South Dakota Highways

SD 89 SD 101

In the U.S. state of South Dakota, Interstate 90 traverses east–west through the southern half of the state.

Route description[edit]

Interstate 90 enters South Dakota in Lawrence County as a four lane divided highway. It enters concurrently with U.S. Route 14, and passes through the town of Spearfish, where it shares another concurrency with U.S. Route 85 from exit 10 to exit 17. From there it passes several miles east and north of the tourist town of Deadwood before entering Meade County, going just to the west of Sturgis and picking up a concurrency with South Dakota Highway 79. The freeway generally passes along the north and east edges of the Black Hills.

The route then enters Pennington County, where it passes through the northern edge of Rapid City, gateway to the Black Hills and the nearest passing to the Mount Rushmore National Memorial. Rapid City is also where the interstate has its westernmost auxiliary route, Interstate 190, which links the interstate to the western edge of the downtown area, also bringing SD 79 into the city. From Rapid City, the route heads east, passing between Box Elder to the south and Ellsworth Air Force Base to the north before heading towards Wall on to Jackson County. The exits for Badlands National Park to the south are within 15 miles (24 km) either way of the county line. The concurrency for US-14 also ends just east of Wall.

The Lake Francis Case portion of the Missouri River viewed from a rest stop just south of Chamberlain; the pre-interstate Chamberlain Bridge is in the center.

From there, the route passes mostly east-west through Jackson and Jones counties. Interstate 90 enters Central Time in entering Jones County. It is in Lyman County, at Exit 212 in Vivian, that the highway provides its closest link to the capital city of Pierre, along U.S. Route 83, some 35 miles (56 km) north. The road crosses the Missouri River at Lake Francis Case, between the towns of Oacoma and Chamberlain, also crossing into Brule County.

It then continues through Aurora County, Davison County (where Mitchell and the Corn Palace are located), Hanson County, McCook County, and Minnehaha County. In Minnehaha County, the interstate intersects the only other major interstate in the state, Interstate 29, at Sioux Falls. Just east of Interstate 29 is where Interstate 90 meets the northern terminus of Interstate 229. It then ends its 412 miles (663 km) trip through South Dakota northeast of Valley Springs before entering Minnesota and Rock County, just west of the towns of Beaver Creek and Manley.

Codified law[edit]

The South Dakota section of I-90 is defined at South Dakota Codified Laws § 31-4-184.[2]

History[edit]

Removal of exit 66[edit]

An older version of the I-90 shield as used in South Dakota, still commonly seen along the route

In the city of Box Elder, exit 66, which crossed South Dakota Highway 435, was closed on October 1, 2003. The partial cloverleaf interchange of exit 66 was also demolished. Since the closure, local citizens and officials feared the lack of entrances which access the Ellsworth Air Force Base. However, the move was made to emphasize their concerns regarding to commercial development and its concisions with the Ellsworth forces. Exit 67, which was constructed not too long before the closure of exit 66, is now used as the main entrance and exit feeder to the base.[3]
