1940 Map of East Dubuque

About this map

The Mississippi River creates a dynamic western boundary for Jo Daviess County in this 1940 edition, featuring a complex network of islands and waterways like Ninemile Island and the Menominee Slough. The industrial and transit character of East Dubuque is clearly defined by the heavy rail presence of the Chicago Burlington and Quincy and the Illinois Central railroads, which hug the riverbank before heading inland. To the east, the rural landscape of Menominee township is dotted with traditional country schools, including Miller Sch, White Sch, and Ridge Sch, serving the upland farming communities. The map captures a specific era of infrastructure, showing the critical junction where rail lines met the river trade, while also marking the Illinois-Wisconsin Boundary Line at the northern edge of the quadrangle.
