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

In action: super crane connecting the Westchester approach and main spans/EarthCam®

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.

Checking in: Rockland Side of Eastbound Span

traffic

Driving home from Rockland Friday afternoon we were surprised to find the above eastbound. Turns out it wasn’t the “left lane closes, move over” indicator; it was a truck in the right lane that caused traffic shifts into the middle lane.

As traffic was stop-and-go, and I braked to a full stop every few minutes, I took the opportunity to seek and find the as-yet-unfinished eastbound span.

girder-1

My friend snapped the above photo of the eastbound span from the opposite direction. Getting there. You can see the westbound span right behind it.

I’d like to know what you think.

Westbound Main and Approach Spans Connected

final-girder

You had a fun weekend thinking about, then watching, the big game, right? My dad used to explain football to me every season, and by February I still didn’t understand the game. He grinned because I called it . . . well, that’s for another blog post.

If you think your weekend was exciting, then check this out: Tappan Zee Constructors, LLC (TZC) crews spent part of their weekend connecting the westbound main span with its Westchester approach span.

I watched as the super crane placed the first structural steel girders for the eastbound span in June 2015. Two months later it made another first for the westbound span, which was the center of attention this weekend.

Cool, huh? I’d like to know what you think.

Scenes from around the NNYB Project Site

ironworker

No fear of heights here for this ironworker at one of the new viewing areas.

main-span

This close-up view of the current main span with a miniature-looking truck reminds me of the MATCHBOX® Cars my brother had when we were kids.

pre-cast-deck-panels

Crews drive to the site now that precast deck panels are in place. ♪♫ I can see for mile and miles / I can see for miles and miles ♫ . . . well, 3.1 miles.

articulating-gantry

This interesting piece of equipment is an articulating gantry, project officials tell us, that rotates and can be mounted upside down, sideways or overhead. How can crews work safely on the new bridge’s underbelly? Here’s how.
