The Long Key Bridge, officially known as the Dante B. Fascell Bridge, is a prominent landmark in the Florida Keys, connecting Long Key and Conch Key. This impressive structure is an integral part of the iconic Overseas Highway (US 1), serving as the second-longest bridge along this scenic route. Stretching approximately 2.3 miles across the Long Key Channel, it offers a vital link for travelers journeying between Miami and Key West, situated roughly halfway between these two vibrant Florida destinations.

Visitors are consistently drawn to the area for its unique blend of modern engineering and rich history. The bridge provides expansive views of the emerald waters surrounding the Keys, a truly captivating sight. What makes this location particularly special is the parallel presence of the historic Long Key Viaduct, an engineering marvel from 1907 that once carried Henry Flagler's Overseas Railroad. This juxtaposition allows for a fascinating glimpse into the evolution of transportation in the region, making it a popular spot for those seeking both natural beauty and historical context.

While the modern Long Key Bridge primarily facilitates vehicle traffic on the Overseas Highway, the adjacent Long Key Viaduct offers a different experience. Now repurposed as a pedestrian-only bridge and fishing pier, it provides an accessible pathway for walking, biking, and fishing. This section is part of the Florida Keys Overseas Heritage Trail, making it an excellent option for those looking to explore on foot or by bicycle. Parking is available near the access points to the old viaduct, allowing easy entry for those wishing to enjoy a leisurely stroll or cast a line.

The Florida Keys generally offer pleasant conditions for visiting year-round, though the cooler, drier months from November to May are often considered ideal for outdoor activities. This period avoids the peak heat and humidity of summer, as well as the hurricane season. Activities at the Long Key Bridge include scenic drives across the modern structure, as well as walking, cycling, and fishing on the historic Long Key Viaduct. The area is known for attracting various marine life, including large sharks, making it a popular destination for anglers.

Exploring the Long Key Viaduct offers a chance to walk along a piece of history, with its distinctive 186 concrete arches providing a picturesque backdrop. Many visitors enjoy the opportunity to spot marine life in the clear waters below or simply take in the vast ocean vistas. The ability to observe both the contemporary bridge and its historic predecessor side-by-side creates a memorable experience, highlighting the ingenuity and perseverance behind connecting the remote islands of the Florida Keys.

Whether you're interested in a leisurely walk, a scenic bike ride, or a spot of fishing, the Long Key Bridge area provides diverse opportunities for outdoor enthusiasts. You can discover various routes and plan your visit to this unique Florida Keys landmark. With komoot, you can easily find trails that suit your preferred activity, from gentle strolls along the old viaduct to longer cycling adventures on the Florida Keys Overseas Heritage Trail.
