Route 47-A • The Harrison Loop
Length: 14.2 miles | Stops: 23 | Hazards: I-75 merge, railroad crossing at 8:42 AM
Begins at the Warren Central depot, cuts north through Harrison Township, skirts the abandoned General Motors plant where rust blooms like iron flowers. The children on this route know the rhythm: brake squeal at the hill, the dip before the bridge, the way the light hits the water tower at exactly 7:18 AM.
Route 47-B • The Van Dyke Express
Length: 18.7 miles | Stops: 31 | Hazards: Construction zone (seasonal), pedestrian bridge blind spot
The route that taught me the map lies. Runs parallel to Van Dyke Avenue, crosses the railroad tracks three times. On fog mornings, the headlights of the oncoming trains look like stars falling backward. I count them.
Route 52-C • The Clinton River Run
Length: 22.1 miles | Stops: 28 | Hazards: Ice bridge variance, deer corridor at mile marker 7
Follows the Clinton River southward. In January, the river freezes in patches—blue-black glass under the roadbed. I watch the expansion joints. They sing before they crack. This route carries the children of Mount Clemens, Port Huron's cousins, whose ancestors walked the same ice.

The Unmapped Paths
Some roads appear only when needed. The gravel shortcut past the old quarry when Route 24 floods. The service road behind the library when the main gate jams. These are not on any official sheet. They exist in muscle memory, in the callus on my thumb where it rests on the gear shift.
