Shinola, a Detroit-based company, is set to expand its hotel portfolio by opening a second hotel in Indianapolis. The investment group Boxcar Development, led by Herb Simon and the Simon family, has submitted a preliminary proposal to transform the former CSX building site in downtown Indianapolis. The ambitious redevelopment plan includes the Shinola Hotel, a 4,000-seat music venue managed by Live Nation, retail spaces, and a pedestrian skybridge connecting Pennsylvania Street to Gainbridge Fieldhouse, the home of the Indiana Pacers.
