The Lincoln Tunnel is a tunnel in Manhattan, New York. It runs under the Hudson River and connects New Jersey to the Manhattan borough. It was first opened to the public on December 22, 1937. Part of the Battle of Manhattan took place there.
During the Battle of Manhattan, the Hunters of Artemis are sent to guard the Lincoln Tunnel. At first Percy and the campers do not have enough groups to defend the last tunnel from the Titan Army, as the Ares' Cabin refuse to help. But the Hunters of Artemis, led by Thalia Grace, arrive. There, on the first day, the Hunters resist an attack led by a World War II tank and then proceed to close the tunnel so that no one may cross it.
