I-87+287 Tappan Zee and Cuomo Bridges over Hudson River

(Bridge Hunter, Satellite plus 152 photos)

The 1952-1955 cantilever truss bridge is being replaced by a $4-5 (depending on source) billion cable stay bridge.

(Update: RoadTraffic-Technology Cuomo article  "The average daily traffic on the old bridge was 138,000 vehicles, while the peak traffic was approximately 170,000 cars a day. The new Governor Mario M Cuomo Bridge will serve more than 140,000 motorists a day....The estimated investment on the new bridge is $3.9bn."

Old bridge:

The old bridge was built at the second-widest point on the Hudson , 3 miles, so that it would be just north of the Port Authority of New York and New Jersey so that the toll revenue would go to the newly created New York State Thruway Authority instead of the Port Authority. "A unique aspect of the design of the bridge is that the main span is supported by eight hollow concrete caissons. Their buoyancy supports some of the loads and helps reduce costs." It's 138' height above water is high enough to commit suicide. It has been referred to as the "Golden Gate Bridge of the East" because of the number of suicides. Several efforts have been implemented to reduce suicide attempts. [Wikipedia]

The buoyant caissons rest on steel piles driven to bedrock. The caissons were constructed on land and barged to the site. Some of the piles are 270' long because the bedrock was 300' below river bottom. The 30" steel piles were cleaned out and filled with concrete.  [NYCroads]

The main cantilever span is 1,212' and the total length is 16,013'. Avoiding the Port Authority was not the only reason for choosing the Tappan Zee location. The location was a crossroads of existing and planned expressways connecting New Jersey, New York State, New York City, and Connecticut. The 1,212' main span consists of 340' cantilevered spans and a suspended span of 531'. Each side span is 602' At the time of construction, it was the widest of its type. The 19 approach spans were 235-250' long, 93' wide, and 28' deep and weighed up to 900 tons. They were built on shore and then jacked up from a barge using four 500-ton jacks. [NYCroads]

It was designed to carry 100,000 vehicles on a peak day. During 1956 it carried 18,000 vehicles per day. Now it carries 135,000vpd over seven lanes, the middle one of which changes directions twice a day. It takes 45 minutes to change the lane. The projection for 2025 is 175,000vpd. [NYCroads]

None of the heavy rail (commuter), light rail, HOV+bus lane ideas considered during the design phase were incorporated in the final design. But it does have a dedicated bicycle and pedestrian span on the north side with scenic overlooks. [NYCroads, hdrinc]

I can't find where I read it, but since the demolition cost of the old bridge would be $140 million, leaving it as a walkway is being studied. A seven lane highway would certainly be wide enough for bicycles and pedestrians. In fact, they could add bus and HOV lanes on the north side.

Building the first Tappan Zee Bridge over the Hudson River, c. 1954. (American Bridge)

James Torgeson shared
In this 1954 view, ironworkers from the American Bridge Division of US Steel erect the first Tappan Zee Bridge, which crosses the Hudson River between Tarrytown and Nyack, NY. Although the river is very wide here, it is also relatively shallow, making it an ideal location for a long bridge. It replaced a ferry system and was in service until 2017 when it was replaced by the current signature span.
James Torgeson: This project was so large that several AB plants were involved, including Ambridge, Elmira and Gary.

It is being built by Tappan Zee Constructors.

In June, 2015, the first prefabricated section of three 12' tall and 400' long girders was lifted into place by the Left Coast Lifter. (video) This is the first of 31 miles of girders to build the first 4-lane, 3.1-mile bridge. A second bridge is being built in parallel so that each direction of travel will have its own 4-lane bridge. The girders are placed on pedestals on top of the pier cap. The pedestals "contain structures called 'seismic isolation bearings,' made of steel and a rubberlike material designed to offer some flexible movement (in case of earthquakes) and also to withstand the day-to-day pounding from trucks. The three-girder assemblages will soon be joined by twin-girder assemblages that will carry prefabricated electrical, plumbing and communications lines and complete the width of the span."

The 328'x100' Left Coast Lifter can lift 1,900 tons, and it came to this site through the Panama Canal. The Tappan Zee prefabricated sections weigh between 900 and 1,100 tons. The previous job for this "world's largest floating crane" was to help build the replacement of the earthquake-damaged eastern span of the San Francisco-Oakland Bay Bridge. The crane has three 806hp diesel powered generators to drive the cable winches. The 6,750 ton crane was built in 2009 near Shanghai.

The Left Coast Lifter has also been used to help rebuild Amtrak's Bridge over Spuyten Duyvil Creek.

