UCan'tTouchThis has the helicopter & Jaimie Lee on the OLD SEVEN MILE...........didn't they blow up a scaled model of OLD SEVEN MILE in that movie.

Old Seven Mile is the one that is really narrow. It was used for automobile traffic from the thirties until about forty years ago when New Seven Mile opened in early 1982.
It (Old Seven Mile) was the former railroad that was built around the turn of the century and heavily damaged during that super powerful hurricane in 1935, causing the railroad to go out of business but not before selling the seven mile railway bridge to the goverment..........after 1935 it was made into an automobile bridge with the recycled railroad tracks being re-purposed/recycled as the guardrails to keep cars from going in the water after a tire blow-out, someone falling asleep, or wreck, or whatever.

I'm not sure about this but what friends that live in FLA told me is that they closed all of Old Seven Mile some years back and they had planned to do certain repairs and then had planned to re-open about a 2.5 mile portion sometime in 2021 (but that was the goal about five years back, but I have no clue if they are still on schedule or if it was abandoned or postponed) What I seem to recall that my friends told me was that the approx 2.5 mile portion was all they could do, since years ago they removed portions of the bridge (purposely making huge gaps) , to keep folks from accessing and continuing along its entire length. The re-opening of the 2.5 mile portion is gonna be as a pedestrian bridge, as it was since the eighties until closed for further repair during the teens. You can see OLD SEVEN MILE in the foreground of the photograph above.....................NEW SEVEN MILE is in the background and has a prominent hump at one point in the bridge for boat clearance. You can clearly see one of the missing Removed sections in Old Seven Mile that was done to keep folks from getting any farther on it. It is my understanding that they have no intention of ever re-connecting the cut-out sections or attempting to re-hab or re-use or attempt any repair to the rest of the decaying Old Seven Mile. Someone that is a current resident of South Florida would probably know. My info is outdated, unsubstantiated heresay, so it is likely worthless.
I do know that driving US 1 to the Florida Keys in the early 1970's was an experience while crossing OLD SEVEN MILE. Full size cars and mid-size cars in 1972 were significantly larger than today's largest SUV and DUI Laws at that time were very lax and had very minimal fines and no punishment............you had to have been around then to know what I'm talking about. You also had no real standards in enforcement of trailer hitch engineering as there were too many homemade ones then and then folks towing crap built things with only steel chains affixed to the car's bumper........many things looked like Jethro Bodine had made them when he was drunk.
