Spanning the turquoise waters between Bahia Honda Key and Spanish Harbor Key, the Old Bahia Honda Bridge stands as a striking relic of Florida’s early 20th-century engineering ambitions. Once a vital link along Henry Flagler’s Overseas Railway, the bridge now serves as both a historical landmark and a unique vantage point for visitors exploring the lower Florida Keys.
Today, the bridge’s remaining section is a centerpiece of Bahia Honda State Park, drawing sightseers, photographers, and anyone curious about the region’s transformation from remote islands to accessible destinations. Its weathered steel and concrete arches offer a tangible connection to the Keys’ storied past.
History and Significance
The Old Bahia Honda Bridge was completed in 1912 as part of the Florida East Coast Railway’s ambitious extension to Key West. Its unique truss design was necessary to span the deep, swift channel at Bahia Honda, which posed one of the greatest engineering challenges of the entire Overseas Railway project. After the Labor Day Hurricane of 1935 devastated much of the railway, the bridge was repurposed for automobile traffic as part of the Overseas Highway, further cementing its role in connecting the Monroe County islands.
Today, the bridge’s central section is closed to vehicles and much of the structure is inaccessible, but a short segment remains open to pedestrians, offering panoramic views and a sense of the bridge’s original scale and purpose. The bridge’s silhouette, especially at sunset, is an iconic image of the lower Keys.
What to See and Do
The accessible portion of the Old Bahia Honda Bridge is reached via a short, sloping path from the north side of Bahia Honda State Park. From the bridge, visitors enjoy expansive views of the Atlantic Ocean, the Gulf of Mexico, and the park’s beaches. It’s a favorite spot for birdwatching, especially for pelicans and ospreys, and for spotting marine life in the clear waters below.
Photography is a major draw—sunrise and sunset offer particularly dramatic lighting, with the bridge’s rusted steel framing the changing sky. Interpretive signs along the path provide historical context and details about the bridge’s construction and the broader history of the Florida Keys. Swimming, snorkeling, and kayaking are popular in the surrounding park, and the bridge serves as a scenic backdrop for these activities.
Planning Your Visit
The Old Bahia Honda Bridge is located within Bahia Honda State Park, about 37 miles northeast of Key West along U.S. 1. The park is open daily, but entry fees apply. Parking is available near the bridge access trail, and restrooms, picnic areas, and concessions are located nearby.
Summer weekends and holidays can be crowded, especially during midday. For a quieter experience, consider visiting early in the morning or late in the afternoon. The bridge’s walking section is not shaded, so bring sun protection and water. Note that climbing on or accessing closed sections of the bridge is strictly prohibited for safety reasons.
Nearby Destinations
The Old Bahia Honda Bridge is a natural stop for anyone traveling through the lower Keys. Nearby, the Old Seven Mile Bridge offers another perspective on the region’s transportation history and is popular with walkers and cyclists. Nature enthusiasts may also want to explore the Blue Hole Trail on Big Pine Key, a short drive away, for a chance to spot Key deer and freshwater wildlife.

Old Bahia Honda Bridge in the Keys
As part of Monroe County, the Old Bahia Honda Bridge is a physical and symbolic link in the chain of islands that make up the Florida Keys. Its presence marks a turning point in the region’s accessibility and development, and it remains a must-see for those interested in the Keys’ transformation from isolated outposts to one of Florida’s most distinctive destinations.
While the bridge no longer carries trains or cars, it continues to connect visitors with the natural beauty and layered history of the area. The surrounding waters and beaches are among the clearest and most inviting in the Keys, making this a worthwhile stop whether you’re on a day trip from Key West or exploring the entire island chain.
JJ’s Tip
For the best views and fewer crowds, visit the bridge early in the morning. Bring polarized sunglasses to cut glare and spot rays or sea turtles below. If you’re a photographer, plan for golden hour lighting—sunset from the bridge is memorable, but sunrise offers a quieter, equally stunning experience.
Whether you’re interested in history, scenery, or simply stretching your legs on a long drive through the Keys, the Old Bahia Honda Bridge offers a unique perspective on Monroe County and the enduring allure of the Florida Keys. Take your time, soak in the views, and appreciate this enduring piece of Florida’s coastal story.
