The Minneapolis architecture firm City Desk Studio just put a skyway up for sale on craigslist. A freakin' skyway.

It's a steel girder and glass box, 20 x 83 feet, and 14 tall, designed by architect Ed Baker ["the father of the skyways"] to connect JC Penney's and Powers department stores. The 12-inch concrete floor accounts for about half of the skyway's 280,000-lb weight. [That's half a Richard Serra retrospective, for those keeping score at home.] It was apparently assembled in three sections and filled in with glass after it was installed.

City Desk Studio's asking price is currently $79,500, which is a huge discount from the $1.2 million they expected to bring in by turning the skyway into the Skyway Retreat lakefront cabin and selling 12 4-week shares for $100,000 apiece.
