The Springdale overpass of Garden Grove Blvd. The speed limit is posted 35 which is very hard to maintain going down the hill in either direction. There is a motor officer very often on both sides of the hill. One side he sits on the sidewalk up near the school and the other in the coin operated car wash near the bushes. By the time you see him, your nailed. People often do 45-50mph which seems reasonable but the posted is 35 so be warned.
