Interstate 190

 

Running concurrent with U.S. 16, Interstate 190 is a short spur from I-90/U.S. 14 south into Downtown Rapid City. U.S. 16 concludes a 500 plus mile route at the trumpet interchange with I-90 in north Rapid City.

Costing $34 million, the I-190/Silver Street Interchange Project reconstructed all of Interstate 190 south from the Anamosa Street overpass to SD 44 (Omaha Street) outside Downtown Rapid City. Started on August 13, 2015, construction rebuilt both roadways of the freeway, including the 1958-built overpasses at Silver Street. The four-phase project included constructing a new single point interchange to replace a split-diamond configuration at Silver Street, redesigning West Boulevard / Nickle Street, and adding new bike paths and sidewalks.¹ A ribbon cutting ceremony for the project was held on August 15, 2017, with the Silver Street Interchange officially opened to traffic three days later.²
