Next Phase for I-90 and Cliff Avenue Project
As the I-90 and Cliff Avenue project continues, another traffic reroute will be needed. On Thursday evening September 19, at 7 p.m., Cliff Avenue will be closed until 1 a.m. the next morning, according to the South Dakota Department of Transportation.
The closure is needed so the contractor can paint the outside set girders for the I-90 westbound structure over Cliff Avenue.
The interchange ramps will remain open to traffic, and Interstate 90 will remain open, but Cliff Avenue will be closed to thru traffic at the I-90 overpass bridge. The completion date for construction is November 8.
