Throwback Thursday: Deck Panel Installation

This time last year:

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.

Happy Anniversary to Six Years of Blogging

They look so close to each other, stay cables and the cantilever truss structure. That’s what I thought driving home as cars well above the speed limit passed me.

The day was a break from a difficult week, a chance to disconnect temporarily. I’ve been covering this project for the past seven years, blogging about it for six, and sometimes include personal posts. I need to write, It keeps me going.

Seeing President Obama, even from afar, when he came to Tarrytown five years ago, was a highlight as were watching the super crane place the first steel girder assembly and walking on the westbound span opening day ceremonies and freezing my bum during the topping off ceremony for the main span towers.

And the boat trips and umpteen photos and meeting the governor who, initially surprised and maybe wondering what the gutsy reporter walking toward him would ask or say, was friendly and seemed relieved no questions were asked. It was my intent to introduce myself, and as he stood there alone, I took the opportunity.

A favorite souvenir is the tiny, heavy sample from the new structure that keeps the papers on my desk from rearranging themselves when the window’s open.

I’d like to know what you think.

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.

Final Steel Assembly & Removing TZB Roadway

Last week (April 12), the super crane placed the final steel girder assembly on the eastbound span. Crews continue placing additional small, unattached girders near Rockland so the span will connect to land.

The I Lift NY has been installing the blue steel assemblies since June 2015. I was there and saw the massive crane lift the first blue steel assembly from the barge that brought it downriver. Very exciting!

As the super crane ceased work on the new bridge, it will remove sections of the TZB’s large steel truss during the coming week; they’ll be placed on barges and eventually recycled.

I’d like to know what you think.

Westchester Landing Removal & Lane Closures

And away it goes! Sections of Thruway near the Westchester landing say goodbye to the land this week, when crews begin removing them to make way for new precast concrete slabs. Click here for information about lane closures this week.

This is how the Thruway will connect to the land . . . and another reason the floating Tappan Zee Bridge-park was not a good idea.

Back to the picture above. Wouldn’t it make a pretty desktop wallpaper for your laptop or computer? Do you recognize the pattern?

It’s a tiny area of the more than 100,000 tons of welded (structural steel) beams supporting the roadway. Photo courtesy of the New York State Thruway Authority.

Oh, and remember the article I mentioned earlier about infrastructure, the new bridge and federal spending? You can read it here.

I’d like to know what you think.
