There is some sort of freestanding object that shows you your speed and has an actual posted speed limit next to it. It shows your speed and if it’s above the number it’ll start flashing. There are usually 1-4 cop cars waiting after the intersection depending on the time of day, but I’ve almost always seen at least one person get pulled over every time I pass the intersection. I highly suggest you slow down as soon as you see it blink. The posted limit is 25mph (could it get any lower..I understand it’s the state limit but that’s excruciatingly slow for that intersection)
