South Dakota Highway 42

The westernmost segment of SD 42 begins at a junction with U.S. Route 281 (US 281) and travels east through open farmland. This is the shortest of the three segments; it is only about {{convert|6|mi|km|spell=in}} long, and it ends as the roadway crosses from Aurora County into Davison County.{{google maps|url=https://maps.google.com/maps?saddr=US-281+N%2F388th+Ave&daddr=Co+Rd+60%2F265th+St&hl=en&ll=43.54158,-98.384628&spn=0.145338,0.338173&sll=43.558252,-98.281975&sspn=0.145298,0.338173&geocode=FXZkmAIdXu0h-g%3BFWRmmAIdHLUj-g&oq=Davison&mra=dme&mrsp=1&sz=12&t=m&z=12|accessdate=December 20, 2013|title=Western segment of SD 42}}

The central segment of the highway begins at an intersection with SD 37 in rural Davison County. It heads east and crosses the BNSF Railway.{{cite web|url=http://www.sddot.com/transportation/railroads/docs/railmap.pdf|title=Official South Dakota Rail Map|publisher=South Dakota Department of Transportation|date=October 2009|accessdate=December 20, 2013}} Just east of the railroad, the route passes through the town of Ethan, then enters Hanson County. About {{convert|6|mi|km|spell=in}} farther east, SD 42 bends slightly to the south and crosses the James River. The highway continues east through the flat prairie and enters McCook County.

About {{convert|5|mi|km|spell=in}} east of the county line, the highway enters the city of Bridgewater. Here, it curves to the northeast and crosses another branch of the BNSF Railway before meeting the eastern terminus of SD 262. SD 42 then curves back to the east and leaves Bridgewater. It continues through flat farmland, intersecting US 81 and passing over the west fork of the Vermillion River. The route heads east about {{convert|10|mi|km|spell=in}} before crossing the east fork of the Vermillion River, and then entering Minnehaha County.

In Minnehaha County, SD 42 intersects SD 19, and the two highways run east for about {{convert|1|mi|km|spell=in}} before SD 19 splits off to the north, and SD 42 continues east toward Sioux Falls. It intersects the northern terminus of SD 17 approximately {{convert|3|mi|km|spell=in}} west of the city. The central segment of SD 42 ends at Ellis Road near the Sioux Falls city limits.{{google maps|url=https://maps.google.com/maps?saddr=SD-37+N%2F410th+Ave&daddr=SD-42+E%2FW+12th+St%2F265th+St&hl=en&ll=43.516689,-97.443237&spn=0.581591,1.352692&sll=43.52341,-96.868858&sspn=0.145382,0.338173&geocode=FYJrmAId3Y4o-g%3BFVhtmAId53o6-g&oq=Siou&mra=dme&mrsp=1&sz=12&t=m&z=10|accessdate=December 20, 2013|title=Central segment of SD 42}}

The easternmost segment of SD 42 begins at Six Mile Road east of the city of Sioux Falls. It runs southeast, concurrent with SD 11 along Arrowhead Parkway. The two highways pass by a golf course and a park before crossing the Big Sioux River. East of the river, SD 11 turns to the north toward Brandon, and SD 42 curves to the east. The highway passes through the unincorporated community of Rowena before curving due south and crossing the Iowa state line. The route continues into Iowa as Iowa Highway 9.{{google maps|url=https://maps.google.com/maps?saddr=SD-11+N%2FSD-42+E&daddr=SD-42+E&hl=en&ll=43.504986,-96.563988&spn=0.145426,0.338173&sll=43.496394,-96.563129&sspn=0.072723,0.169086&geocode=FSxPmAIdEIk9-g%3BFUzDlwIdWmY_-g&oq=Grand+F&mra=dme&mrsp=1&sz=13&t=m&z=12|accessdate=December 20, 2013|title=Eastern segment of SD 42}}
