 A signalized intersection with SR 51 in Lake Township just south of Northwood marks the starting point of SR 579.The route starts out in a northeasterly direction, but as it sweeps by the southeast corner of the former Woodville Mall, it turns due east, as it lines itself up with the boundary between Lake Township and the City of Northwood.SR 579, which starts out briefly as a five-lane road, quickly narrows down to two lanes, and enters into a more rural setting.
