History

This limited access highway planned in the 1950s roughly follows the general route of many older at grade highways, including United States Highway 2, United States Highway 27, United States Highway 25, United States Highway 41 among others. Some of these older U.S. Highways, several of which exist yet, in turn replaced the eastern 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 Downtown Connector, is infamous for its bad traffic.

Florida's Turnpike originates near Wildwood and continues southeasterly towards Miami.
