LANE WILL CONSTRUCT THE TWO PALISADES TWIN TUNNELS 

• Approximately 1.6 kilometers of twin tunnels will be constructed
• Two TBMs, giant tunnel boring machines, will be used for excavation
• The project is expected to be completed during 2027

Milan, August 22, 2024 – Lane, the US subsidiary of the Webuild Group, has secured a USD 466 million (€427 million) contract, with Lane's share at 35%, to construct two twin tunnels approaching the Hudson River in New Jersey, USA. These tunnels will significantly enhance New York City's rail connections. 
The project, known as the Palisades Tunnel boosting the efficiency and capacity of the region's transportation infrastructure.

This contract marks the first tunnel award given by the Gateway Development Commission (GDC) under the broader Hudson Tunnel Project (HTP), an investment to construct a new tunnel between New York and New Jersey and rehabilitate the over 114-year-old rail tunnel. The Palisades Tunnel is one of three separate tunnels, along with the Hudson River Tunnel and the Manhattan Tunnel. 

The project, also known as “Package 1A Palisades Tunnel Project,” involves the design and construction of two twin rail tunnels, each approximately 1.6 kilometers long with an internal diameter of about 8 metres. The excavation will employ two TBMs, large tunnel-boring machines. 

The contract covers the construction of the tunnel’s western portal near Tonnelle Avenue in North Bergen, six cross-connect tunnels, and a shaft in Hoboken, Hudson County. Designed to be 36 metres deep and nearly 37 metres wide, the shaft will be used to remove TBMs once the excavation is complete. Scheduled for completion during 2027, this project is a joint venture with Schiavone and Dragados. 

The Webuild Group is a global leader in underground excavation, boasting a track record of over 3,400 kilometers of tunnels. Beneath Lake Mead near Las Vegas, the Group undertook the “Intake 3 project” to replenish water supplies for the gambling capital of the world. This project involved the construction of a record-breaking hydraulic tunnel over 4 kilometers long, excavated 200 metres deep within the lake. On top of that, Webuild is currently advancing the Snowy 2.0 hydropower project in Australia by excavating a complex network of underground tunnels with innovative TBMs designed to handle significant gradients. The Group is also working on the Brenner Base Tunnel, which runs beneath the Alps between Italy and Austria. Once completed, it will be the world's longest underground railway tunnel, extending 64 kilometers, with the Innsbruck node integrated into its length.
