The Long Key Bridge, officially known as the Dante B. Fascell Bridge, is a bridge in the Florida Keys connecting Long Key and Conch Key, roughly halfway between Miami and Key West. At a length of nearly two and a half miles, it is the second longest bridge on the Overseas Highway after the Seven Mile Bridge. The current bridge opened in 1982, replacing the parallel Long Key Viaduct, which carried the Overseas Railroad from 1907 to 1935 and was repurposed for highway use shortly after.
