Two television production firms are planning commercial shoots on Florida Keys bridges today and Thursday and are likely to result in short-term delays for motorists.

Off-duty Monroe County Sheriff's Office deputies will be directing traffic.

Today, producers with a fragrance firm, New York-based Little Bear, Inc., plan to shoot on Channel 5 and Long Key bridges intermittently both days from the late morning to early evening hours. Production durations are between four and eight minutes.

On Thursday, RSA films, a Los Angeles-based firm, has plans to film an automobile on the Seven Mile Bridge for up to four, five-minute intervals each hour between 10 a.m. and 4 p.m.

Weather and other unforeseeable factors could delay or postpone production, according to Rita Troxel of the Florida Keys Key West Film Commission.
