The bar The Sandtrap is a real place called JB's Fishcamp. Been in New Smyrna/Bethune Beach since the 1970s.
In a 2021 interview with Dread Central, Mickey Keating spoke about the experience of shooting on location in Florida: "What's funny is in Florida, tourism is surprisingly abundant. And so this little town that I found was actually kind of quickly becoming, you know, huge condos and everything. This town was called New Smyrna Beach and it's about an hour away from Daytona. Fortunately, the main street was built in the 1920s and there were enough things that we could cheat to make it not seem like it was a tourist town... You'd think that it would be empty like in the movie. But the reality is that all the Canadians came down during that time of year when we filmed. So we had to block off that main street, that was all practical. There's no CGI. And right outside the camera, there were dozens and dozens and dozens of Canadian tourists watching as if Marilyn Monroe was running down the street. It was really kind of a trip."
The bridge is called "L.B. Knox bridge" between Flagler Beach and Ormond Beach. And it's in use all year round.
