The Gateway Development Commission (GDC) celebrated on September 28th the start of tunnel boring for the Hudson Tunnel Project. In the coming days, final testing will be completed and the first tunnel boring machine that will be used to build the new train tunnel under the Hudson River will begin digging. A second machine will launch soon after.
This historic moment marks the start of the first phase of tunnel boring for the Hudson Tunnel Project – the first new rail tunnel under the river in more than 100 years. It is the culmination of more
than a decade of planning and nearly three years of construction work.
The two tunnel boring machines launching this fall will bore approximately one mile through the hard rock under the Palisades Cliffs in New Jersey to the Hudson County Access Shaft on the
border of Weehawken and Hoboken. These two machines will be removed via the access shaft and replaced with a second pair of machines that will build the section of the tunnel under the Hudson
River.
The two hard-rock tunnel boring machines are expected to build roughly 30 feet of tunnel per day, including scheduled pauses for maintenance. They will reach the Hudson County Access Shaft
approximately one year after launching. The first phase of tunnel boring is being completed by Schiavone Lane Dragados JV as part of the contract for the Palisades Tunnel Project construction package. The Port Authority of New York and New Jersey (PANYNJ) is managing delivery of this construction package in partnership with GDC.
