Running across Detroit’s northern edge, 8 Mile has long been more than just a road. Beneath its lanes lies a story of surveys, treaties, and housing maps that turned a simple baseline into one of America’s most infamous dividing lines. At its most extreme, the divide was made concrete — literally — when developers built a six-foot segregation wall in 1941 to separate Black and white neighborhoods.

In this episode, we uncover how 8 Mile became a symbol of division, how Eminem’s rise brought it global attention, and how the community later reclaimed the wall with murals and memory. From Native American trails to Motown, from redlining to rap battles, this is the hidden history of Detroit’s forbidden road.
