If in Huntington Beach,street is Hamilton with speed limit of 45 miles an hour.Once into Costa Mesa the street becomes Victoria with a speed limit of 40 miles an hour.This street has been reconized as one of the heaviest traveled surface streets in Orange County,Ca.Going uphill the speed limit is 45 mle a hour but watch out,going down hill the speed limit is 40 miles a hour.Tickets written can get confusing indeed,going east or west is it 40 and 15 over or 45 and 10 over.City boundries and sign work are confusing,the City of Costa Mesa which patrols heavily perfers things that way.
