|
Designated: spring 1924 Decommissioned: July 1, 1980 Original northern terminus: US 34 in central Montgomery County Original southern terminus: Stanton Counties: Montgomery Paving history: Unpaved at designation, it was paved in 1949. Replaced by: County Road M63 Note: IA 120 was shortened from three miles to one mile in 1965, after US 34 was realigned between Hastings and Corning. |

Designated: June 23, 1924 Decommissioned: 1964 Original northern terminus: Dolliver Memorial State Park Original southern terminus: IA 50 west of Lehigh Counties: Webster Paving history: Unpaved at designation, it was paved in 1959. Replaced by: County road (now numbered D33) |
| 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. Replaced by: City streets. While the segment north of US 6 was originally known as "Division Street Road", it followed what is now Pine Street and Cheyenne Avenue. For maps of the route, see the Highways of Davenport and Bettendorf page. |

|
Designated: October 1964 Decommissioned: December 8, 1965 Original northern terminus: North city limits of Clarksville Original southern terminus: IA 10 (now IA 3) Counties: Butler Paving history: The entire road was paved at the time of designation. Replaced by: IA 188. This road was IA 53 (II) until it was superseded by IA 188 in 1949, but the state gave Butler County the segment between Plainfield and Clarksville after paving was completed in October 1964 (the transfer of jurisdiction agreement was reached in June 1963, which may explain IA 122's presence on the 1964 map), leaving the IA 122 designation to the paved segment south of Clarksville. In late 1965, after the transfer agreement was voided due to traffic counts on the decommissioned segment being higher than expected, IA 188's previous alignment was restored (but IA 122 still appeared on the 1966 map). |

| Iowa 123 (I) |
|
Designated: August 18, 1924 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). For maps of the route, see the Highways of Des Moines page. |

Major alignment change: Originally a short north-south spur, IA 124 became an east-west spur from the realigned IA 17 (later IA 4) to Twin Lakes State Park in 1946, replacing part of IA 17 along the way. Replaced by: County Roads D26 (east-west segment) and N57 (north-south segment) at decommissioning Terminus photos (1946-2003 alignment) |

Designated: October 6, 1924 Decommissioned: 1980 (see note below) Original northern terminus: Mitchellville Original southern terminus: IA 7 (later US 32, then US 6) 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. |
