PIERMONT - State officials are threatening the construction company building the new Tappan Zee Bridge with fines after another barge broke loose and floated down the Hudson River yesterday.

Brian Conybeare, the special advisor to Gov. Andrew Cuomo on the New Tappan Zee Bridge Project, says the New York State Thruway Authority is going to withhold up to $1 million a month in project fees because of the ongoing issues with barges.

This is the third time a barge has broken loose since September.

The barge came loose at around 4 p.m. Sunday and came close to dockside in Dobbs Ferry before authorities were able to get it under control. Piermont Police Chief Michael O'Shea says he's concerned about the safety of recreational boaters as the weather gets warmer.

GPS tracking systems are being installed on barges with the goal of having them all fully operational by the end of April.
