Three large barges, one carrying 1,400 tons of methanol, were wedged against a dam and partially submerged, on the Ohio River in Louisville, Kentucky, following their detachment from a tugboat.
The Louisville Metropolitan Emergency Services said the navigation accident occurred early Tuesday morning when three barges -- part of a group of ten -- broke free from a tugboat after hitting a structure at the entrance to the Portland Canal near the river's McAlpine Locks and Dam.
