The Lincoln Tunnel is a 1.5 mile-long tunnel under the Hudson River, connecting Weehawken, New Jersey with New York City.

The first tube was built in 1934, and additional tubes were added in 1945 and 1957. The three tubes carry six traffic lanes in total. During the morning rush hour one traffic lane is used exclusively by buses.

The Lincoln Tunnel carries about 120,000 vehicles per day making it the busiest vehicular tunnel in the world.
