Work Done, Super Crane departed Project Site

It arrived with great fanfare five years ago and left quietly last weekend. Its work on the project completed, the I Lift NY headed downriver accompanied by three tugboats. The photo below is from a video captured by Felice Ehrlich.

Some stats:

Its lifting Capacity is 1,929 tons, and its boom length is 328 feet. It raised 140 steel girder assemblies, four main span crossbeams, and 120 road deck panels.

First lift was April 2015
Placed first girder in June 2015
Removed first section of TZB in Nov. 2017
Final lift was May 2019

Click here for super crane history and trivia and here for more project details. Curious as to why it had three tugboat escorts.

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.

Final Steel Truss Section of TZB is Now Gone

A tugboat with a steel truss section of what was once the Tappan Zee Bridge/NYSTA

Another steel truss section of the bridge we will miss went bye-bye last week. The above photo shows the final section that was once underneath the roadway we used to drive on.

Although the trusses are barged elsewhere, one section of the old bridge’s steel cage can be recognized south of the new bridge. Crews are disassembling the 10-million pound, 532-foot section in the river.

While the super crane was dispatched to the Bronx to help Amtrak, it’s still on the project and will continue to help crews dismantle the Tappan Zee Bridge so the new bridge’s eastbound span, now one solid piece from Rockland to Westchester, can finally be finished.

I’d like to know what you think.

Last Steel Girder Installed on Eastbound Span

Rare sight was a cargo barge heading north on the Hudson River/© Janie Rosman 2018

Let’s hear it for the cargo ship that passed our boat heading north less than half an hour after we left Haverstraw Marina. We heard these ships were seldom seen. Our luck to see one that day!

The 11-mile trip to the bridges was eventful and fun; however, things got going as we rounded Hook Mountain, and the bridges were in sight. It was “the bridges” because — although a shell of its former self — the Tappan Zee Bridge is there. A section of its main span missing was missing as it was prior to completion in the photo below, courtesy of the New York State Thruway Authority.

Its proximity to the new bridge made it difficult to photograph it from the same distance; however, it was possible to capture the same angle looking north.

For everyone who wanted to see the new bridge, there were many who wanted one last look at the Tappan Zee. Crews installed the last steel girder yesterday near Rockland, so now it’s possible to walk from one county to the other on the eastbound span. Photo below courtesy of the New York State Thruway Authority.

Barge-based cranes will next dismantle section two (south of the opening), a cantilever truss weighing 4,560 tons; strand jacks will then help lower section three (closest to Westchester), an anchor span weighing 5,350 tons, onto barges. Crews will then dismantle section four (next to the opening) and lower section five (closest to Rockland).

The timetable for removing the remaining sections is unknown; however, July 20 is the last Historical Society of Rockland County boat tour.. For information, visit https://www.rocklandhistory.org.

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.
