We seem to have lost another truss bridge to two cable stay bridges.

[Note the long approaches to get the needed 140' shipping clearance are significant bridge structures in themselves. Actually, the clearance mid-span is 138.5' minimum @ MHW. [panynj-facts] I assume MHW is Mean High Water.]

As one would expect with a cantilevered truss, the suspended span was lowered to a barge.

Rob McGrady I would love to take an aerial shot from the helicopter just to show how many cranes we have in that small area lol
[A comment observed how the shot shows how long the tracks are on the 12000 that is straight down.]

"Because the site is just a few miles from Newark Liberty International Airport, maximum tower height was 272 ft, which drove unusually shallow cable angles. A unique anchor box shaped like a saddle allowed the cables to be stacked more tightly than a traditional anchor box, increasing the stay angles. It also allowed for the anchor boxes to be placed on the outside facing the towers, which allowed Parsons to keep the profiles for the towers slender.
'None of the steel fabricators would even bid on it until we printed a 3-D model,' Seth Condell, design manager for Parsons, told Roads & Bridges."

After a four-year construction process, the new Goethals Bridge linking New York and New Jersey is officially open. The new $1.5 billion twin-span cable-stayed bridge replaces the original bridge built in 1928. The Port Authority of New York & New Jersey and design-build team Kiewit-Weeks-Massman, AJV relied on EarthCam’s panoramic cameras and portable Mobile TrailerCam solution to document the complex process, which can been seen with EarthCam’s new 4K construction time-lapse movie.
|safe_image for New Goethals Bridge Set to Open to Traffic on Monday [posted May 21, 2018]|
Both spans of the new Goethals Bridge that connects Elizabeth, NJ, and Staten Island, NY, are now open. Late Sunday evening, the westbound bridge opened to traffic. The eastbound bridge has been in service since June 2017.
New Jersey Gov. Phil Murphy said: “The completion and opening of the second span of the Goethals Bridge project represents one of the most important infrastructure enhancements undertaken in the New Jersey-New York metro region in more than eight decades.”
Congratulations to our project team and joint venture partners for their hard work on this project.
[The towers were dirty before the bridge was done being built?]

Our Goethals Bridge Replacement project was named ENR New York's Project of the Year. Congratulations to the Port Authority of New York and New Jersey and the entire project team.
[The article describes how they handled the tower height limit of 272' and the requirement that they slant outwards. The design anticipates adding a mass transit lane in the middle between the two spans.]
Massman's project web page contains five photos with the comment:
This project for the Port Authority of New York and New Jersey is part of a 40-year, $1.5 billion design-build-finance-operate-maintain contract. The joint venture will design and build the project and turn it over to the developers in early 2018 for them to operate and maintain the structures for the remaining 40 year term. The existing bridge, which was built in 1928, was the Port Authority’s first bi-state project and is named after Major General George Goethals; a builder of the Panama Canal and first consulting engineer for the Port. The new 1.4 mile long twin structures, with their 950-foot long main spans over the Arthur Kill tidal strait, will carry three lanes of traffic each way between Staten Island, New York and the City of Elizabeth, New Jersey. This project will provide pedestrian and bicycle access for a safe, scenic passageway as well as contain state-of-the-art smart bridge technology for improved incident response times. The twin structures are also designed to allow for future mass-transit lanes between the bridges when needed in the future.
