Abandoned Megaprojects in the United States
Kite & Key Media put together a wonderful compilation of odd abandoned megaprojects within the United States. Some of these unrealized projects include a shatterproof dome over Manhattan to save on snow removal costs, alternate proposals for the Lincoln Memorial, and a new port in Cape Thompson, Alaska to be built with nuclear weapons.
For every unique building you see popping out of an American skyline … there are dozens of crazier projects that were never built.
