The western terminus of SR 446 is at a T-intersection with U.S. Route 224 (US 224) in Canfield, approximately one mile (1.6 km) west of the downtown area.

Created in the middle of the 1980s, SR 446, which runs entirely within Mahoning County, is a two-lane highway that bypasses Canfield to the southwest.

Abutted by forested lands with a few commercial businesses scattered along the way, SR 446 bends to the southeast, and arrives at its junction with US 62, a signalized intersection.

Continuing southeast, the route passes a house, then meets the Mill Creek Metroparks Bikeway.

Further southeast, it passes more commercial buildings, and is then bounded by farmland on the south side affiliated with Mill Creek Metroparks.
