Freeways in metropolitan Detroit

Freeways in metropolitan Detroit consist of several major interconnecting Interstate highways and additional supporting freeways. The Metro Detroit region has an extensive toll-free expressway system which, together with its status as a major port city, provide advantages to its location as a global business center. There are no toll roads in Michigan.

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.
