Quadrant Routes in Pennsylvania are maintained by the Pennsylvania Department of Transportation. This article lists all the routes and their termini in McKean County. As is the case with the other counties in the state, the route numbers start in the northeast quadrant and go clockwise from the 1000s to the 4000s. Odd numbered roads travel south to north. Even numbered roads travel west to east. There is no specific pattern for numbering order.
The north–south quadrant dividers are PA 59 from the Warren County line to Smethport and US 6 from Smethport to the Potter County line. The east–west divider is not explicitly delineated.
