99% Invisible-94- Unbuilt

There is an allure in unbuilt structures: the utopian, futuristic transports, the impossibly tall skyscrapers, even the horrible highways, all capture our imagination with what could have been. Whether these never built structures are perceived as good or bad, they still had an effect on the environment that does exist. We talk with Allison Arieff, John King and Andrew Lynch about the amazing things we missed out on and the bullets we dodged in the history of the unbuilt in San Francisco and New York City.
