How to Get to the Seven Mile Bridge

Where is the Seven Mile Bridge?

The Seven Mile Bridge is located in the heart of the Florida Keys, connecting Knights Key in the Middle Keys to Little Duck Key in the Lower Keys. It is part of the Overseas Highway (US-1), a legendary road trip route stretching 113 miles from Key Largo to Key West. The bridge lies approximately 50 miles northeast of Key West and about 115 miles southwest of Miami.

The bridge is fully integrated into US-1 — you don’t need a special turnoff to find it, but knowing the best approach points, stops, and parking areas will make your visit smoother and more enjoyable.

Driving from Miami

1. From central Miami, take US-1 South (also known as the Dixie Highway) towards Homestead.
2. Pass through Florida City — this is your last major stop for large supermarkets and chain stores before entering the Keys.
3. Continue south into Key Largo, the first island in the Florida Keys.
4. Follow US-1 through Islamorada, Layton, and Marathon.
5. The Seven Mile Bridge begins just after Marathon’s southern end at Knights Key.

Driving time: 3.5–4 hours, depending on traffic and stops.

Scenic tip: Aim to drive during daylight for the best water views — early morning or late afternoon offers the most dramatic light.

Driving from Key West

1. From downtown Key West, head east on US-1 North.
2. Pass through Stock Island, Boca Chica Key, and Big Coppitt Key.
3. Continue through Sugarloaf Key, Cudjoe Key, Summerland Key, and Bahia Honda Key.
4. Cross the famous Bahia Honda Bridge and you’ll soon approach Little Duck Key — the southern end of the Seven Mile Bridge.

Driving time: Approximately 1 hour, depending on traffic and stops.

Tip: The northbound view offers a unique perspective of the bridge — if you can, try to drive in both directions during your visit.

Flying into the Florida Keys

While most visitors fly into Miami International Airport (MIA) or Fort Lauderdale-Hollywood International Airport (FLL) and drive, there is also the option of flying into Key West International Airport (EYW), just an hour from the bridge.

• MIA to Seven Mile Bridge: ~115 miles, 3.5–4 hours by car
• FLL to Seven Mile Bridge: ~140 miles, 4–4.5 hours by car
• EYW to Seven Mile Bridge: ~50 miles, about 1 hour by car

Rental cars are available at all airports, and shuttle services run between Miami and Key West daily.

Public Transportation Options

Although most visitors choose to drive, there are other ways to reach the Seven Mile Bridge:

• Keys Shuttle: Daily service between Miami, Fort Lauderdale, and the Keys. Drops off in Marathon and Key West — you can then arrange local transit or taxi to the bridge area.
• Greyhound / FlixBus: Intercity buses operate along US-1, with stops in Marathon and Key West.
• Ride-hailing apps: Uber and Lyft are available in parts of the Keys, though availability can be limited in more remote areas.

Keep in mind that the bridge itself has no pedestrian sidewalk for its entire length — public transit will get you nearby, but not onto the active bridge span.

Parking Near the Seven Mile Bridge

There is no parking allowed on the active bridge. Instead, look for these nearby options:

• Knights Key side: Public parking areas near Marathon’s south end and the entrance to the old bridge pedestrian path (where open).
• Little Duck Key side: Day-use parking near the bridge approach and small beach areas.
• Pigeon Key Visitor Center: Offers parking for visitors taking the tour and walking/cycling the restored old bridge segment.

Always observe posted signs and restrictions. Parking is free in many areas, but some parks and day-use areas may charge a small fee.

Scenic Stops Along the Way

• Key Largo: John Pennekamp Coral Reef State Park
• Islamorada: Robbie’s Marina — famous for feeding tarpon
• Marathon: Turtle Hospital and Sombrero Beach
• Bahia Honda State Park: Stunning beaches and bridge views

Building these into your journey not only breaks up the drive but also enriches your Keys experience.

Travel Tips for a Smooth Trip

• Fill up your gas tank before leaving the mainland or Key West — stations are plentiful but can be pricier in remote areas.
• Bring water and snacks, especially if you plan multiple scenic stops.
• Drive cautiously — speed limits are enforced, and wildlife can sometimes be on the road.
• Plan for possible slow traffic during weekends, holidays, and special events.
