April 9, 2025, Seven Mile Bridge

This iconic bridge is the longest in the Florida Keys, built in 1982 to provide safe stops for visitors to view wildlife and enjoy the stunning green water. The original bridge, constructed in 1912 as a railroad bridge and called the “Eighth Wonder of the World,” was narrow and required focus to cross from Marathon Key to Key West. Today, the old bridge mainly serves as a resting place for pelicans and great blue herons. There are some great benches here, and the Sunset Grill is just off the trail, offering delicious food and drinks. It's an ideal spot for a break to enjoy some incredible scenery.

April 5, 2025, Long Key Bridge

The Long Key Bridge, officially the Dante B. Fascell Bridge, connects Long Key and Conch Key. Stretching nearly two and a half miles, it is the second longest bridge on the Overseas Highway, following the iconic Seven Mile Bridge. This bridge opened in 1982, replacing the original Long Key Viaduct, which was in use by the Overseas Railroad from 1907 to 1935 before being repurposed for highway traffic. As you walk along, you’ll notice the original viaduct adjacent to this bridge, featuring a design of 186 concrete arches. This style has been commonly used in many railroad bridges throughout the Keys.

In the early 20th century Marathon was the center of shipping operations in the region. Ships from Havana and other Caribbean locations would dock near the railway to offload their goods to trains heading north. However, this would all come to end in 1935 when a large storm damaged the rail lines and the highway soon replaced the railroad.

Along the way you'll pass by many State Parks, beaches, bars, restaurants, and marinas; and all of them will be beckoning you to stop and stay a while. On the right day this is one of the best places to ride in the world.

The old 7 Mile Bridge has been paved and is now a good walking and cycling path.

Impressive journey over the »New Seven Mile Bridge«. The old bridge is broken (03/2020), but is partially being renovated. Therefore, the bicycle traffic runs on the hard shoulder of US Highway No. 1. Good nerves are required, partly crumbs and tire parts lie on the bike path.

Occasionally on the way to Key West next to the bridges, which are now cycle paths, you will find legacies of the former railway line.
