A barge carrying eight sections of the massive spire that will make One World Trade Center the nation’s tallest building is en route to New York from Canada down the Atlantic seaboard.

The segments — which left Valleyfield, Quebec, on Friday — range from 5 to 67 tons.

They are expected to arrive in Port Newark sometime next week following a 1,500-mile journey on the Atlantic Salvor barge.

Once in New Jersey, the spires will be transferred to Manhattan.

The 10 smaller sections — all of which were made in Canada — will be sent down in December via trucks.

When all the sections have arrived and the spire is complete, it will be placed on top of One World Trade Center, reaching a height of 1,776 feet — the tallest building in the Western Hemisphere.

Even without the spire, the still-under-construction World Trade Center has already eclipsed the Empire State Building’s 1,250 feet to make it the tallest building in New York.

The Port Authority has created a tracking Web site to follow the barge’s journey at MarineTraffic.com.
