Route description

SD 258 begins at a diamond interchange with exit 308 of I-90 and travels north. The route enters the city of Plankinton almost immediately and continues north. The highway turns east onto Davenport Street in Plankinton and a curve takes the highway to the northeast. After leaving Plankinton, the road curves back to the east and continues through open plains for about one mile (1.6 km) before reaching its eastern terminus at an intersection with US 281. The roadway continues east of this intersection as County Road 34.[2][3]
