As part of their course “Integrative Field Experience” prepared for the Detroit Eastside Community Collaborative, Kami Brown and Michael Ritz from the University of Michigan College of Architecture & Urban Planning created this map of street congestion on the east side in 1996.
Red = Congested two-way streets
Blue = Proposed one-way streets
It appears that St. Paul, Belveidere, and Dequindre were the most congested two-way streets at the time of the project.
I discovered this map, currently serving as a window shade, in the basement of St. Charles Catholic Church on Baldwin Street.
