The Library of Congress just added a whole slew of old New York Tribune covers to their Flickr account. This one caught our eye: an underwater boulevard connecting Brooklyn and Staten Island! The cover read: "Now for a boulevard under the sea... Ambitious plan for a tunnel 100 feet wide and 10,000 feet long, easy to approach at either end for vehicles of all kinds, and calculated to keep commuters within city limits instead of letting them get away to Jersey and Westchester." View the full cover after the jump; the edition is from September 18, 1910. Also of note: this proposed new thoroughfare to relieve traffic congestion on Fifth Avenue.