In July, 2016, a crane boom collapsed across all of the lanes of the old bridge. Fortunately, no one was hurt. It was one of the 28 cranes working on the bridge. It was doing the routine task of installing piling using a vibratory hammer. Investigations did not have much to report three days later.  (Most pictures show the crumpled boom laying over the old bridge. This link shows the crumpled boom at the crawler base.) The crane was working on one of the 1000 piles needed by the bridge. A pile is a steel tube up to 6' in diameter and 300' long. But Jeff J. Loughlin, the business manager of International Union of Operating Engineers Local 137, had a theory. The Manitowoc MLC 300 crawler crane with a 256' boom was operating from the deck of the new bridge. Jeff's theory is "the pile had struck a very soft spot of river mud and had begun to sink rapidly, jolting the 60-ton hammer into a rapid drop and putting a particular strain on the boom, which buckled." He explained that with an old crane, the operator could take his foot off the break and allow the hammer to free fall and avoid stressing the boom. But modern cranes have a hydraulic braking system that limits the descent rate to 800 feet per minute. The operator had 30 years of experience manipulating cranes. I assume a drug test can be done within three days so that issue has been ruled out.

In August, 2016 the "halfway done" milestone was reached. This posting includes a slide show of eight pictures. The sixth picture shows how the roadway concrete is pumped from barges. Concrete plants were built on barges so that they did not have to run a lot of trucks through the adjoining communities. They also avoided long truck runs to build a 3-mile long bridge. The eighth photo shows the cranes and the blue form blocks that are raised after each of the 26 segments of a tower is built and cured. The cables vary in size from 11" to 24" in diameter with some of the biggest being 800 feet long.

In December, 2016 it hit the milestone of all eight 419' high towers being completed.

NYC CBS News has a list of its articles concerning the Tappan Zee.
Satellite image captured Jan, 2017 is probably at least two years old.
Satellite image captured Dec, 2017
I included the barges on the north side of the bridge because they are probably supporting the construction

I learned about this construction from some Facebook postings.

Manitowoc 4600 ringer Crane
Peter Cerniglia posted six photos with the comment: "Tappan Zee bridge in New York." The comments on the photos are my own.


3: This is probably one of the 60-ton hammers mentioned above that the crane crash described above was using.



4: During off hours they raise the tugboat assigned to the barge out of the water. I assume this is done to make it more difficult to steal or vandalize it. I've seen cranes around here hoist an air compressor in the air during off hours for the same reason.

Screenshot from the video on the referenced page.

Update: OSHA finds faulty equipment caused the Tappan Zee Manitowoc MLC300 crane collapse. It seems like a $13,000 fine for a $4 billion contract is barely a slap on the pinkie.

Chris Spence posted two photos with the comment:
got a Saturday in on new tappen zee bridge in ny, they added a 100' jib onto the 4600. She's got 400' of stick now
While looking for another bridge project in NY State, I found a highlights page with explanations of the various phases of construction and photos. One phase of note is that the 750 ton crossbeam between the towers was prebuilt and lifted as a unit by the "I Lift NY" barge crane.

The final girder assembly was placed in October, 2016.


The towers were completed Dec 2016 and the main span was connected to the approaches Feb 2017.

It is interesting how pictures float around the web and show up months later.

A few days after I found the NY Times article that they would not used "energetic felling," I saw a video of controlled demolition. It is interesting that they did not bother to remove the equipment on the deck over the left side before they blew down the span.
Sreenshot at -0:31 from video from share
If you scroll down in abc7ny you can access the above video without Facebook. If you scroll down even further, there is a video reporting that traffic will be shutdown on the new bridge during demolition. Around 1:30 on that video it explains why they switched from a plan to dismantle to a plan of controlled demolition: they discovered "structural issues" that invalidated the dismantlement plants.
This explosion even made it into the Chicago Tribune as a photo with a caption even though a local derailment and shutdown of the Heritage Corridor commuter service on 1/14/2019 didn't make it into the Tribune. (I looked hard for the CN derailment news.)

Chicago Tribune 1/16/2019, p15
An explosion from a demolition Tuesday brings down a section of the oldTappan Zeeo Bridge on the Hudson River near Tarrytown, N.Y. The bridge was operational from 1955 to 2017 and was replaced by a span officially named the Gov. Mario M. Cuomo Bridge. [The current governor's Dad, who was also a NY governor.] (Seth Wenig/AP)
FoxNews (source)
In addition to this still, the article include a "raw video" that allows you to watch the smoke blow away and zooms out to a wide angle shot. "State contractors used explosive charges to detonate vertical support columns on the eastern support portion of the bridge, sending the structure crashing into the Hudson River. A set of orange buoys on the water were connected to netting to help control the debris once it hit the water.
The steel from the bridge will be recovered by chains that have been laid on the riverbed, according to officials....The demolition had been set for Saturday, but it was postponed due to heavy winds. There are plans to dismantle the western portion without explosives sometime this year. Original plans called for the Tappan Zee to be removed piece by piece and avoid the use of explosives, which could have an impact on Hudson River fish habitats. Environmental experts, however, determined the old bridge was structurally unsound, preventing workers from continuing the piecemeal takedown." This article has a link to another article about the bridge being used to craete artificial reefs.
Darrell Colpo There was some issue with wooden pilings under the old bridge being slowly but surely being eroded by bugs, parasites because of where the wood comes from. They knew for a while it had to be replaced.

[If you scroll down in the article, there is a gallery of 46 photos of its construction. Even further down in the article is 62 photos of the demolition.]
