Concrete Pours continue on Soon-to-Open Span

Remember these? They’re deck panels at the Westchester landing months earlier. The same way kids’ toys interlock, these hairpin reinforcing steel bars connect deck panels to each other. Reinforcing concrete will be poured between the spaces (around the steel) prior to the final driving surface. Photo courtesy of the New York State Thruway Authority.

The other day someone asked me why the Tappan Zee Bridge couldn’t be used as a bridge park. One look at the section below from the same photo will answer his question.

People ask why the Tappan Zee Bridge cannot become a bridge park. The reason: no way to connect it to land /Kevin Coughlin/Office of Governor Andrew M. Cuomo

You can see that the new westbound span and in-progress eastbound span are connected to the Westchester landing, and the piers of the Tappan Zee Bridge are hanging out in the river. How would people access the bridge park if there’s no connection to land?

Westchester and Rockland have plenty of beautiful riverside parks to enjoy. I disagreed with the idea for a bridge park, namely for safety and lack of feasibility. There’s a way to enjoy the river view from the new bridge when the side path opens in 2019.

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. 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.

Sight Unseen: Activity Beyond the Car Windows

No fear of heights for whoever took the first two photos in this blog post or the above view of structural steel connecting the unfinished eastbound span to the Westchester landing. Photos courtesy of the New York State Thruway Authority.

After structural steel comes concrete deck panels. More than 6,000 precast ones, including those you and I drive on, have been placed so far.

You won’t see this from the road: the top view of a concrete barrier form that’s filled with steel rebar, which reinforces everything concrete on the new bridge.

Lots of progress on the Thruway Authority maintenance building, in final design. Maybe you missed this while driving by as we know your eyes were on the road.

The new barracks for state police is also shaping up on the Thruway’s south side.

I’d like to know what you think.

Soon to be Gone: TZB Main Span Removal Ahead

You can see the future in these photos; the two below are courtesy of the New York State Thruway Authority. It’s getting close to that time, folks, when the Tappan Zee Bridge will cease to be yet will remain forever a part of the area’s history.

There is it, that cut in the main span truss. Good to know parts of the bridge will be repurposed to state and local municipalities; a little eerie to realize this day, so far into the future nearly six years ago — during my first bridge meeting at the Quay Condominium in Tarrytown — would finally arrive.

Seven months ago, the last car drove its 3.1 miles. The ginormous crane returns to help crews remove sections from the bridge’s main span. Moving forward, they continue to installing precast concrete deck panels near the Westchester landing and pouring concrete there.

Yesterday was eight miles. It’s more than three miles one way and the same walk back or there’s the Lower Hudson Transit Link.

I’d like to know what you think.

Eastbound Span Increases as TZB Decreases

This photo showing the angle we see from the other side (while heading west) is straight from the project’s newest tower webcam via EarthCam® construction cameras. If you click the photo, then you can see the I Lift NY setting structural steel near the Westchester shoreline.

Been a while since I posted: while I was away getting a new hip joint, the super crane’s been busy! Last weekend it was installing deck panels on the eastbound span so that you and your vehicle will have a safe ride. President Barack Obama and Governor Andrew Cuomo both talked about holes in the Tappan Zee Bridge’s roadway.

“At times you can see the river through the cracks of the pavement,” Obama said during his May 2014 visit to Tarrytown. “Now, I’m not an engineer, but I figure that’s not good.”

“They keep doing these patch jobs on the Tappan Zee Bridge, including those very heavy metal plates over holes in the Tappan Zee Bridge,” Cuomo said during remarks to the North America Building Trades Union’s Legislative Conference in April 2016.

“And when you go over the heavy metal plates, you see the truck in front of you bounces just a little bit, and then you see a little light coming through from the corner of the plate,” he said. “I would always take my seat belt off when I was going over the Tappan Zee Bridge. I was getting ready to swim, I would take off my shoes, and I would open the window. I was ready.”

In the above photo, courtesy of the New York State Thruway Authority, cranes are installing said deck panels. They’ll be interlocked via their hairpin reinforcing steel bars, after which reinforcing concrete will be poured between the spaces (around the steel) prior to the final driving surface.

Enough excitement for now. Check back later for another blog post. Self-promo: my article about infrastructure, the new bridge and federal spending will go live next month in a national magazine.

I’d like to know what you think.
