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

2017+2018: (no Bridge Hunter)

[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.

[You can see the installation of the hydraulic jacks at both ends of the suspended span.]

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.
