The Palisades Tunnel Project will construct the first mile of the new tunnel tubes on the New Jersey side of the Hudson River.
The Palisades Tunnel Project is the first tunnel boring project of the Hudson Tunnel Project (HTP).
The project includes boring two parallel tubes approximately 5,100 feet long with an inside diameter of 25 feet 2 inches and six cross passages, as well as furnishing and installing a concrete tunnel lining with waterproofing membrane.
It also involves building the new Hudson County Shaft, which will be used to remove the tunnel boring machines (TBMs) when digging is complete.
Tunnel Boring Machines
The Palisades Tunnel Project will use two single shield TBMs. These machines will bore the two parallel tunnel tubes, installing the concrete tunnel liner behind them as they go. They will build approximately 30 feet of new tunnel per day.
The cutterhead of each TBM measures 28 feet, 8 inches in diameter, and the gantries stretch back roughly 500 feet. Each machine weighs 1,680 tons.

Upcoming Construction
See Our Progress
Construction of the Palisades Tunnel launched in August 2024. Today, the project has active sites in North Bergen and Weehawken. In North Bergen, the team is preparing the launch point for the TBMs, while further east they are building the Hudson County Access Shaft, where the Palisades TBMs will eventually be removed.
Tunnel boring is on track to launch from Tonnelle Ave. in North Bergen in 2026.
