Nice catch... I just PMed one of the users I've had contact with in RI about this - the other one I can't find their username (it's fallen out of my PM box).
I've kind of adopted RI as it wasn't getting much attention. Only the Freeways & Majors (done on the CT Functional Classification Translation) have been verified & there are some issues at the I-95/I-195 interchange I haven't been able to work out (naming mostly).
I just did the Red Light Cameras in Providence last week too.
