History

This limited access highway planned in the 1950s roughly follows the general route of the older at grade United States Highway 27, which in turn replaced the western route of the old Dixie Highway.

I-75 connects Canada with the southern tip of Florida. The Alligator Alley section west of Ft. Lauderdale is due east/west.
I-175 and I-375 are very brief Interstates that go east into downtown St. Petersburg, while I-275 goes into the heart of Tampa, across the Howard Frankland Bridge into St. Petersburg, then south across the Sunshine Skyway Bridge, reconnecting with I-75 in Manatee County, Florida.
In the center of Atlanta, I-75 merges with I-85 for a short time. This strip of highway, called The Connector, is infamous for its bad traffic.
