This undated postcard from Zenith Interstate News Company has a very 1960s look to it. The image shows businesses and traffic on the 400 block of West Superior Street in Downtown Duluth, looking northeast.
The caption on the back reads:
Superior Street
Duluth, MinnesotaThis, the main business section of Duluth, is also the main arterial highway to Canada via the scenic North Shore Route.
Of course, the extension of Interstate 35 through the area in the decades that followed meant Superior Street would no longer be “the main arterial highway to Canada.”
