SOUTH DAKOTA HIGHWAY 115

'South Dakota Highway 115' was created from the routing of US 77, "Old 77", when its alignment was moved west to become Interstate 29 around 1980 and SD-15's route from U.S. Route 18 to Sioux Falls. SD-115 routes from its intersection with US 18 about 13 miles south of Sioux Falls to Interstate 29 3 miles west of Dell Rapids.
SD-115 was designated a POW/MIA Memorial Highway in 2000. The segment south of Sioux Falls to US 18 was originally designated part of the Custer Battlefield Highway when it was designated SD-15.
