A joint venture between Tutor Perini and its subsidiary Frontier-Kemper Constructors has been awarded a $1.18 billion contract to construct the Manhattan Tunnel, a key preparatory component for the larger $16 billion Hudson Tunnel Project (HTP).

Key Project Details

• Scope: The JV will design and build 700 feet of twin, 30-foot-diameter tunnels from the Manhattan Bulkhead on the Hudson River to the Hudson Yards Concrete Casing.
• Purpose: This temporary tunnel shell will clear the way for tunnel boring machines (TBMs) to later excavate the permanent tunnel.
• Challenges: Construction will navigate major sewer lines, utilities, and underground obstructions, including archaeological finds, debris, and remnants of the collapsed 1973 West Side Highway.
• Technology: A protective digging shield will be used to keep most of the work underground.
• Timeline: Work begins in spring 2025, with substantial completion by 2029.

Hudson Tunnel Project (HTP) Overview

• Purpose: HTP will add a new twin-tube rail tunnel under the Hudson River from Secaucus Junction, NJ, to Penn Station, NY, and rehabilitate the existing 115-year-old North River Tunnel.
• Current Rail Bottleneck: The only rail tunnel under the Hudson carries 24 trains per hour but suffered extensive damage from Hurricane Sandy in 2012, requiring heavy maintenance.
• Economic Impact: The Northeast Corridor, from Washington, DC, to Boston, contributes 20% of the U.S. GDP, making this project critical to national infrastructure.
• Completion Timeline:
  • New twin-tube tunnel: Opens in 2035
  • Rehabilitated North River Tunnel: Opens in 2038

Additional Contracts

• In August 2024, a joint venture of Lane Construction, Schiavone, and Dragados won a $466 million contract to build the New Jersey-side section of the tunnel.

The Gateway Development Commission calls HTP "the most urgent infrastructure program in America."
