Traditionally, Detroiters referred to their freeways by name rather than route number. That is still true today, with most Detroiters still calling the freeways by their names, but numbers are in use as well. Other freeways are referred to only by number as in the case of I-275 and M-59:their names, if any, were never in common everyday usage. M-53, while not officially designated, is commonly called the Van Dyke Expressway.
