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.

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.

“Tappan Zee Constructors (TZC) has rescheduled the controlled demolition of the old Tappan Zee Bridge’s east anchor span for Tuesday, January 15, at approximately 10 a.m., weather permitting,” the contractor said in a statement this evening.

In response the contractor rescheduling plans to demolish the eastern anchor span of the Tappan Zee Bridge this coming Tuesday, Jan. 15, at approximately 10 a.m., crews will begin to close entrance ramps.

In Westchester: Exit 9 (Tarrytown – Sleepy Hollow – Route 9), Route 119 in Elmsford and the Saw Mill Parkway (Exit 22)

and in Rockland: Exit 10 (Nyack – South Nyack – US Route 9W) and Exit 11 in Nyack (Nyack – South Nyack – US Route 9W).

The Coast Guard will establish a 2,500-foot safety area around the procedure, and the main span navigation channel will temporarily close from 8:30 a.m. to 11:30 a.m.

“TZC continues to work with local, state, and federal agencies on the controlled demolition and the subsequent operations to remove the steel from the Hudson River,” the statement said. The contractor is coordinating with Metro-North regarding Hudson Line trains; see schedule here.

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

“Tappan Zee Constructors, LLC (TZC) postponed Saturday’s controlled demolition of the old Tappan Zee Bridge’s east anchor span due to inclement weather,” the contractor said in a statemnet. “The sustained winds caused delays to the preparatory work of the planned demolition operation. Once we have rescheduled the operation we will provide an update.”
