On 10/31 I received an email from a Tesla Advisor regarding a broken stall that has since been fixed. During the conversation she said “Also, we have several new Superchargers planned for the area, including a V3 site in Michigan City, IN which we are breaking ground on soon and will help traffic from Chicago to Michigan.”
I’m not from the area so I can’t tell you anymore, hope someone from the area can confirm a more precise location soon!
