Flashback Friday: Two Years Ago Today

early-august-2016

This photo was taken in early August, when the towers were nearing their eventual heights. The new bridge is more even (less grade) so trucks won’t have to do what my neighbor calls “stop for air,” referring to their use of air brakes and shifting as needed on the current bridge.

You see a construction vehicle, right? Now look closely at what’s ON it.

Crews continue removing the self-climbing forms that helped build the main span towers during the past 15 months. They’re driven off the bridge — the westbound span is connected to land — to be repurposed.

I’d like to know what you think.

Lots Happening Today Locally and Nationally

This time last year it snowed. Today students locally and across our nation will be protesting Congress’ inaction about gun control. And today is Pie Day.

Here’s a neat photo. 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.

Here, another view of deck panels to be installed, at the Westchester landing.

Pick a size, the right size. Adjustable bars are suited for the weight/size objects they’re required to place on the new bridge. Photos are courtesy of the New York State Thruway Authority.

I’d like to know what you think.

TBT: Main Span Towers’ Topping Off Ceremony

It’s Throwback Thursday, and you know what that means: this time last year, media had an exclusive, first-time look at the new westbound span. I’ve said at earlier times and repeat, the project is colorful: the I Lift NY, bright blue structural steel girders, red and yellow cranes, blue jump forms, yellow guard rails.

Governor Cuomo braved freezing temps without gloves, hat or scarf during the topping ceremony for the new bridge’s eight main span towers.

I looked at the stay cables tensioned under the main span and the girders peeking out from under the Westchester approach, where we stood, and at the rebar along the northern side of what would eventually be the shared use path and at the jump forms atop the towers and at the road deck built east from the main span (built west, too, that we couldn’t see).

The photo to the right — one of the towers with stairs leading to the top — got me thinking about how nervous I was in high school gym class if the teacher asked us to stand on the balance beam or sit on the lower of two uneven parallel bars.

Last year was an experience, surpassed only by the opening ceremony this past August.

I’d like to know what you think.

Bridge Progress and Four Years in Two Minutes

Taking a look back two years ago when the main span towers were beginning. Here are the past four years in two minutes courtesy of the project team.

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.
