Kosciuszko’s final chapter

THE REMNANTS of the old Kosciuszko Bridge are coming down.

Gov. Cuomo announced that the bridge’s remaining approaches on the Queens and Brooklyn sides of Newtown Creek “will be lowered to the ground through an energetic felling process” at 8 a.m. Sunday.

An estimated 22 million pounds of steel from the structures will be recycled as scrap metal.

A traditional dismantling would have taken months, a state official said, so cuts were made to the trestles and 944 small 12-pound charges will be used to bring down each span.

The remnants will drop onto earthen berms to minimize dust and debris.

The controlled demolition will free up space for the completion of the second new span, set to open in 1919.

Roads in the area, including the Brooklyn-Queens Expressway, will be closed to traffic for roughly a quarter of an hour as the bridge is lowered.

The former bridge’s main span, which opened in 1939 and closed in April, was lowered onto a barge and removed on July 25 after the first expanse of the replacement bridge opened.
