Paving history: Unpaved at designation, it was paved in 1949.

Iowa 122 (I)
Designated: June 23, 1924
Decommissioned: July 1, 1960
Original northern terminus: IA 74 (later IA 150) near Davenport
Original southern terminus: US 6 at the "Five Points" intersection (Division and Locust Streets and Hickory Grove Road) in Davenport. It was truncated to the relocated US 6 at Kimberly Road on April 14, 1937; on September 2, 1937, it was extended southward to end at US 61 via Division, Locust, Marquette, and 2nd Streets to Gaines Street. On December 10, 1957, the 2nd Street segment was removed and IA 122 followed Marquette to the relocated US 61 at River Drive.
Counties: Scott
Paving history: The entire road was paved at the time of designation. The 1937 extension was originally unpaved but the Highway Commission ordered paving of this segment shortly after the extension.

Designated: 1963
Decommissioned: 1966
Original northern terminus: Clarksville
Original southern terminus: IA 10 (now IA 3)
Counties: Butler
Paving history: The entire road was paved at the time of designation.

This road was IA 53 (II) until it was superseded by IA 188 in 1949, but Butler County took over the gravel segment between Plainfield and Clarksville in 1963, leaving the IA 122 designation to the paved segment south of Clarksville. In 1966, once the Plainfield-to-Clarksville segment was paved, IA 188's previous alignment was restored.

History
Designated: December 6, 1999, to a segment of former US 18 between Clear Lake and Rudd that had been superseded by the Avenue of the Saints bypass.

Major alignment changes:

The segment through Nora Springs was turned over to the city in a separate move on July 1 after legislation to allow its decommissioning was passed. The old segment became an extension of County Road B30.

    Decommissioned: June 13, 1959
    Original northern terminus: Grand Avenue (posted as US 32, then US 6, then IA 90) in Des Moines. By 1936 it was duplicated with IA 90 along Grand Avenue to end at 9th Street (which was US 65/69 at the time), although the Grand Avenue segment may have been removed by the time that the 18th Street/Fleur Drive segment was removed.
    Original southern terminus: Army Post Road (posted as IA 28, then IA 60) in Des Moines. In 1957 it was extended westward along an extension of Army Post Road to the future interchange with I-35.
    Counties: Polk
    Paving history: Unpaved outside of Des Moines at designation, the entire road was paved in 1925.
    Note: On November 18, 1958, the north-south segment (following 18th Street and Fleur Drive) was removed from the state highway system; from that point onward, IA 123 was an east-west highway between I-35 and IA 28 (SW 42nd Avenue) until it was superseded by a relocated IA 60 (I).
    Replaced by: City streets (north-south segment in 1958); IA 60 (I) (east-west segment in 1959).

    Original southern terminus: US 34
    Counties: Henry
    Paving history: Unpaved at designation, it had a bituminous surface at decommissioning (but has since been paved).

    Counties: Polk
    Paving history: The entire road was paved at the time of designation.
    Replaced by: unsigned County Road S27
    Note: The legal description noted that Polk County and the city of Mitchellville took over the road on March 9, 1981, but IA 126 did not appear on the 1981 map (which noted the status of state highways as of October 1980), so it may have been demoted to an unsigned highway at the time that the segment of US 6 between Altoona and Newton was moved onto I-80.
