The pusher barges you refer to are actually ATB's and the ATB in the picture that you see underway is the tug Joyce L VanEnkevort and barge Great Lakes Trader. She does not and would not be moving back and forth on the dock to clear the way for the freighters, in fact she normally runs Escanaba to Indiana Harbor all winter unassistted by CG or others and is usually breaking trail for the freighters not the other way around.
