Here in (USA) New York City & New Jersey area we have only 1 Train Tunnel Conduit bet. NYC & NJ for Amtrak & Other Trains -- another is desperately needed for many obvious Reasons !
* be advised this is major US Gov't Funded ( Biden Admin ' Infrastructure Act ' aka ' Build Back Better ' of All USA Old Crumbling Infrastructure's ( Bridges , Tunnels , Electrical Grids , Highways , Airports ) -- Current Biden Admin is Big on Pro Evironmental Issues & Renewable Green Energy Big Time !!!
** also Biden is Big Fan of Amtrak High-Speed Rail that Connects Multi-State Travel !
Here's the High-Level Particulars & Project Specs Summary::
Article Updated: The first phase of the Gateway Tunnel project begins next week on the New York and New Jersey side. The current structure is more than 110 years old.
In July, the federal government came through with a $6.88 billion grant.
Both states have also contributed and partnered with Amtrak.
Boring machines will plow through the muck to create structures for two tracks. That is a later phase of the work.
