Tower Crane Removal; Structures Underway

Six months (brr!) ago the towers ceremoniously got their last cement pour, after which tower cranes began to remove the blue jump forms that helped build them.

The blue forms are a thing of the past, and recently the main span tower cranes said their goodbyes to the project. No longer needed, the second of two red tower cranes that helped construct the main span will soon be gone.

Instead of calling the driver in front of you names for crossing the solid line to get in front of you — HELLO. Other. Driver. It’s. A. Solid. Line. For. A. Reason. — look to the right (if it’s safe to do so). You’ll see additional concrete walls and formwork on the new maintenance facility in Tarrytown.

Here’s what it looked like yesterday per the New NY Bridge’s webcam. Near the top right (on the south side of the Thruway) are retaining walls and footing for the new state police facility.

I’d like to know what you think.

TBT: Changed View of Ever-Changing Scenery

I shall miss the sloping road above, whose replacement in an adding-the-final-touches photo, courtesy of New York State Thruway Authority, looks like this:

Will you miss it, too? I’d like to know what you think.

Walk/bike path: NNYB is asking what you think

At least something about the new bridge will be the same as the current one!

You know the westbound span will have a walking/bicycle path. Love it? Hate it? Think it was poorly planned? A way to enjoy the Hudson Valley? Wish it had more shade? (I do, I do.) Project officials want your thoughts via a Survey Monkey poll.

“The New NY Bridge project team is seeking your input to better understand how the community will utilize the new Shared Use Path (SUP) to be built on the westbound span following completion of the eastbound span in 2018. Features of the bicycle and pedestrian path will include six overlooks—or resting points—above the Hudson River; visitor parking and pavilions; and interpretive exhibits, art, and signage.”

Here’s your chance to tell all! They’d like to know what you think.

Schools were closed when the new bridge opened

Besides having a clear day for the Historical Society of Rockland County’s river tour last week, I had the pleasure of sitting at a table with several people who are working on the new bridge.

They preferred I not mention their names. I agreed to respect their privacy and asked about their responsibilities and how they felt about working on the project and seeing it from this perspective.

One gentleman told me his father was an ironworker on the original Tappan Zee Bridge and said his son and grandsons are employed on the current project. “Four generations working on the bridge,” he smiled.

He lived in Piermont in 1955 and remembers walking across the new structure when it opened. “The governor drove across the bridge, and I didn’t have to go to school that day. Everybody was walking across the new bridge, and schools were closed.”

Detailed bridge update and photos are in this week’s Rockland County Times.

I’d like to know what you think.

Students Learn Valuable Lesson at Presentation

Eleventh and 12th grade physics classes at Byram Hills High School got a peek into the state’s largest infrastructure project when the New NY Bridge educational outreach team came to their school this academic year. “We asked them to focus on the engineering aspects of it although some science students were there,” BHHS teacher Paul Beeken said.

The presentation included the politics of getting a megaproject started. “One fascinating concept for us (students) was how to get a project like this in place,” Beeken said.

This year one of BHHS’s classes built a truss build from balsa wood and was challenged to see how much it can carry versus the weight of the bridge itself. “With this in mind, they have an understanding it’s a tradeoff: cost of materials and how heavy is the bridge versus how much can it carry,” he said.

Beeken requested the presentation focus on engineering and the stress factors: what goes into building the roadway, the technologies needed to lift roadway and how the super crane was able to lift the weights it did as he’d finished a unit on forces including weights and pulleys.

When the kids asked Marcy where he got his degree, he told them he’s not an engineer and explained his background. “That was very valuable,” Beeken said, “because the kids could see someone who wasn’t an engineer but who was still very articulate about all the different facets of the project.”

Engineering is only one part of the project, he noted. “While maybe one-tenth of the class will become engineers, it’s important to have a basic literacy to more easily navigate the subject.”

“Before the (Tappan Zee) bridge was built there was nothing there, so no one had any expectations about what a bridge would do,” Beeken said. “Now (building a bridge today) is 10 times more difficult because people need that bridge and depend upon it. You want to build a new one, so the logistics of being able to build a new bridge without ever shutting down the old one presents challenges.”
