State Road 100 no longer exists as a state highway; the short final signed section on S. Shadeland Avenue was turned over to the city of Indianapolis in 1999. Originally a beltway around Indianapolis. it was deleted almost completely as Interstate 465 made it irrelevant as any but a local route, having been truncated to a short route between US 40 and I-465 in the early 1990s, when all signed US or state highways going through Indianapolis were diverted onto the I-465 beltway. The highway began just south of U.S. Route 52 at I-465. It traveled northward as Shadeland Avenue. It turned west at Castleton, in northeastern Marion County, following 82nd Street. Between State Road 37A and the distinctive bridge over the West Fork of the White River just east of State Road 431, it became 86th Street. It continued on west along 86th to the far-northwest side of Marion County, where it connected to US 52 at Trader's Point in Boone County.There were two other short sections of Indiana 100. The first section designated as SR 100 ran from US 40 along High School Road south to the Indianapolis Municipal Airport. The second, a short lived section, ran along Troy Avenue from Meridian Street to Bluff Road. This section did not survive long after the decommissioning of SR 37 along Bluff Road.
