Last Piece of Tappan Zee floats in Hudson River

You can see the west anchor span floating atop barges in the river south of the new bridge and not far from its former location. The New York State Thruway Authority photo above is from last week; the former anchor now points south and not east.

It’s odd not to see a portion of the old bridge to the south of the new one; I was surprised to see the span still close by. Here’s a final look at the span next to the new bridge:

Today’s trip to Nyack and Nanuet was bookmarked by vehicles speeding across the westbound and eastbound spans at more than 65 miles per hour. There seem to be no way to enforce the speed limit unless police install those devices that measure speeds. It’s one way for the state to make money instead of increasing the tolls.

Something to think about. I’d like to know what you think.

TZB West Anchor Span Removal and Dismantling

Governor Cuomo was at the project site yesterday to document final removal of the Tappan Zee Bridge, whose east anchor span fell after a controlled demolition early this year. Now in the Hudson River, it will be lifted and removed.

While the old bridge became property of the design-build team, the state had an interest in how and when it was removed from the river. Last spring, the main span was lowered onto a bard and removed, and pieces of that span became part of the artificial reefs being built off Long Island.

The remaining west anchor span, attached by four columns, was cut and is being lowered onto barges, then moved south and dismantled.

TZB Demolition in Real Time & in Slow Motion

In case you missed the event yesterday as I did, here it is again in real time and in slow motion courtesy of Kevin P. Coughlin/State of New York. The section looks like it’s floating on the water; however, the perfect fall caused its columns to drop to the river bottom.

Demolition experts will place charges on vertical support structures along the span of the bridge. The charges are timed to detonate in a way that will safely lower the remaining structure eastward, away from the Hudson River’s main navigation channel, according to a fact sheet released by the construction project.

Fitting it happened this month: January 2013 was when the Thruway Authority issued Tappan Zee Constructors, LLC (TZC) Notice To Proceed.

I’d like to know what you think.

TZB Anchor Span falls via Controlled Demolition

Crowds had gathered since early this morning to watch the controlled demolition of the ironic Tappan Zee Bridge. The temperate was below freezing; still, this was not to be missed despite its occurrence on a weekday morning. I’m sure motorists were annoyed that the estimated 10 a.m. explosion occurred nearly one hour later and can only imagine waiting on clogged westbound 287 in Westchester and the equally clogged eastbound Thruway in Rockland.

The above photo courtesy of the New York State Thruway Authority shows the anchor span minutes after it fell into the Hudson River.

Demolition and salvage experts hired by Tappan Zee Constructors, LLC (TZC) were in charge of the procedure. Vertical members of the span fell so the team could safely lower the span away from the main channel using specialty marine salvage equipment, per a fact sheet. Material will be removed from the river during the following weeks by mMarine salvage experts; chains on the riverbed will remove the steel and support the salvaged structure, which TZC will place on barges and remove from the site.

I’d like to know what you think.

Prepare for delays when a controlled demolition will take down the eastern anchor span of what remains of the Tappan Zee Bridge this Tuesday morning.

State police will close Exit 9 (Tarrytown – Sleepy Hollow – Route 9), Route 119 in Elmsford and the Saw Mill Parkway (Exit 22) in Westchester, and Exit 10 (Nyack – South Nyack – US Route 9W) and Exit 11 in Nyack (Nyack – South Nyack – US Route 9W) in both directions at approximately 10 a.m.

Plan accordingly if you need to cross the river in either direction that morning.

I’d like to know what you think.
