I'm not sure what you mean by "ends" but there are parts of the Pacific Coast Highway (between Malibu and Santa Barbara) with 55 mph speed limits and stoplights.
What I mean is it's a 50-60 mile stretch of highway that unceremoniously stops at a traffic light with no highway on the other side. It's a very weird thing.
Or Route 1 at least through Central New Jersey, 55 and stoplights all over.
Same in all of New York anywhere north of the city. It's very common.
