Cops (marked and non-marked) sit in the parking lot or service drive after hours next to BonVenture indoor skating rink. Usually in the dusk or evening hours. They have started sitting here, since the completion of the North Halsted bridge to 12 Mile was completed. The road is only 40, but its only posted once. Be aware, they are sneaky and sit just far enough back from the road, so you can’t see until you pass.
