Old Seven Mile Bridge — restored span return
Florida · Rail-trail
Walk from the public Old Seven parking area to the restored north span. Follow only the 2.2-mile public bridge toward Pigeon Key and retrace before the island admission area. Do not ride the traffic-carrying new Seven Mile Bridge, closed historic spans or the full Overseas Highway route. Yield generously to the tourist tram.
