Where the Bridge meets Water, Land and Itself

Above is one of the two 14-foot-thick foundations that each support four of the eight main span towers. Each foundation is 360 feet long and 60 feet wide and is filled with 11,000 cubic yards of concrete.

“Oh, East is East, and West is West, and never the twain shall meet.” Really?

This is kinda bridge-related since it intrigued us in a @NewNYBridge tweet.

Remember when we were stumped by what looked like a football helmet with stubs (looked like to me) sticking out of the sides (below)? Here’s where you can find this intriguing piece of art and much more.

You thought I forgot to write about current bridge news, right? To read what’s doing, check herePhoto courtesy New York State Thruway Authority.

I’d like to know what you think.

Educational Outreach explains the Pulley System

This cool interactive demonstration at Stemtastics in Larchmont showed kids and parents how pulleys work to lift weights like structural steel on bridges.

The I Lift NY super crane’s versabar (system) can lift up to 1700 metric tons (1928 US tons), much-needed strength when lifting pieces of structural steel.

It’s getting closer to when two-way traffic will shift to the the westbound span; however, I’m wondering how the belvederes will be constructed while cars are on that span. Will one lane be closed so crews can safely work on the shared use path? Will the belvederes be completed before traffic moves to the westbound span?

Here’s a view of the westbound span, where workers lower formwork over rebar. Getting there! Photos courtesy of New York State Thruway Authority.

Spring: it Really IS Peeking around the Corner

My cousin Russ grew up in New York and has been living on the West Coast since I don’t remember how long. Some years back he visited for a few days. A history buff, he suggested we suggested we see “Shackleton’s Antarctic Adventure” (2001). I wasn’t familiar with Shackleton and walked out of the theater amazed at his courage and determination. If you haven’t seen this seat-gripping film about his landmark expedition, then I suggest adding it to your list.

Big reach here: despite this winter’s bone-chilling temps the bridge project progressed, and classes that scheduled presentations these past few months often got more than they bargained for: outdoors, learning about the project where, right behind them in the river, crews worked despite the elements.

I don’t like cold and don’t take to it well; however, I make exceptions when the activity outweighs the weather . . . for an exciting day on the westbound span during the towers’ topping off ceremony in December. Whether you’re in the elements to work on the project or to visit it, bravo!

TBT: Looking Back at Earlier Project Photos

What are those things floating in the river? Debris? No, those are piles, and the story that day (June 2014 media tour) was pile cleansing: scooping out the muck prior to filling them with concrete and rebar (reinforced steel).

Did you notice the super crane is on the south side of the bridge? It had recently arrived at the project site, where crews waited for low tide a few days later before limbo-ing it under the current bridge.

Oh my, how tiny it looks at ground level. This is from early September 2015, when crews began building those now-419-foot tall towers using self-climbing jump forms. Are those cartoon heads in the red truck?

Here’s a memory from days gone by, when tolls were 50 cents each way. One-way collection was adopted August 12, 1970, and toll booths on the northbound lanes were removed.

And guess what? We made it through the Ides of March. Ha!

I’d like to know what you think.

Noise Barrier Installation Continues — & Lights

You know about the hour-long light show under the bridge last month, right?

TZC also connected the Westchester and Rockland approaches to the main span last month. Getting closer! I wonder where they’ll put this happy sign:

Crews continue installing concrete noise barriers chosen way back when along the southbound Thruway and the northbound side (next to the future shared use path) in South Nyack.

I’d like to know what you think.
