South Dakota Highway 28 (SD 28) is a 105.937miles state highway in the east-central South Dakota, United States, that connects Hitchcock, Estelline, and Toronto.
SD 28 was established between 1932 and 1935. It replaced SD 26. It was incrementally extended to its current path.
SD 28 begins at an intersection with U.S. Route 281 (387th Avenue) west of Hitchcock. This intersection, on the line of northwestern Beadle County and southwestern Spink County, is also the eastern terminus of County Road 2 (CR 2; 190th Street). SD 28 takes 190th Street to the east, along the county line. East of 390th Avenue, it enters the northern part of Hitchcock. Just west of 391st Avenue (the southern terminus of CR 13 and the northern terminus of CR 11), it leaves the city limits of Hitchcock.

It ends at the Minnesota state line. Here, the roadway continues to the east as Minnesota State Highway 271 (MN 271).
The only part of SD 28 that is included as part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility and defense, is the small portion concurrent with US 81 near Lake Norden.[2]
SD 28 was established between 1932 and 1935. At that time, it replaced SD 26 and extended from SD 25 west of Bryant to US 77 east of Estelline. In the mid-1950s, it was extended westward. An extension further to the west, to SD 45 north of Miller, may have been signed briefly, but was not indicated as such by 1970. Between 1948 and 1953, it was extended eastward to the Minnesota state line.
