A brief history of the Minneapolis skyways JAN 13 2012
If you've ever been to downtown Minneapolis, you've likely used the large network of above-grade covered walkways that now stretches into nearly every corner of the downtown area. I'd always assumed they were built to help downtown workers and residents avoid cold weather during the winter, but that's not the case.
Rather, the skyway system originally emerged from a twofold desire. First, planners in the 1940s and 50s were very concerned about managing increasingly dense pedestrian flows, and viewed skyways as a way to maximize the use of urban space for both people and automobiles (Byers 1998 154). Second, business owners were interested in maximizing their property values, and saw the skyways an opportunity to double the amount of valuable retail space in their downtown buildings (Byers 1998 159).
I used to work in downtown Minneapolis, and the skyways were great in the winter. To be able to take a walk and get lunch without having to bundle up in coat, hat, mittens, scarf, etc. was almost like living in a warm climate...and that's no small thing during a long, dark Mpls winter. (via ★than)
