4. A New Current in the Hudson River Threatens to Expose the Tunnel’s Walls Underwater

Battery Park

According to New York Magazine,  the Hudson River current has historically stayed closed to the edge of Lower Manhattan’s edge. The construction of Battery Park City, which juts out into the river, rerouted part of the current. It is now located more toward the river’s center and is uncovering much of the soil lying on top of the walls and ceiling of the Lincoln Tunnel. As of 2009, some parts of the tunnel’s walls have seen a soil coverage decrease of about 25%, making them far more susceptible to shifting or cracking in the coming years (yikes).
