State Road 100SR 100 was the designation for the Indianapolis beltway highway that was never completed. The building of I-465 doomed the highway. The last vestige disappeared June 1, 1999, when the part of Shadeland Avenue from US 40 south to I-465 was decommissioned. Most of the south leg and the vast majority of the west leg never existed. |
