“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.

I’d like to know what you think.

Eastern Anchor Span to be Demolished, Removed

Remaining Tappan Zee Bridge still a safety concern/EarthCam® construction camera

It’ll be equivalent of a set of fireworks in the Hudson River near Westchester next Saturday as Tappan Zee Constructors, LLC (TZC) conducts a one-time demolition and lowering of the Tappan Zee Bridge’s east anchor span on January 12 (next Saturday). Traffic on the Thruway between Exit 11 in Rockland and Exit 9 in Westchester will be halted for approximately 45 minutes.

No traffic will be allowed through the main span navigation channel for several hours; the Coast Guard will establish a 2,500-foot safety area around the procedure.

Did you hear it? Not the fireworks, the whoosh of time going by: January marked five years since the Thruway Authority issued Tappan Zee Constructors, LLC (TZC) Notice To Proceed on January 18, 2013.

In case you’re curious, the span is 672 feet long, weighs 6,500 tons and is 140 feet above the Hudson River. Materials will be recovered and removed during the next weeks.

Deemed damaged and stable “with certain key components highly stressed,” according to a TZC fact sheet, “the span has been closely monitored, and it has been determined that the original removal plan is no longer the safest method of removal.”

The contractor hired demolition and salvage experts to plan and carry out the 9:30 a.m. procedure. Vertical members of the span will fall so the team can safely lower the span away from the main channel using specialty marine salvage equipment, the fact sheet said. Marine salvage experts will remove the material from the river during the following weeks; chains on the riverbed will remove the steel and support the salvaged structure so TZC can place it on barges and remove it from the site.

Motorists, be aware the state police will close the Thruway at 8:55 a.m. for approximately 45 minutes. It will reopen after TZC determines the area safe for traffic. Metro-North schedules may be “only minimally affected.”

Residents will not be affected; key locations in Westchester and Rockland will be monitored for vibrations or air-blasts from the demolition, the fact sheet said. All construction activities and schedules are subject to change.

TBT: Three-Month Dredging Period Begins; Nautical Warnings Reiterated

From five years ago today. Photo courtesy of New York State Thruway Authority.

Yesterday opened the three-month (to November 1) window for dredging in the Hudson River, and today began round-the-clock operations.

“Excavation is in the shallow water to the east and west side(s) of the Federal Navigation Channel,” the Local Notice to Mariners reported. “Various barges are anchored outside the Federal Navigation Channel upstream of the bridge. On scene are the dredges WEEKS 506 & 551, tugs and barges that are lit; all are monitoring VHF-FM channels 13 and 16.”

It continued, “Mariners are urged to use extreme caution and transit the area at their slowest safe speed to create minimum wake after passing arrangements have been made.”

This information is reiterated in the Boat Owners Association of the United States’ East Coast Alerts by Mel Neale (August 1, 2013).

The chosen design requires less environmental impact regarding pile driving, dredging and threats to fish; the NYS DEC Final Permit, issued March 25, 2013, and additional Coast Guard information, are posted at the New NY Bridge website, which issued a press release today re operations and safety.

“Equipment associated with the operation is arriving on site. Approximately one dozen barges and other specially designed dredging vessels will be part of the operation,” the release said. It referred to the Coast Guard’s revised Notice to Mariners that details updated safety information, “including a request that boaters use extreme caution within 1,000 feet of all construction barges as a safety precaution.”

I’d like to know what you think.

First Steel Beam from TZB: new Marine Life

“We are stewards for a brief period of time on this earth then we hand it off to the next generation. And our responsibility is to hand if off better and we will,” Governor Andrew Cuomo said. “If you are a bridge, the afterlife is you still serve a purpose. You don’t go up, you go down.”

Holiday Weekend: Keep in Mind Boater Safety

There’s a silence to this photo taken from seven and one-half miles south of the bridges. One bridge nearly completed and one partially-dismantled bridge that was cause for celebration and dismay when it opened: another way to cross the Hudson River at irreparable cost to a village.

Recently, I heard stories about the Tappan Zee Bridge from someone who moved to the area as a child and who loved to swim in the river it crossed. It must have been fun way back then to swim in a clean river with keeping cool the only aims.

While the Hudson’s not for humans it is for boats (neat segue, right?) as Memorial Day weekend is the unofficial start of summer. I’ve been on the Hudson numerous times, thanks to this project. Never been on a sailboat or a small craft. Hint, hint, maybe an invitation.

Remember, the project is still an active construction site. Earlier this month, the main span channel was closed when crews removed the center section of the old bridge.

Have fun, be safe, obey the rules and keep all required supplies, including first aid, aboard. Enjoy!

I’d like to know what you think.
