Some great new angles now available! A 24/7 view here:
And on the tunnel box as well!
The camera on this side is nicely placed on top of the secant piling giving us a great view of the project.

Looks like more segments of the TBM are being assembled. It seems the parts are being moved to the tunnel box area where the crane is assembling them. There is another segment that is on the other side of the bridge. Because assembly is starting on the left tube, this is the tube that will be dug first.

The New Portal Bridge is visible from the NJ Turnpike, and it’s looking really good. The bus window was dirty, so it’s kinda hazy.

Is my understanding correct that another identical looking bridge is getting built just in front of that? (For the other direction?)

Yes Portal Bridge South will have 2 additional tracks. I don’t believe there is funding at the moment but it’s ok because a few things need to be built first (the new Hudson tube, the rehab of the current one, etc) for the capacity to be necessary.

There is no funding allocated for a Portal South Bridge at this time. Even if there was, they wouldn’t be able to build it until the old Portal Bridge is demolished anyways.

There’s a lot more going on at the various Gateway sites.
Per their official newsletter, excavation of the Palisades shaft is now underway, with the retaining wall work now complete.
Here’s all the upcoming excavation work at the Palisades shaft.
Elsewhere, ground stabilization is moving to the second-to-last position, and the HYCC3 has almost all the floor and wall work complete, and emphasis is shifting to pouring the roof.
There is also now a page on the NJ Surface Alignment, which includes a bunch of diagrams and renders.
Back at the tunnel site, the third TBM segment was finished and moved into position. With that, excavation on the remainder of the tunnel box is continuing, with the temporary embankment for pile installation fully removed, and work on a 4th TBM segment is starting.
Additionally, a new support structure for the TBM is being assembled.

from Sunday, looking southwest from 11th ave. believe this is the sand packing to create the roof of the connecting tunnel? (I was a little tipsy after brunch and a local festival.)

The sand packing is a part of the process to cast roof sections of the tunnel. In your last picture, you can see parts of the mold used to shape each section.

Time for another Tunnel Box update: excavation of the remainder of the box is continuing, and excavators in one area are already below ground level.
The 4th TBM segment has been completed and is now connected to the finished segments. The 5th segment is the next portion to be put together. Once the 5th segment is complete, I expect work to slow down for a bit since there is limited room for continued assembly.
The Hudson County shaft is actually starting to resemble a hole in the ground as well.
Per the latest project notice from June 15, the initial pit will be 12 feet deep, and the cap beam that secures and supports the shaft walls will be installed. From there, work will progress to dig the remainder of the pit, reaching a depth of up to 150 feet.
Moving on to the Manhattan shaft, trenching for utility relocation is taking place overnight to enable excavation to continue.
It also appears that all the actual slurry walls were installed, as the equipment used to dig the trenches and inject the material has been removed. It appears the top rim is now being prepared to be installed.

Another fantastic update @ALC11 !

The plan is to reconstruct the 2 current tunnels only after these are operational right?

Yes. Once the new tunnels go online, the old tunnels will be renovated, one at a time, so at least 3 tubes remain operational as they are restored.

Like the ERT project? Sounds good to me. Can’t wait until all of this is online. Amtrak is already posting record high ridership, once these big projects on the NEC are up and running it should skyrocket.
More important than that though is the increased reliability of the tunnels so people can get in and out on time
