Police about once a month sit on the East side of the interchange on the east bound on ramp. Usual configuration is one unmarked police car sits at a 90 degree angle to the road up on the side of the hill behind the last tree running the radar. Usually between 8-18 police cars are lined up behind the trees up the on ramp back towards Ridge. Most people are usually clocked under the ridge road ramps in a 60mph zone. The 85th percentile traffic runs 75-80. Recommend to slow down toward the first bridge and watch the trees up to the right on the south side of the ridge road on-ramp. Otherwise, keep running!
