Decommissioned: August 26, 1980
Original western terminus: Hayesville
Original eastern terminus: IA 149
Counties: Keokuk
Paving history: There were no paved segments at designation, and the road had a bituminous surface at the time of decommissioning (but has since been paved).

Decommissioned:
July 8, 1931
Original western terminus: Riverside
Original eastern terminus: Lone Tree
Counties: Washington, Johnson
Paving history: There were no paved segments.

Note: The Highway Commission approved IA 181 as a spur from Riverside to US 161 (created from a former piece of 161) on October 28, 1930, and the extension eastward to Lone Tree was approved on October 29. The entire road was not signed until December 1.
Iowa 181 (II)

Paving history: Unpaved at designation, it was upgraded from bituminous to paved in 1978.

Note: IA 181 was missing from the 1981 state transportation map, but whether this was because of a short-lived decommissioning or a map error is currently unknown. It was back on the 1983 map. The road continued to appear on route logs during this era and no mention of a transfer of jurisdiction during that timeframe was made in the legal description.

  • November 19, 1969: Extended further southward, along the old US 30A, from Missouri Valley to Council Bluffs.
  • October 20, 1981: Southernmost 1½ miles between US 6 and the north city limits of Council Bluffs were turned over to the city.

This truncation removed IA 183 from Pottawattamie County and brought it back to its original 1930 routing.

    History
    Designated: June 24, 1931, to the former IA 241 (I) between downtown Council Bluffs and a junction near the Iowa School for the Deaf, with both ends at US 34/275.

    Iowa 196
    Designated: April 9, 1935
    Decommissioned: June 14, 2016
    Original northern terminus: US 20 in Sac City
    Original southern terminus: US 71 east of Lake View
    Counties: Sac
    Paving history: Unpaved at designation, the road was paved in 1955.
    Major alignment changes:
  • 1952: Straightened to intersect US 20 east of Sac City prior to paving. The previous alignment left Sac City via Highland Avenue and followed what is now Shasta Avenue and 270th Street.
  • November 19, 2012: Extended northward to the new interchange with US 20 along part of County Road N14 after the US 20 expressway segment between US 71 and IA 4 opened.
    Replaced by: A relocated US 71. Incidentally, IA 196 was designated after US 71 was realigned away from Sac City, but it did not replace any of it as US 71 originally followed present-day County Road M54 between Sac City and a point east of Lake View.
    Note: The IA 196 number was originally assigned to a planned spur route from US 20 to Williams as part of a plan to relocate US 20 in Hamilton and Hardin counties. US 20 would have continued eastward from the point where the route turned northward toward Williams (which is County Road R75 now) toward US 65; part of the proposed route incorporated the present-day County Road D25. IA 196 would have replaced part of US 20 south of Williams. The number was approved on October 28, 1930, but the plan to relocate US 20 was officially scrapped on May 25, 1932, and the IA 196 number would not be used again until 1935.
