The Interstate 8 Athletic Conference is an athletic conference for high schools in Michigan formed in 2014 with eight schools in south central Michigan. The conference currently consists of seven Class A and B schools from Barry, Branch, Calhoun, and Jackson counties. The name of the conference derives from the I-69 and I-94 corridors.
History
The conference was founded in 2014 with the following charter members: Charlotte, Coldwater, Harper Creek, Jackson Lumen Christi, Jackson Northwest, Marshall, Parma Western, and Pennfield.
After the 2015-16 school year, Charlotte left the conference and eventually rejoin the Capital Area Activities Conference. Hastings from the Ottawa-Kent Conference was selected to replace Charlotte starting in the 2016-17 school year.[1]
In August 2022, it was announced that Lumen Christi, the smallest member and the only private school in the conference would depart the Interstate 8 to join the Catholic High School League beginning in the 2023-24 school year.[2] With Lumen Christi's departure, the remaining seven schools at some point or another participated in the old Twin Valley Conference that existed from 1931 to 2001.
