The longest is the Seven Mile Bridge at Marathon, 6.79 miles, which opened in 1982; beside it, a 2.2-mile section of the old bridge is open for walking, running, cycling and fishing and leads to Pigeon Key, the 5-acre island where up to 400 railroad workers lived from 1908 to 1912. The road follows the line of Henry Flagler's Over-Sea Railroad from Miami to Key West, finished in 1912 and closed after the hurricane of 1935. Alongside the highway, the Florida Keys Overseas Heritage Trail has more than 90 miles of paved path for walking and cycling, on a planned 106-mile route, and uses 23 of the old railroad bridges.
Where to go from here.
01Bahia Honda State Park
Monroe County. Sandspur, Loggerhead and Calusa are the three beaches, and the sand here is real sand rather than the thin cover most of the Keys have, because of the way the current works through Bahia Honda Channel.

Monroe County. A nonprofit was formed in 1976 to save this land, and what it saved is a block of tropical hardwood forest that has never been cleared, sitting between the highway and the water in the busiest part of the middle Keys.

Monroe County. Asa Tift, a marine salvage merchant, built it out of local limestone, and Hemingway and his second wife Pauline bought it in 1931. He did a great deal of his work here.
