    The Lincoln Tunnel, opened in 1937, is a multi-tube automobile tunnel that connects midtown Manhattan with Weehawken, NJ under the Hudson (North) river. To provide fresh air and remove dangerous car exhaust, three ventilation towers (two in Manhattan and one in NJ) exchange the air in the tunnels approximately every 90 seconds.

    Infrastructure is heroic.

    I didn’t notice the “Camera Use Prohibited” sign until it was too late. I guess their secret is out now.
