North of the Iowa River, Iowa 965 straightened out and headed due north towards Swisher, intersecting Johnson County Road F12. It entered Linn County, where it is no farther than away from Interstate 380 until the former Iowa 965's northern end in Cedar Rapids. Shortly after entering Linn County, the highway entered the Cedar Rapids city limits. Sixth Street SW, as it is known in Cedar Rapids, intersects Wright Brothers Blvd SW, formerly Iowa Highway 84, which connects to The Eastern Iowa Airport. As Cedar Rapids nears, Sixth Street SW passes through a light industrial zone, flanked to the west by an Archer Daniels Midland corn processing plant. Prior to 2003, Iowa Highway 965 ended at an interchange with US 30 / US 151 / US 218.
