It is amazing what you can see passing through New York harbor. Those awake in the hours before dawn this morning may have seen a highway bridge under tow down the East River around the Battery and across the Hudson River to Jersey City. It was the Willis Avenue Bridge which has spanned the Harlem River for 110 years once carrying 70,000 vehicles daily between upper Manhattan and the South Bronx. The old bridge has been replaced by a new prefabricated bridge. Plans are for the old steel to be cut up and recycled and the concrete to be used for fill.
