The area between I-40 and Lebanon Rd. is enforced almost daily during rush hour periods and through the day. Since this is a main travel route to Opry Mills Mall, The airport and several local businesses including: Dell Inc, Gibson Guitars and various industrial type businesses this trap seems to be very effective for the police and quite lucritive as well I might add. The speed limit is 55mph. I would not go 56mph and make sure all your lights work and tags up to date. The same guy also patrols Murfreesboro Rd. and switches positions throughout the day. You’ll see him; a motorcycle cop; white guy with a big moustache.
