Walk, jog, cycle or drive across one of the longest bridges in North America to take in the scenic ocean views it provides.
Once among the longest bridges in the world, the Old Seven Mile Bridge connects Marathon with the southern Keys. Travel along the Overseas Highway to cross this feat of modern engineering and experience the sweeping vistas and incredible photo opportunities. Follow it out and keep going to Pigeon Key, where you can admire the snaking bridge from afar.
Walk along the pedestrian section of the bridge and learn about the history of the railroad that was once so integral to the Keys.
The quickest way to see the bridge is by driving across it from Marathon to reach Little Duck Key and the scenic Veterans Memorial Park. The Seven Mile Bridge was built very low to the sea beneath it, so at times it is as if you are driving on water. As you sit on the sandy beaches of the park, you can gaze back across the bridge. Visit at sunset to admire the huge concrete portions of the bridge glowing in the amber light. Look for the small arc in the center of the bridge where it peaks at a height of 65 feet (19.8 meters), allowing taller boats to pass beneath.
Another way to explore the bridge is by renting a bicycle from the northern end of the bridge. Cycle the 2.2-mile (3.5-kilometer) section of the Old Seven Mile Bridge that leads to Pigeon Key. The leisurely ride reveals a lot of historical information and you can also see the original tracks used on the Overseas Railroad. Enjoy a picnic on Pigeon Key before heading back to Marathon.
A final option is jogging. Each April the bridge closes for an afternoon so thousands of joggers can come together to take over the bridge. The Seven Mile Bridge Run is a family-friendly event that has been taking place since 1982 as a celebration of the bridge.
The Seven Mile Bridge begins in Marathon and runs for just shy of 7 miles (11.3 kilometers) until it reaches Little Duck Key. The road is public, and there is no toll charge.
