Bridges are narrow with no shoulders—pull into designated turnouts for photos. The Seven Mile Bridge has a 2-foot clearance, so oversized vehicles beware. Cell reception is spotty between Marathon and Big Pine Key; download offline maps.

1. Plan fuel stops at Marathon (MM 50) and Islamorada (MM 82)
2. Carry cash for small roadside vendors
3. Check bridge openings: no scheduled lifts, but occasional delays for boat traffic

The route is well-paved but subject to tropical downpours (June–November). In rain, reduce speed to 45 mph on bridges due to hydroplaning risk. Use turnouts for emergency stops. For families, the Turtle Hospital (Marathon) offers educational tours, and the Theater of the Sea (Islamorada) lets kids swim with dolphins. Pet-friendly stops include Anne's Beach (Islamorada) with dog-friendly shorelines.

The climate is hot and humid (85-90°F summer, 70-75°F winter); pack water and sunscreen.
