Girders and Concrete make News this Week

Here’s a close-up of one of section of the approximately 50,000 tons of structural steel on the 196,416-inch long bridge’s approach spans. Above is the Westchester side.

They’re huge. HUGE.

Imagine seeing one of the six barges that accidentally came loose after last week’s storm and floated down the river to a town or village, maybe near you.

This week, crews will be installing them on the eastbound Rockland approach span using mobile cranes. The I Lift NY super crane gets to sit on the sidelines for this job.

Lots of concrete pours in the works, too, for the eastbound span’s abutment in Rockland and for the new state police facility in Tarrytown. Work continues on the Thruway Authority’s new maintenance facility.

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.

I’d like to know what you think.

Boater Safety Rules for the Bridge Project Site

You know boating near the project site is restricted and dangerous, right? Not watch-out-for-sharks dangerous yet close to it. (Pity the kayaker above!)

From the New NY Bridge website:

• Stay clear of all overhead work and maintain a safe distance of 1,000 feet from all construction equipment and support vessels.

• Use the center 600 feet of the Main Channel (when available) to navigate in a north-south direction with no wake at a maximum speed of five knots.

• All bridge piers and abutments are protected by a 25-yard security zone.

• No unauthorized vessels are allowed in the Safety Zone surrounding 16 construction barge mooring locations. Lighted buoys mark the zone and mooring locations.

• Regulated Navigation Areas (RNAs) stretch 500 yards north and 500 yards south of the existing bridge. No vessel may stop, moor, anchor or loiter within the RNAs.

• The Eastern RNA will be extremely active and vessels transitioning to and from the eastern shoreline at Tarrytown should approach and depart to the north. The Western RNA will be impassable at times and mariners should stay clear of the area.

• Lighted channel markers provide recreational boater access to the Piermont waterfront.

• Construction barges and other vessels on the site are being tracked by GPS technology.

• TZC will monitor Marine Radio Channel 16 to communicate with boaters.

The New York State Thruway Authority provides this information as a public service. Any reliance you place on such information is therefore strictly at your own risk. Nothing in these guidelines shall supersede the actual construction conditions, and regulations set forth by the U.S. Coast Guard.

Watch out for fins in the water! I’d like to know what you think.

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.
