Lincoln Tunnel [SEP] Introduction
The Lincoln Tunnel is an approximately tunnel under the Hudson River, connecting Weehawken, New Jersey, to the west with Midtown Manhattan in New York City to the east. 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. The Lincoln Tunnel was originally proposed in the late 1920s and early 1930s as the Midtown Hudson Tunnel. The tubes of the Lincoln Tunnel were constructed in stages between 1934 and 1957.
