For the centennial year of the Iowa Highway Commission/Iowa Department of Transportation, a historical “Photo of the Week” is being posted online. I have added a link in the blogroll.
The first photo is the most obvious choice, and probably THE photo of the first decade of roads in Iowa: A Model T working through axle-deep ruts on a muddy Lincoln Highway in Story County in 1918. Conditions like this were the basis for the Good Roads Movement in Iowa. A piece about the movement written for American Motorist magazine six years before that can be read via Google.
