IvyTech in Hendricks County was in a storefront in the shopping center where Rural King is now located (Rural King went into the large space that was originally Cub Foods and then became a furniture store; IvyTech was in a unit at the east end of the complex). That location is closed up, signs have been removed, and there's a notice on the door about moving somewhere.
Googling "IvyTech Avon" comes up with an address on Kingston St which is south of US 36 and east of Dan Jones Road.
However, the IvyTech website says that the Avon campus is moving to Plainfield for the Fall 2021 semester. The Plainfield campus is called "Made@Plainfield" and is going into a new building on Reeves Road across from the high school.
