Educational Outreach explains the Pulley System

This cool interactive demonstration at Stemtastics in Larchmont showed kids and parents how pulleys work to lift weights like structural steel on bridges.

The I Lift NY super crane’s versabar (system) can lift up to 1700 metric tons (1928 US tons), much-needed strength when lifting pieces of structural steel.

It’s getting closer to when two-way traffic will shift to the the westbound span; however, I’m wondering how the belvederes will be constructed while cars are on that span. Will one lane be closed so crews can safely work on the shared use path? Will the belvederes be completed before traffic moves to the westbound span?

Here’s a view of the westbound span, where workers lower formwork over rebar. Getting there! Photos courtesy of New York State Thruway Authority.

I’d like to know what you think.
