The Lincoln Tunnel is an approximately 1.5-mile-long (2.4 km) tunnel under the Hudson River, connecting Weehawken, New Jersey, to the west with Midtown Manhattan in New York City to the east. It carries New Jersey Route 495 on the New Jersey side and unsigned New York State Route 495 on the New York side. It was designed by Ole Singstad and named after Abraham Lincoln. The tunnel consists of three vehicular tubes of varying lengths, with two traffic lanes in each tube. The center tube contains reversible lanes, while the northern and southern tubes exclusively carry westbound and eastbound traffic, respectively.

A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is enclosed except for the portals, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
