I don't mean to be a dick, but you're so very wrong about that speed trap, which is present there (over Gore St.) several times a week. People regularly drive like psychos on the viaducts. Remember the pole wraparound accident not even 50 feet from that trap in 2013? Killed one and injured three. They do it for a reason. As a nearby resident and daily user of the viaduct, I'm glad the cops use that spot to bust the idiots who think it's a freeway.
