One of the longest bridges in existence when it was built, the Seven Mile Bridge has a storied history. If you’ve driven across it (or swam beneath it!) you’ve surely noticed a second, ghost bridge off to the side. This is the original bridge, also known as the Knights Key-Pigeon Key-Moser Channel-Pacet Channel Bridge, and was constructed from 1909-1912 under the direction of Henry Flagler as part of the historic Overseas Railroad. The old bridge, no longer functional, now serves as a popular fishing & sunset watching spot and is home to a wide variety of wildlife– from fish and manatees to birds and butterflies, it’s certainly an important ruin here in Marathon. Its replacement, constructed from 1978 to 1982, is actually a bit shorter than the original: clocking in at 6.79 miles, it has served as the setting for multiple television and movie scenes, as well as the annual “Seven Mile Bridge Run,” in which 1,500 runners traverse its scorching pavement, a thirty-one year tradition!
Famously long and complemented by endless water views on either side, the Seven Mile Bridge is one of South Florida’s most-loved landmarks. If you find yourself zooming across it one evening, you could be in luck: it’s one of the best places to catch the sunset here in Marathon. Time your journey right and you’ll remember the trip for years to come. It’s truly wonderful.
