Interstate 190 (I-190) is an auxiliary Interstate Highway in the U.S. state of South Dakota. The route runs for about 2 miles (3.2 km) south, connecting I-90 to downtown Rapid City. Its length from I-90 to Omaha Street runs concurrent with US 16. It is the westernmost auxiliary route of I-90 (approximately 1,190 miles (1,920 km) east of the highway's western terminus in Seattle, Washington) and its only auxiliary route west of the Mississippi River.
I-190 begins as West Boulevard and has an intersection with Omaha Street, which is signed as US 16/SD 44. US 16 westbound goes east on Omaha Street and eastbound runs north concurrently with I-190. I-190 then becomes a freeway, with an exit to North Street. I-190 then passes under Anamosa Street before an on-ramp from the northbound lanes of West Boulevard. Both US 16 and I-190 then terminate at a trumpet interchange with I-90/US 14/SD 79.
Legally, the route of I-190 is defined at South Dakota Codified Laws § 31-4-203.
