Interstate 75 (I-75) is a major north–south Interstate Highway in the Great Lakes and Southeastern regions of the United States. As with most Interstates that end in 5, it is a major cross-country, north–south route, traveling from State Road 826 (SR 826, Palmetto Expressway) and SR 924 (Gratigny Parkway) on the HialeahMiami Lakes border (northwest of Miami, Florida) to Sault Ste. Marie, Michigan, at the Canadian border. It is the second-longest north–south Interstate Highway (after I-95) and the seventh-longest Interstate Highway overall.[2]

I-75 passes through six different states. The highway runs the length of the Florida peninsula from the Miami area and up the Gulf Coast through Tampa. Farther north in Georgia, I-75 continues on through Macon and Atlanta before running through Chattanooga and Knoxville and the Cumberland Mountains in Tennessee. I-75 crosses Kentucky, passing through Lexington before crossing the Ohio River into Cincinnati, Ohio. In Ohio, the highway runs up the western side through Dayton and Lima before crossing into Michigan north of Toledo. I-75 runs northeasterly along the Lake Erie shoreline and Detroit River into the city of Detroit before turning northwesterly and northward to the Mackinac Bridge where the freeway crosses the strait between Lakes Huron and Michigan. Farther north, I-75 approaches the Canadian border at Sault Ste. Marie, downriver from Lake Superior, 1,786.5 miles (2,875.1 km) from its origins near the subtropical Atlantic Ocean.
