One of four ginormous crossbeams being lifted onto two of the main span towers/NYSTA

The I Lift NY got another workout setting the first crossbeam — held in place by temporary steelwork while crews connected it — between two main span towers.

They’re enormous (revealed last week) at 26 feet high and 16 feet-six inches wide, and are different lengths: the eastbound span’s crossbeams are 60 feet long, and the westbound span’s are 70 feet long. Do you know why? All together now: the shared use path adds the extra width.

See how the bridge’s starting to take shape like in the videos and diagrams we see/NYSTA

Credit Coastal Precast Systems (CPS) in Chesapeake, Virginia, fabricated the 645-ton eastbound crossbeams and the 742-ton westbound crossbeams, which came north via a floating barge.

I’d like to know what you think.
