Interstate 190 South Dakota

Routing

Interstate 190 is a short spur from Interstate 90 south into Downtown Rapid City. It runs concurrent with U.S. 16 as part of a route to Black Hills National Forest and Mount Rushmore National Monument.

A single point urban interchange (SPUI) was constructed along Interstate 190 at Silver and North Streets from September 2015 to October 2017. Construction included the replacement of the I-190 overpasses above North Street and the removal of the frontage roads south of there. Work also added a bike path along the west side of I-190 to the north. See the interchange layout here.

History

Interstate 190 opened in 1962.2 The bridges over North Street were built in 1958.1 The exchange joining the north end of I-190 with I-90 was reconfigured from a directional T interchange with left ramps into a trumpet interchange in 2000.

The Omaha Street Project, underway during the 2003 and 2004 construction seasons, rebuilt the intersection where I-190 & U.S. 16 ties into Omaha Street (SD 44) and West Boulevard. The public private partnership expanded Omaha Street into a six lane arterial from 12th Street to East Boulevard, with work completed just ahead of schedule on July 3, 2004.3

Construction on the I-190/Silver Street Interchange Project commenced in August 2015 with land clearing. Closure of the southbound lanes of I-190 followed by March 2016 so crews could rebuild them and replace the span above North Street. Phase III reopened the southbound lanes for two-way traffic in October 2016 as the northbound lanes were rebuilt. Phase IV involved paving of Nickel Street (formerly West Boulevard).1

A ribbon cutting ceremony took place on August 15, 2017 and the exchange officially opened to traffic on August 18.4 Total costs were estimated at $32.5 million for SDDOT and $1.7 million for the city of Rapid City. Final projects items for the I-190/Silver Street Interchange Project wrapped up in October 2017.1,4
