The city of Thunderbolt is basically a 2-mile stretch of Victory Drive on the east end of Savannah with a speed limit of 35 mph. The local police drive back and forth on US 80 (Victory) looking for speeders, which are not hard to find since the huge hill coming off the Wilmington River bridge tends to cause a sharp increase in the speed of your car. City limits are clearly marked, so be sure you tap your brakes to keep from getting struck by the Thunderbolt!
