Second TZ Section, this over Metro-North, Gone

You may recall when the first girder assembly was pushed over the Hudson Line train tracks to the first set of piersPhotos courtesy of New York State Thruway Authority.

This was followed by the second and third girder installations. Each time, Metro-North adjusted its schedule to accommodate the maneuvers.

Last Friday night, the super crane removed a second section of steel, this above the Metro-North tracks, and schedules were accommodated.

Such is the start of the changing view that will slowly evolve during the next year.

I’d like to know what you think.

Super Crane removes first section of Tappan Zee

Another moment in history: the super crane’s first lift in a year-long process of dismantling the Tappan Zee Bridge. One hundred thirty-three deck panels and two moveable barrier machines will be sent to nearly 12 state and local municipalities.

Twenty-nine months ago the giant crane lifted its first set of structural steel girders onto piers for the new bridge near the Rockland shoreline.

Below is a cross-section of the Tappan Zee Bridge’s Westchester approach span, a little like when someone cuts into a sheet cake and lifts out a precise piece.

Eight local munis and the New York State Department of Transportation (NYSDOT) asked for desk panels, valued at nearly $3 million including removal and delivery. Details here. Photos courtesy of New York State Thruway Authority.

Each of those panels — in use until last month —  is approximately 13 feet wide by 50 feet long, 8.25 inches thick and approximately between 75,500-86,500 pounds.

The moveable barrier system will head to the New York City Department of Transportation. To learn about the bridge that will slowly disappear, click here.

TBT: Going Vertical with Concrete Batch Plants

Today is six months since President Barack Obama was in town with Governor Cuomo, who visited Piermont last month. The Crane! The Crane! If you watched “Fantasy Island” years ago, then you’ll remember the opening scenes.

This machine is serious business. It’s being readied for what comes next: lifting pile and girder deck segments . . . and then dismantling the current bridge.

Realizing it’s not possible to see either the staging area or activity from the road, Team Outreach posted these photos and descriptions on the New NY Bridge Twitter page:

Pop quiz: If one plant can cast about 125 cubic yards of concrete per hour, how long will it take both plants together to make approximately 300,000 cubic yards of concrete for the new bridge?

When TZC president Darrell Waters told reporters the project was “going vertical,” this is what he meant.

Today’s sunny and clear weather is perfect for checking out the viewing area at RiverWalk Park.

Artistic Installations gather at Scarecrow Invasion

As I drove past this friendly group yesterday, I heard the introduction to Michael Jackson’s “Thriller” in my head. What a fantabulous line dance team it would be!

This lovely lady greeted me as she hung from one of the trees, floating gracefully in the breeze. And it was breezy! Kinda neat that the wind added to the atmosphere around 3:30 p.m. yesterday at Lyndhurst’s Scarecrow Invasion.

Met a powerful-looking figure who’s really very tame and friendly. A sign on one of his legs says high voltage and for authorized personnel only. The visible sign reminds all to drive slowly on the grounds and when driving past road work.

From its perch, this bird was deep in thought as it watched visitors walking by.

So much to see at this annual creative culmination of time, care and imagination.

Despite a danger warning, the friendly worker above didn’t object when your intrepid reporter posed for a photo next to him. Scarecrow Invasion is open at night starting October 19 through 31. Maybe some figures or their parts light up in the dark? Will be cool to see at night. Boo!

NOTE: If you visit the property after dusk to see the outdoor exhibit, then you will be directed to park on a flat level a good hike from the main drive.

I’d like to know what you think.

E’bound Main Span Steel, all Stay Cables in Place

Earlier this week, crews set the last section of main span steel on the eastbound span. Photos courtesy of New York State Thruway Authority.

You want numbers? Here they are:

The section was 24 feet long, adding to the more than 74 million pounds of all-American-made steel and concrete across the 2,230-foot cable-stayed part of the bridge. In case you were wondering, all 192 stay cables are now installed.

One more month, and bye-bye Tappan Zee Bridge drive. Eastbound traffic joins westbound traffic on the newly-opened span so the TZB’s landings can be demolished, and the eastbound span can be connected . . . because car-jumping from approach span to land is prohibited.

I’d like to know what you think.
