State Highway 57 is a New Zealand State Highway, linking State Highway 1 north of Ohau to State Highway 3 east of Ashhurst, via Levin, Shannon, Massey University and the southern suburbs of Palmerston North. The highway connects State Highway 1 traffic coming north from Wellington to the city of Palmerston North, and further to the Manawatu Gorge, allowing passage to the eastern side of the North Island and to the twin cities of Napier and Hastings. The highway is classified by the NZTA as a national strategic road.
State Highway 57 broadly follows the route of the North Island Main Trunk railway line to Linton, then follows the route of the Manawatu River for the remainder of its length. For its entire length, the highway is single carriageway with occasional passing lanes and at-grade intersections.
State Highway 57 starts south of Levin, 2 km north of the locality of Ohau. The highway immediately crosses the North Island Main Trunk at level, before heading eastwards on Kimberley Road for two kilometres. SH 57 then turns sharply left onto Arapaepae Road and heads northwards, bypassing and forming the eastern boundary of Levin.
