Oklahoma City, OK → Key West, FL

The journey from Oklahoma City to Key West stretches across roughly 1,564 miles of remarkably diverse American terrain, primarily following Interstate 44 east through Missouri before transitioning to I-75 southbound through Tennessee, Georgia, and into Florida. Once you cross into the Sunshine State, the route becomes more scenic as you navigate through central Florida on I-75 before eventually connecting to the Turnpike system and the scenic Overseas Highway (US Route 1), which carries you across the famous bridges and keys leading to the southernmost point of the continental United States. This approximately 26-hour drive offers you a fascinating cross-section of the American South, from the plains and rolling hills of the interior to the subtropical landscape of southern Florida.

Your first major leg takes you through the Ozark region of Missouri and Arkansas, where you'll encounter gentle elevation changes and transition from Oklahoma's flat terrain into more forested, rolling countryside. As you push deeper into the South along I-75, you'll pass through or near several notable cities including Memphis, Tennessee; Atlanta, Georgia; and Jacksonville, Florida—each providing opportunities to stretch your legs or grab a meal during your journey. The landscape gradually transforms as you travel southward, with dense pine forests eventually giving way to the palmettos and cypress swamps characteristic of central and southern Florida.

The final leg of your trip is particularly distinctive as you leave the mainland behind on the Overseas Highway, a scenic route that literally drives you across a series of islands connected by causeway bridges, offering stunning ocean views and glimpses of the Keys' unique ecosystem. This section includes the famous Seven Mile Bridge, which connects the Middle Keys to the Lower Keys and provides one of the most memorable driving experiences in Florida. Urban driving segments are minimal on this route, with most of your time spent on interstate highways through less congested areas, though you should anticipate moderate traffic around major metropolitan areas like Atlanta and through central Florida.

For the most comfortable driving experience, plan this trip for late fall through early spring, when temperatures are moderate and humidity is lower throughout the South and Keys. Summer and early fall bring heat, humidity, and the potential for afternoon thunderstorms, while winter remains pleasant in Florida but can occasionally bring rain to northern sections of the route.
