context_page_description: King's Highway 23, commonly referred to as Highway 23, is a provincially maintained highway in the Canadian province of Ontario. The route travels from Highway 7 east of Elginfield north to Highway 9 and Highway 89 in Harriston. The total length of Highway 23 is 97.7 kilometres. The highway was first established in 1927 between Highway 8 in Mitchell and Highway 9 in Teviotdale, via Monkton, Listowel and Palmerston. As part of a depression relief program, it was extended south to Highway 7 in 1934. It remained relatively unchanged until 2003, when it was rerouted northward from Palmerston to Harriston.
context_section_description: Highway 23 begins at Highway 7, east of Elginfield, a community straddling the boundary between the municipalities of Middlesex Centre and Lucan Biddulph. The route travels north through the latter, surrounded on both sides by farmland. At Whalen Corners, the highway curves northeast as it exits Middlesex County, becoming the boundary road between Huron County to the west and Perth County to the east. The highway passes through the communities of Woodham and Kirkton, crossing completely into Perth County just north of the latter. It later enters Russeldale, meeting the eastern terminus of former Highway 83
  (County Road 83) as it swerves north. Approximately 9 kilometres (5.6 mi) beyond there it enters the town of Mitchell, where it is known as Blanchard Street. The route intersects Highway 8 (Huron Street), and becomes concurrent with it briefly to cross the North Thames River before branching back northeast along St. George Street. Midway between Mitchell and the village of Monkton, the highway bisects the community of Bornholm within the municipality of West Perth. Prior to entering Monkton, Highway 23 curves gently towards the southeast; In the middle of the village, drivers must turn at an intersection with Perth County Road 55 to remain on Highway 23.
  Continuing its northeasterly course, the highway passes through more farmland, now within the town of North Perth, and serves the communities of Newry and Atwood before encountering former Highway 86 (County Road 86) on the western edge of Listowel. South of this intersection, the route is known locally as Mitchell Road South. It turns southeast onto Main Street West, where it once travelled concurrently with Highway 86 before turning northeast onto Wallace Avenue North. The final leg of the route passes through the village of Gowanstown. The route gently curves to the east before turning north at an intersection just west of Palmerston, where it crosses the boundary into Wellington County and the Town of Minto. Eight kilometres (5 miles) north of the intersection, Highway 23 encounters the western terminus of former Highway 87 (County Road 87), where it turns east then northeast. The route enters Harriston, where it is locally known as Arthur Street. The Highway 23 designation ends at a junction with Highway 9 and Wellington County Road 109 (formerly a segment of Highway 9), locally known as Elora Street. The road continues beyond the junction as Highway 89.
