Earlier today, just west of Eleventh Avenue and just north of West Thirtieth Street
Lots of folks want to look at the action below; thus one must sometimes wait a few minutes on the High Line in order to get a chance to inspect the construction site.
The Gateway Program is projected to deliver nearly $445 billion in economic benefits from 2023 to 2060.
It’s a major infrastructure investment boosting jobs, productivity, and regional growth.
Improved rail service means better commutes and stronger business connections.
Long-term, it’s a game-changer for the Northeast economy.
The temporary support structures on the Portal Bridge arches are starting to be removed. The northern (and first) arch to be installed has had the temporary bracing removed, which means that the arch has had its cables tensioned and is capable of fully supporting itself.
Nice shot! Its not very often we get overhead looks of the bridge site. Looks like decking the arches is well under way and two sets of tracks are visible on the approach apans. The northernmost arch also is fully free of the temporary supports.
Got extremely lucky to get this - because 1 of the main runways at Newark is closed for maintenance all flights are landing on runway 28, which means if you are landing at Newark and on the right side of the plane you are making a right hand turn right around the bridge site. I also was in the middle seat so hopefully the person next to me didn’t mind
The tracks need some more ballast and they’ll be set. I also have heard rumors that the catenary will be constant-tension which should potentially alleviate some of the issues elsewhere where trains were ripping down the wires when it got hot out.
All the arch bracing beams are unhooked from the bottom half of each span as well, which means each arch is capable of supporting itself and the rest of the structure.
Another big milestone for the Tonnelle Avenue bridge is fast approaching: They’re setting up the molds for the concrete abutments at each side of the bridge. I cannot tell if they’re preparing the middle support column yet, as it’s impossible to see,e but concrete work is coming.
„ The Hudson Yards Concrete Casing – Section 3 (HYCC-3) Project is an essential rail right-of-way (ROW) preservation project on the west side of Manhattan that will enable the new Hudson River Tunnel to connect to New York Penn Station.
This project involves extending the existing concrete casing on a diagonal alignment from 11th Avenue to 30th Street, where it will link up with the new tunnel.
HYCC-3 will be approximately 500 feet long, 60 feet wide, and 60 feet high. Its structure will consist of heavily reinforced concrete ranging from 3.5 to 10 feet thick to support future loading from the overbuild platform. A waterproofing membrane will cover its perimeter.“

Will the tunnels also have a ventilation system near the Western Yards later on?
Yes. There will be a ventilation plant that will be built where they plan to either insert or remove the river TBMs on the NY side. There will also be one in the palisades where the hard-rock TBMs are removed.
The vent building for the new tunnel will be built on the west side/empty portion of the block south of HY Phase II, 30th St. It wont occupy the full empty portion of the lot, but they are currently trying to configure the best location for it in the lot for a future building to be built on top of it/ around it.
