Dead-end streets are roads that do not have an outlet at either end. They are commonly found in residential areas and are used as cul-de-sac or turn-around points. However, there are several other terms that can be used to describe the same type of street. One such term is a no-through road, which also refers to a street that ends without connecting to other streets. A blind alley is another name given to a dead-end street. Finally, a cul-de-sac is a street that allows traffic to enter but not exit from the same direction. Although they all describe the same thing, each synonym has its own unique nuances and connotations.
