Imagine cruising across the open ocean in your car, surrounded by endless turquoise waters and island views straight out of a postcard. No ferry, no boat — just your car and the road ahead. Welcome to the Overseas Highway, a 180-kilometer (113-mile) engineering marvel that lets you drive from mainland Florida to Key West, passing over 44 tropical islands along the way.

One of America’s most scenic drives

Known as one of the most iconic and picturesque road trips in the United States, the Overseas Highway connects the Florida Keys through a series of 42 bridges, floating above the Atlantic Ocean, Florida Bay, and the Gulf of Mexico. It’s more than just a route — it’s an experience.

Travelers often describe the drive as “floating over the sea,” with panoramic views of clear blue waters stretching as far as the eye can see. The route starts in Knight’s Key in the Middle Keys and ends in Little Duck Key in the Lower Keys, culminating in a visit to Key West, the southernmost point in the continental U.S.

The crown jewel: the Seven Mile Bridge

Perhaps the most famous section of the Overseas Highway is the Seven Mile Bridge, located in the second half of the drive. When it was originally built between 1909 and 1912, it ranked among the longest bridges in the world. Even today, it’s the longest bridge in Florida and remains one of the longest in the United States.

The Seven Mile Bridge offers one of the most breathtaking stretches of road in the country — and yes, it’s Instagram-worthy. For those who want to take their time, the original version of the bridge is now open to pedestrians and cyclists, allowing you to walk or bike over the ocean and enjoy the views at your own pace.

Highlights along the way

Besides the thrilling drive, the Overseas Highway offers multiple highlights that make the journey unforgettable:

  • Key Largo: The first major island you encounter, known for its diving spots and coral reefs.
  • Marathon: A great place to stop for fishing, kayaking, or exploring nature parks.
  • Bahia Honda State Park: One of Florida’s best beaches, ideal for swimming and snorkeling.
  • Mallory Square in Key West: Famous for its sunset celebrations — a perfect way to end the trip.

Many roadside spots allow you to safely pull over and take in the ocean vistas. Whether you’re behind the wheel or stopping for photos, the drive offers countless opportunities to connect with Florida’s tropical beauty.

A journey like no other

The Overseas Highway is not just a road — it’s a seamless blend of adventure, nature, and history. From engineering feats like the Seven Mile Bridge to the laid-back island vibes of Key West, this highway transforms a road trip into a lifetime memory.

So next time you think crossing an ocean means boarding a boat, think again. In Florida, all you need is a car and a sense of adventure.
