PIERMONT - A construction barge from the Tappan Zee Bridge project somehow got loose and floated down the Hudson River yesterday.

The Rockland County Sheriff's Department says someone spotted the barge at around 6 p.m. yesterday.

Authorities took hold of it as it started to approach the Piermont shore.

Officials say the barge, which was not carrying supplies or equipment, could have been very dangerous.

A tugboat from Tappan Zee Constructors eventually took possession of the barge.

Tappan Zee Constructors and the New York Thruway Authority say they are investigating the incident.
