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.

Noise Barrier Installation Continues — & Lights

You know about the hour-long light show under the bridge last month, right?

TZC also connected the Westchester and Rockland approaches to the main span last month. Getting closer! I wonder where they’ll put this happy sign:

Crews continue installing concrete noise barriers chosen way back when along the southbound Thruway and the northbound side (next to the future shared use path) in South Nyack.

I’d like to know what you think.

Since media were invited onto the new westbound span, crews connected the Westchester approach and the main span, the Rockland approach and the main span are being connected, and there will soon be a fifth overhead gantry. Did we miss the fourth?

Tha main span navigation channel continues to be closed periodically until next December. While boaters may be pleased to hear this, I’d like to enjoy the spring, summer and fall before winter comes around again.

ICYMI: Checking in with the @NewNYBridge

Basking in your team’s Super Bowl win? You may have missed these last week.

Bridge sits atop a fault line? No worries. “Seismic isolation is a method for isolating a structure from ground shaking due to earthquakes,”  Rensselaer Polytechnic Institute Professor Michael Symans explained.

Caught one of the shorter piers in its formwork stage, when the super crane made its first girder placement near the Rockland side nearly two years ago.

Because this is a cool photo . . . and yes, I’d like to know what you think.

One Large Section of Structural Steel at a Time

Have you seen the westbound span? Last week crews connected the main span and the Westchester approach, and this week they’ll connect the main span and the Rockland approach with a 375-ton section of structural steel.

Getting there!

I’d like to know what you think.
