A friend of mine totaled her car at that intersection a couple of weeks ago. The officer in the parked sheriff's car was a member of the posse, not a peace officer.
Some observations:
Eastbound traffic is transitioning from a signed 45 to 65 mph zone and then they see a flashing sign advising slow down and busy intersection.
Why in the world does it say "slow Down"? That message means different things to different people. May I suggest 45 mph or even slower. A slower speed limit would have resulted in far fewer accidents and may have saved lives. By the way, I have heard there has been more than one fatality.
Now let's address the parked sheriffs unit with lights flashing. The flashing lights are contributing to the problem. Some people react to the flashing lights by moving over from the outside lane into the right lane where people are attempting to make right turns into the busy intersection. That in and of itself is a recipe for disaster. Furthermore, the flashing lights at night interfere with our ability to identify approaching cars.
Walton County collects a lot of bed tax money that should be used to protect our guests and residents. Let's spend whatever is necessary to improve the traffic management at this intersection.
Lastly, whoever is responsible for managing traffic while the Draeper bridge is being constructed needs to take corrective action NOW!
