy equipment for long distances. Transporting construction equipment over the interstate highway system poses more safety risks and equipment damage than transporting by barge. A construction firm's insurance carrier should reduce the liability factor for shipping equipment on the marine highway.
