I-75, Atlanta, Georgia
Interstate 75 (I-75) is a major north–south Interstate Highway in the Great Lakes and Southeastern regions of the United States. It travels from State Road 826 (Palmetto Expressway) and State Road 924 (Gratigny Parkway) in Hialeah, Florida (northwest of Miami) to Sault Ste. Marie, Michigan, at the Ontario border. Interstate 75 is the seventh longest interstate highway after Interstate 95 and passes through six different states: Florida, Georgia, Tennessee, Kentucky, Ohio and Michigan.
Due to traffic levels on the Interstate, much of the route is six lanes even in rural areas. The longest continuous segment of six-lane (or more) roadway in the U.S. is along I-75 from the Florida's Turnpike junction in Wildwood, Florida to I-24 in the Chattanooga area, using I-475 to bypass Macon, Georgia, though this long stretch has an exception to its 3 lanes or more continuity around the I-75/I-475 split where it is 2 lanes on each side for only a few miles.
