Interstate 75 (I-75) runs from Cincinnati to Toledo by way of Dayton in the US state of Ohio. The highway enters the state running concurrently with I-71 from Kentucky on the Brent Spence Bridge over the Ohio River and into the Bluegrass region. I-75 continues along the Mill Creek Expressway northward to the Butler County line just north of I-275. From there, the freeway runs into the Miami Valley and then passes through the Great Black Swamp before crossing into Michigan.
