Oobject just released a list that's as interesting as it is depressing called "15 skyscrapers on hold." There's a few on there you've probably already heard about, such as the Chicago Spire, which may never be restarted again. Its aborted construction has left a hole 76 feet deep and 110 feet wide in the middle of Chicago, and that's not the only building there to be paused.
Also on the chopping block is 58 Leonard Street, a zany skyscraper in New York City that we gave you an early look at. Dubai, the city of seemingly endless construction, also took a hit with a few of its wild and outlandish 'scrapers grinding to a halt. Check out Oobject's list to see what other towers are getting the ax.
