A RARE Crocodile Crossing Sign!
Crocodile Crossing MM 112.8
There are two ‘Crocodile Crossing’ signs on your way down the Keys. Just taking a photo with or without a family member being in it makes for a good picture to tell your out-of-town friends who’ve NEVER seen or heard of a ‘Crocodile Crossing’ sign. In fact, I’ve been told by a reliable blog reader James W. that it may very well be the only “Crocodile Crossing” signs in the western hemisphere . . . at least in English he adds. 
Being 100% honest… YES, you can see an occasional crocodile heading south on US-1 but nowhere near the amount of alligators you’ll be GUARANTEED of seeing on I-75’s Alligator Alley through the Everglades. And yes, there’s a difference between Florida Key’s Crocodiles -vs- Everglades’ Alligators!
The first sign at MM 112.8 is highly unlikely of a sighting since road construction crews have erected fences on both sides of the road that now sadly appear to be permanent. I’m sure the sign there will eventually come down since it’s no longer possible for a gator to cross. So take a few minutes and get off at the access road at MM 108.2 (southbound before the bridge) where you’ll have your best chance on seeing a crocodile. Notice BOTH the standard yellow diamond road sign and the more unusual lettering on the bridge itself! (seen below)
Oh yeah, DON’T feed the gators, they are wild! In the Everglades, experienced & trained Air Boat tour guides show tourist how much the gators LOVE human food in order to get them closer to the boat for a photo-op; believe it or not it’s those large puffy marshmallows! (fact) I can’t stress enough and repeat, DO NOT FEED THE WILD GATORS… or your friends may be calling you lefty after you do! That would give a whole new meaning to the term HAND OUT!
