Earlier this month when we started Part 1 of the Erecting The Needle series, concrete was being poured and leg pedestals were being bolted down. Worked progressed through the Summer of 1961. Each double-column leg was made of three massive steel I beams joined at the edges. These beams were three feet wide and seventeen inches across the flanged sides. The steel would weigh 300 pounds per foot — some as many as 90 feet long. All told (with fittings), each column was to weigh more than 90,000 pounds. Check out the photos below and click on the thumbnails for larger versions. Don’t forget to check out Part 1 of this Erecting The Needle feature, if you haven’t already. [see also: Part 3, Part 4]
