Route description
I-90 enters South Dakota in
The route then enters
I-90 then continues through Aurora County (connecting to White Lake and Plankinton), Davison County (where Mt. Vernon, Mitchell, and the Corn Palace are located), Hanson County (Alexandria), and McCook County (Salem). Then comes the state's most populous county, Minnehaha. After passing the communities of Humboldt and Hartford, the Interstate intersects the only other major Interstate in the state, I-29, at Sioux Falls, the largest city. Just east of I-29 is where I-90 meets the northern terminus of I-229. East of Brandon and northeast of Valley Springs, it then ends its trip through South Dakota of 413 miles (665 km) before entering Minnesota and Rock County, just west of the towns of Beaver Creek and Manley.
Since April 2015, the speed limit is 80 mph (130 km/h) between the Rapid City and the Minnesota state line, except for the segment between I-229 and Marion Road in Sioux Falls, where the speed limit is 65 mph (105 km/h). The speed limit remains 75 mph (121 km/h) between Rapid City and the Wyoming state line.
Codified law
The South Dakota section of I-90 is defined at South Dakota Codified Laws § 31-4-184.[2]
Transit
Jefferson Lines provides intercity bus service along the length of I-90 in South Dakota serving seven communities along the route with major transfer points at the Sioux Falls Bus Station and in Vivian.[3]
History
I-90 was constructed in the 1970s. The four-lane Interstate replaced old US 16 as the main road connecting Rapid City and Sioux Falls. Much of Old US 16 remains intact; however, I-90 has absorbed sections and likewise has reshaped the economies of many southern South Dakota towns.[4] Driver-oriented businesses and hotels opened near new exits on I-90, along with roadside attractions to lure in tourists.[5] The final section of I-90 in the state opened in November 1976 between the Wyoming state line and Spearfish.[6]
On May 24, 2012, the South Dakota Transportation Commission declared the entire length of I-90 as part of the National Purple Heart Trail, naming it the Purple Heart Memorial Highway, named after the military decoration of the same name.[7]
