Iowa 180
Designated: December 1, 1930 (number approved October 28)
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).
Replaced by: County Road G48. The piece inside the Hayesville city limits remained part of the state highway system until April 6, 1981. It was created after a reroute of IA 149 in the area.
Iowa 181 (I)
Designated: December 1, 1930
Decommissioned: July 8, 1931
Original western terminus: Riverside
Original eastern terminus: Lone Tree
Counties: Washington, Johnson
Paving history: There were no paved segments.
Replaced by: An extended IA 22
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)
Designated: September 14, 1931
Decommissioned: July 1, 2003
Original northern terminus: IA 5 and IA 92 (originally IA 6 and IA 2, respectively) south of Pleasantville
Original southern terminus: Melcher, which merged with neighboring Dallas in 1986 to form Melcher-Dallas
Counties: Marion
Paving history: Unpaved at designation, it was upgraded from bituminous to paved in 1978.
Replaced by: County Road S45
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.

History
Designated: December 1, 1930 (number approved October 1), from Ute to US 75 east of Mondamin
Paving history: There were no paved segments at designation.

  • 1956: Last original segment, from Moorhead to Pisgah, was paved; all future extensions were paved.

    • Major alignment changes:
  • October 25, 1968: Extended southward to US 30 in Missouri Valley, replacing part of US 75 after it was routed onto I-29.
  • 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.
  • July 1, 2003: Southernmost 31 miles between IA 127 and the north city limits of Council Bluffs decommissioned, eliminating a 1½-mile multiplex with 127; the segment south of 127 is now County Road L20. This truncation removed IA 183 from Pottawattamie County and brought it back to its original 1930 routing.

    Iowa 188
    Length: 24 miles/39 kilometers
    Western terminus: IA 3 south of Clarksville
    Eastern terminus: US 63 in northern Bremer County
    Terminus photos

    Counties: Butler, Bremer
    Cities along route: Clarksville, Plainfield
    History
    Designated: June 13, 1945, from US 218 at Plainfield to US 63
    Paving history: There were no paved segments at designation.
  • 1949: Paved segment from IA 3 to Clarksville added
  • 1955: Paved from US 218 to US 63
  • 1964: Last segment, from Clarksville to US 218 at Plainfield, paved.
    • Major alignment changes:
  • August 16, 1949: Extended westward and southward from US 218 to IA 3, superseding the old IA 53 (II) spur to Clarksville.
  • October 1964: Truncated west of Plainfield, as the newly-paved segment between Plainfield and Clarksville was given to Butler County, while the paved segment between Clarksville and IA 3 (essentially, the old IA 53) became IA 122 (II). (An agreement between the state and Butler County was reached on June 28, 1963, probably explaining its absence from the 1964 map, but didn't become reality until the state paved the last unpaved segment in 1964.)
  • December 8, 1965: Extended from US 218 to its previous end at IA 3 after the Highway Commission confirmed that the 1963 transfer agreement was voided due to higher-than-expected traffic counts. (At the time, the state was able to transfer a highway to a county if average traffic counts dropped below 400 vehicles a day, but the Des Moines Register on November 1, 1964, reported that counts averaged from 500 to 600 vehicles a day.)

    Original western terminus: US 34/275 (Main Street & 9th Avenue) in Council Bluffs
    Original eastern terminus: US 34/275 southeast of Council Bluffs, near the Iowa School for the Deaf. The original alignment in Council Bluffs, starting at South 9th Avenue, followed Main Street, 16th Avenue, 7th Street, 25th Avenue, and Main Street (now the South Expressway) again.
    Counties: Pottawattamie
    Paving history: There were no paved segments outside of Council Bluffs at designation; a short piece outside of the Council Bluffs city limits was paved in 1957.
    Major alignment changes:
  • 1932: Truncated at the original Council Bluffs airport (which was near where the I-29/US 275 interchange is today).
  • January 30, 1935: South end moved to Lake Manawa State Park; the former east-west segment would become part of IA 367 in 1939.
  • July 1, 1971: Extended northward along part of the former IA 375 (a former US 275 segment) to US 6 (West Broadway), following South 9th Avenue and 4th Street.

  • July 1, 1980: Resurrected as a route running southward from I-29 along North 16th Street (a former US 75 segment), West Broadway (sharing US 6), the South 6th and 7th Street one-ways, and the four-lane South Expressway, ending at I-29/80.

However, the route remains part of the National Highway System as a non-primary road.
    • Replaced by: City streets. The original alignment replaced the short-lived IA 241 (I).

    Original eastern terminus: Plover
    Counties: Pocahontas
    Paving history: Unpaved at designation, the road was paved in 1956.

    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.
