Heading north on Meridian at the I-10 overpass the speed limit is 35 mph and stays that way for about a quarter mile down a long hill and then becomes 45 mph. It is hard not to drive over 35 mph going down the hill just coasting, and there are no speed limit signs until the 45 mph one appears. The trap is at the bottom of the hill either on the left where a tree-obscured street enters Meridian or (usually) on the right at an abandoned convenience store’s entrance.
