Center Line: the whole city sits inside Warren
Center Line is a small city completely surrounded by Warren — the result of incorporating first, in 1925, before Warren Township grew up into a city around it.
Draw Center Line on a map and you’ve drawn a small square island. Every road that leaves it crosses into Warren. That’s because Warren wraps the whole city on every side — all roughly 1.7 square miles of it. Center Line has its own city government, its own schools, its own police. And it’s entirely landlocked by another town.
The name came long before any of that. The story goes that three old Native American trails ran north out of Detroit toward the trading posts. The area sat on the middle one, and that trail was the “center line.” In the mid-1800s the crossroads was known as Kunrod’s Corner. A German Catholic community grew up around St. Clement Church, built in 1854. That way settlers wouldn’t have to walk all the way to a Detroit parish for Sunday Mass.
The reason Center Line ended up an island is a quirk of timing. It incorporated as a village in 1925, with voters approving the charter that November. Then it stepped up to a full city in 1936. The farmland all around it was Warren Township, and the township kept growing. It incorporated as the city of Warren in the 1950s. Warren then expanded outward until it had completely encircled the older, smaller community that had jumped first.
So Center Line never moved. Everything around it did. It’s a tidy lesson in how Michigan’s patchwork of cities and townships actually formed. Whoever incorporated earliest got to keep their lines, and the latecomers had to build around them. Drive Van Dyke straight through and you cross from Warren into Center Line and back into Warren in a few minutes. You usually won’t notice the borders at all.
