Dominion Atlantic Railway Bear River Bridge 17 December 2011 12:27pm
The rising tide is about halfway between low and high.
There is a strong upstream current (from left to right in this view).
The barge is being held in position, against this strong tidal current,
by the three spud legs, here seen to be fully deployed – extended
downward and pushed into the sea floor, to resist any horizontal
movement of the barge, while leaving it free to move vertically
as it is lifted by the swiftly rising sea surface. The tugboat
Lina, tightly lashed to the barge, is idling.
