Anyone know anything about them? They seem to have just gone up, roadworks around the area but no set speed limit signs anywhere

I *think* they may be specs cameras, there are about 4 sets of them on each side of the carrage way with two cameras on each pole (over hangs both lanes) The camera's are yellow with two box's either side of the main unit.

Don't these clock your average speed over a certain distance? They seem to be roughly 2 or 3 miles in length to pass all four sets of cameras.

Anyone know anything about them ?

I use the road a fair bit and tbh doesn't seem like an area for concern accident wise.
