The Skywalk DSM app -- created ahead of the opening rounds of the 2016 NCAA men’s basketball tournament to avoid confusion on the downtown skywalk system because several loops were closed due to construction -- has been selected for an International Downtown Association Certificate of Merit award within the “Leadership and Management” category, according to a release from the Greater Des Moines Partnership. The app shows the locations of businesses and portions of the skywalk system that are temporarily closed. It is available for Android and Apple mobile operating systems. Polk County, Catch Des Moines, the city of Des Moines, the Iowa Events Center, the Downtown Community Alliance and the Greater Des Moines Partnership collaborated on the innovative on development of the app, which was produced by the Polk County Information Technology Department.
