Under the waterfront

posted by Jason Kottke   May 22, 2009

New York magazine reports on what lies beneath the water of New York Harbor, including $26 million in silver ingots.

The Hudson’s main current has, for all of recorded history, clung to lower Manhattan’s edge, skimming along the West Side. Battery Park City, built in the seventies, juts out into that flow, and since then, the current has been cutting a new channel, out toward the center of the river. That current is scraping mud off the top of the Lincoln Tunnel where it never did before; the underwater traffic tubes have lost 25 percent of their soil coverage in some spots. If the tubes ever became exposed, they would be at risk for shifting, cracking, and terrorist threats.
