Final Steel Truss Section of TZB is Now Gone

Another steel truss section of the bridge we will miss went bye-bye last week. The above photo shows the final section that was once underneath the roadway we used to drive on.

Although the trusses are barged elsewhere, one section of the old bridge’s steel cage can be recognized south of the new bridge. Crews are disassembling the 10-million pound, 532-foot section in the river.

While the super crane was dispatched to the Bronx to help Amtrak, it’s still on the project and will continue to help crews dismantle the Tappan Zee Bridge so the new bridge’s eastbound span, now one solid piece from Rockland to Westchester, can finally be finished.

I’d like to know what you think.

Last Steel Girder Installed on Eastbound Span

Let’s hear it for the cargo ship that passed our boat heading north less than half an hour after we left Haverstraw Marina. We heard these ships were seldom seen. Our luck to see one that day!

The 11-mile trip to the bridges was eventful and fun; however, things got going as we rounded Hook Mountain, and the bridges were in sight. It was “the bridges” because — although a shell of its former self — the Tappan Zee Bridge is there. A section of its main span missing was missing as it was prior to completion in the photo below, courtesy of the New York State Thruway Authority.

Its proximity to the new bridge made it difficult to photograph it from the same distance; however, it was possible to capture the same angle looking north.

For everyone who wanted to see the new bridge, there were many who wanted one last look at the Tappan Zee. Crews installed the last steel girder yesterday near Rockland, so now it’s possible to walk from one county to the other on the eastbound span.

Barge-based cranes will next dismantle section two (south of the opening), a cantilever truss weighing 4,560 tons; strand jacks will then help lower section three (closest to Westchester), an anchor span weighing 5,350 tons, onto barges. Crews will then dismantle section four (next to the opening) and lower section five (closest to Rockland).

The timetable for removing the remaining sections is unknown; however, July 20 is the last Historical Society of Rockland County boat tour.. For information, visit https://www.rocklandhistory.org.

I’d like to know what you think.

Disappearing from the River Piece by Piece

Looking as gloomy and sad as the weather, the Tappan Zee Bridge’s dissected main span glared at drivers or so it seemed. I was driving home in early afternoon after viewing the old bridge and its replacement from river level on a paddle wheeler. It was a treat made sweeter by a new hip joint that allowed me to painlessly walk around on both levels of our tour boat. And those were steep stairs!

The bridge that holds memories for many was rapidly shrinking and seemed small next to the eight main span towers and their supporting stay cables. Nearly two years ago, I penned a blog post that might have been what the bridge would have said if it could talk. The bridge. It will always be the bridge.

I’d like to know what you think.

Crews remove Center of Tappan Zee Main Span

Seven months after the final set of tires crossed the Tappan Zee Bridge, crews began removing the first of five sections from the cantilever truss structure’s 2,415-foot main span.

The process of dismantling and placing its 532-foot-long center span onto a barge began Monday evening. While boaters were advised the main span channel would be closed for 48 hours to accommodate the operation, the precise time for completion had not been determined at press time.

Eight hydraulic strand jacks lowered the 4,750-ton suspended center span onto a barge to be transported offsite for further disassembly. Two moveable barrier machines, no longer needed, and 133 deck panels removed at an earlier time will be sent to nearly 12 state and local municipalities.

Last November, Tappan Zee Constructors, LLC (TZC) and the I Lift NY super crane began the year-long process of dismantling the old bridge by removing sections of steel.

“This new bridge is a vital economic link for Rockland and the entire Hudson Valley,” Rockland County Executive Ed Day commented. “I look forward to the full opening of this modern crossing that has been long awaited by our residents.”

Westchester County Executive George Latimer called the new bridge “a symbol of innovation and technology. The Tappan Zee Bridge served our County well, but transportation needs have changed since it was constructed, and it is time for it to be taken down.

Both counties will benefit from the Lower Hudson Transit Link system that begins November 2018 and replaces Rockland County’s Tappan Zee Express buses.

During the coming months, crews will remove two main span sections via barge-based cranes. Strand jacks will assist with lowering the two anchor spans, after which the super crane will help remove the main span’s steel support structures, completing main span removal by late fall 2018.

“New York is leading the nation in rebuilding and reimagining our infrastructure so we can meet the demands of the fast-paced, 21st century economy,” Governor Andrew Cuomo said.

This milestone in the project’s development follows the opening of the new TZ’s westbound span August 26, 2017. Eastbound traffic shifted to that span six weeks later. The final set of commuter rubber met the Tappan Zee Bridge’s road deck at 10 p.m. October 6, 2017, when Nyack resident Seth Kestenbaum drove his restored 1929 Ford Model A across the span prior to its retirement.

Four lanes each of opposite-direction traffic on the westbound span will continue until the eastbound span opens later this year, when each span will each have eight general traffic lane — four breakdown and emergency lanes and dedicated bus lanes — in addition to space for commuter rail when funds become available and a bicycle and walking path.

“Infrastructure investments such as this are invaluable components of a vibrant state economy, and none are more important to our region than this new, more resilient and stronger crossing,” Tarrytown Mayor Drew Fixell noted.

“The construction of this new bridge will provide safe and more efficient travel for residents and visitors for generations, and I thank the Governor for recognizing the need to take action to replace the Tappan Zee,” South Nyack Mayor Bonnie Christian commented.

Design-build construction championed by the governor incentivizes the private sector to be creative on methods that speed up construction time and reduce costs and is used across New York’s large infrastructure projects, including the new Kosciuszko Bridge in New York City.

“The new bridge marks another step toward transforming New York’s infrastructure, reducing congestion for motorists and generating immense economic benefits for local communities, “ Thruway Authority Acting Executive Director Matthew J. Driscoll commented.

“(It’s) a great example of the state’s commitment to future generations of New Yorkers,” New NY Bridge Project Director Jamey Barbas agreed.

Crews begin removing Tappan Zee Main Span

This greeted the rising sun this morning. While the Tappan Zee Bridge’s consistent disappearance may not have bothered some, dismantling the main span meant the bridge-park idea was not going to become reality.

I don’t understand why the idea wasn’t stopped in its tracks because the old and new bridges occupy the same footprint and connection to the Thruway. How was that supposed to work?

Details about the main span dismantling in this week’s Rockland County Times.

I’d like to know what you think.
