The Long Key Bridge, officially the Dante B. Fascell Bridge, connects Long Key and Conch Key. Stretching nearly two and a half miles, it is the second longest bridge on the Overseas Highway, following the iconic Seven Mile Bridge. This bridge opened in 1982, replacing the original Long Key Viaduct, which was in use by the Overseas Railroad from 1907 to 1935 before being repurposed for highway traffic. As you walk along, you’ll notice the original viaduct adjacent to this bridge, featuring a design of 186 concrete arches. This style has been commonly used in many railroad bridges throughout the Keys.
