The spire that will one day reach a point 1,776 feet above Lower Manhattan on the ever-progressing World Trade Center is en route to New York via a barge from Valleyfield, Quebec, Canada. The Port Authority of New York & New Jersey put out a statement that the giant antenna embarked on its 1,500-nautical-mile journey on November 16 and is expected to arrive at Port Newark any day now, but a tracking website doesn’t appear to be working. Smaller pieces will be trucked in over the next month. Each segment of the spire weighs from five to 67 tons. Once the spire is on site, construction is expected to take about three months to complete.
