Deck Panel Installation Continues on New Span

Crews continue to set precast concrete deck panels atop the steel girders, install rebar, pour concrete and ready the driving surface of the eastbound span. This is what the westbound span looked like before its final driving surface was applied. Deck panels were interlocked via their hairpin reinforcing steel bars; the spaces between them were closed with reinforcing concrete.

They’re doing other work, too, including removing sections of the Tappan Zee Bridge. Their order is the section south of the center, a cantilever truss weighing 4,560 tons; strand jacks will then help lower the main span section closest to Westchester, an anchor span weighing 5,350 tons, onto barges. Then comes the section south of the center, followed by the section closest to Rockland.

I’d like to know what you think.
