The Gateway Program involves a $16 billion project to construct a new Hudson River train tunnel, aimed at replacing aging infrastructure and preventing Northeast Corridor collapse. Construction has begun with tree removals and planned median elimination along the West Side Highway, prompting significant traffic shifts. Ground freezing will stabilize the riverbed for excavation. Cyclists on the Hudson River Greenway will face detours. These disruptions are anticipated to continue until early 2027, with the tunnel not opening until 2035, affecting commuting patterns significantly.
To prep for tunnel excavation under the Hudson River, crews have already chopped trees near 30th Street and plan to remove the median on the West Side Highway next.
Crews will insert giant pipes that pump cold brine into the soil, essentially creating an underground popsicle to prevent soil collapse.
Disruptions are expected to last through early 2027, with the full tunnel not scheduled to open until 2035.
The eventual plan is for trains to emerge from the new tunnel, located just east of the highway and link up with the Penn Station tracks under Hudson.
