Michigan - U.S. Highway 24 and Interstate 75
At the Michigan-Ohio border north of Toledo.
When I-75 first opened in Michigan and connected with I-280 through Toledo, Alternate US 24, which ran on today’s M-125/I-75 Connector and then onto Summit Street in Toledo (US 24 proper ran, and still runs along Telegraph Rd) was temporarily switched to the freeway, before it disappeared altogether.
