High Quality Content by WIKIPEDIA articles! Interstate 65 (I-65) is a major Interstate Highway in the United States. The southern terminus is located at an intersection with Interstate 10 in Mobile, Alabama, and its northern terminus is at a traffic light with U.S. Route 12 and U.S. Route 20 (Dunes Highway) in Gary, Indiana, southeast of Chicago, Illinois. I-65 is humorously known as Auto Alley because of the large number of automotive OEM and supplier firms that have facilities within an hour's drive of the highway (questionable). Of these, the most notable are the Subaru plant in Lafayette, Indiana, the Hyundai plant in Montgomery County, Alabama, the General Motors Corvette plant in Bowling Green, Kentucky, the Mercedes Benz plant in Tuscaloosa County, Alabama, and the currently-dormant GM plant (formerly Saturn) in Spring Hill, Tennessee.
