NYT looks at the $19 billion renovation of Kennedy Airport in New York. Smart ways are being adopted to avoid tying up the highways around the airport with trucks by sending stone and other supplies from quarries 125 miles away by water up the Hudson river to a waterside dock on the 5000 acre Kennedy campus. The executive director of The Port Authority of New York that runs the Kennedy Airport, one of the busiest in the world, says this avoids 300,000 truck trips spanning 1.5 million miles.
