The Port Authority is working on a hush-hush project to terror-proof the four PATH subway tunnels running under the Hudson River to thwart a potential catastrophic bombing that could flood the system, The Post has learned.
Defense contractors — toiling in the cloak of darkness — are installing reinforced metal plates along the interior walls of the tunnels, and massive flood-prevention gates are being erected at either end of the two main lines that run from the World Trade Center and the West Village to Jersey City, sources said.
The flood gates are designed to close off one or more tubes should water come surging in. That would protect other parts of the PATH system and its riders, which number about 250,000 a day.
