Rocky River Police Department Patrol the entire area from the Lakewood border to Westlake border. High patrol areas include the area between Rocky River Bridge and the Hilliard onramp/offramp area both Eastbound and Westbound. Other noted areas are the onramp offramp area near Detroit exit in both Directions and Westbound at near the Westlake border. Be prepared for Dark Blue cruisers with little markings and low profile lights. Also they use motorcycles and love to hide in the shadows of the bridges. Typical enforcement is lane 1. Speeders 8+ over the 60MPH limit are most likely to be caught. Remember they often work in multiples and are there year round (I think they get money from the county or state to help cut down speeders)
