Long Key Viaduct fishing bridge

The 1908 Long Key Viaduct, 2.3 miles of historic arches repurposed as a fishing bridge with platforms and parking at both ends, from MM 63.25 to 65.25. More water passes under it than any other bridge in the area, and it rarely gets crowded.

Skill: BeginnerShore, bridge, kayak & wade

How to fish it

Walk out to find your own stretch of rail. Yellow jacks and snapper on the incoming tide along the flat edges; tarpon and snook on the night outgoing. Bring a cart: it is a long walk.

Best tide: Incoming for jacks along the flats; night outgoing for tarpon.

Tide station: Channel Two, west side, Hawk Channel. Current station: Long Key Bridge. See today's tides and currents on the conditions page, or open this spot on the map.
