The concept behind The Idle was conceived in 2013,[2] through the vision of Tom Battista, a local Indianapolis property developer and entrepreneur.[6] It was partially funded through Patronicity, a crowdfunding website which raised $48,462.[5] Through a match, the Indiana Housing and Community Development Authority had contributed an additional $41,000.[2] Since the park is located on federal highway land, its creation required cooperation between the Federal Highway Administration, the Indiana Department of Transportation, and the Indianapolis Department of Public Works.[5]
The park features an accessible limestone trail leading to a viewing platform, which is furnished with seats salvaged from the city's former Bush Stadium.[4] It also features native vegetation, repurposed ash tree benches, as well as informative signage explaining the area's history and concept behind the project.[5]
