The 35 mph speed limit continues from E. Hines Hill across the new Route 8 overpass, through the traffic light at Frontage Road when it becomes W. Hines Hill Road, it suddenly changes to 25 mph (where the old Boston Hills Golf Course used to be). There is no advance warning that the speed limit is going to change. The cops hide on the north side of the road in the back end of the old paved lot where the golf carts used to be. This 25 mph speed limit remains for it entire length of W. Hines Hill until you finally get to Boston Township and it converts back to 35mph.
