The Gateway Program partners continue to advance with the engineering and design of the Hudson Tunnel Project with dozens of “geotechnical borings” to be conducted along the proposed alignment of the new tunnel in the weeks to come.

The exploration, which began in October and is expected to run through early 2020, will include 36 geotechnical borings covering both river- and land-based locations and extending to depths ranging from 55 feet to 280 feet, four seismic Cone Penetration Tests, a bathymetric survey in the Hudson River, and a surface-based geophysical survey along the Hudson Bergen Light Rail (HBLR) tracks in New Jersey.

The work is endorsed by GDC and is being implemented by Amtrak, consistent with Amtrak’s prior and ongoing support that it has provided for the Preliminary Engineering of the project.  The information gathered will help engineers better understand geotechnical characteristics of the Hudson River, New Jersey Palisades and the west side of Manhattan, reduce unknown subsurface conditions, and reduce project risk for future bids.
