Newport, RI → Key West, FL

As you leave the charming coastal town of Newport, Rhode Island, you'll head south on I-95, the backbone of this 1,710-mile journey toward the southernmost point of the continental United States. This legendary interstate carries you through some of America's most historically significant regions, passing through or near major cities like New York, Philadelphia, Baltimore, and Washington, D.C. before eventually merging into I-81 as you move deeper into Appalachia. The first several hundred miles present urban and suburban stretches that require attentive driving, particularly through the Northeast Corridor, but the rewards include glimpses of the Atlantic coastline and the chance to experience the architectural heritage of America's founding cities.

Once you move through the Carolinas and into Georgia and Florida on I-95, the terrain transforms dramatically as you descend toward sea level, leaving behind the rolling hills and forests of the Piedmont. You'll trade mountainous vistas for increasingly flat, humid lowlands characterized by Spanish moss-draped cypress swamps and pine forests that become more tropical as you push southward. Around Jacksonville, you can feel the climate shift noticeably—the landscape opens up, and the subtropical character of Florida becomes undeniable as you continue through Daytona Beach and West Palm Beach before reaching Miami.

The final leg of your adventure requires patience and a different mindset entirely. From Miami, you'll traverse the legendary Overseas Highway (US-1), a breathtaking 161-mile causeway that literally drives across the turquoise waters connecting the Florida Keys. This scenic passage takes you through a chain of islands including Key Largo, Islamorada, and Marathon, where you're never far from the ocean and the driving pace naturally slows to accommodate the unique island character. The entire drive typically takes approximately 28 hours and 40 minutes of actual driving time, though most travelers break it into two or three days to fully experience the dramatic transformation from New England seaside charm to tropical island paradise.

Plan this drive during fall or spring for ideal conditions—summer heat and humidity intensify along the southern portions, while winter snowstorms can complicate early segments through the Northeast. The I-95 corridor can experience significant congestion, especially during holidays and weekends, so timing your departure strategically will enhance the experience considerably
