Iowa 140
Length: 25 miles/40 kilometers
Northern terminus: IA 3 near Remsen
Southern terminus: US 20 in Moville
Terminus photos

Counties: Woodbury, Plymouth
Cities along route: Remsen, Kingsley, Moville
History
Designated: October 16, 1926, to the former IA 30 between Remsen and Moville
Paving history: There were no paved segments at the time of designation.
  • 1946: Paved from Kingsley to Moville
  • 1958: Extension from US 75 to I-29 west of Sloan paved
  • 1960: Paved from Sloan to Hornick (which eventually became part of IA 141). All other segments were unpaved after they were turned over; the extension in 1980 was entirely paved.

  • Major alignment changes:
  • May 27, 1931: Extended southward to Hornick and then westward to Sloan (where it ended at US 75), replacing IA 192 (I).
  • 1958: Extended westward from Sloan to the newly-completed I-29
  • 1961: Segment between I-29 and Hornick superseded by IA 141
  • 1964: Segment from Moville to Hornick decommissioned (now signed as County Road K64)
  • 1965: Truncated north of Kingsley
  • July 1, 1980: Segment between Remsen and Kingsley recommissioned (it was County Road R, later L14, up to that point)
  • Iowa 141
    Length: 156 miles/251 kilometers
    Western terminus: I-29 (exit #127) near Sloan
    Eastern terminus: I-35/80 (exit #127) on the Grimes/Urbandale border
    Not only is IA 141 one of two non-Interstate highways to begin and end at Interstates (IA 192 is the other), but the exit numbers at both endings are the same!

    Cities along route: Sloan, Hornick, Smithland, Mapleton, Ute, Charter Oak, Denison, Aspinwall, Manning, Dedham, Coon Rapids, Bayard, Bagley, Perry, Granger, Grimes, Urbandale

    NHS: From US 169 east of Perry to I-35/80
    Expressway segment: 26 miles, from IA 144 in Perry to the eastern terminus at I-35/80. This segment was named the George Soumas Memorial Highway in early 2013 in honor of George P. Soumas (1915-1994), a World War II veteran and former mayor of Perry who led the community effort to encourage the completion of this expressway.
    Exit lists: Segment from Perry to I-35/80
    Multiplexes:
  • 10 miles with US 59 in Crawford County through Denison; this includes a half-mile triplex with US 30 in Denison.
  • 3 miles with US 71 in southern Carroll County near Templeton
  • 3 miles with IA 25 east of Bayard

  • (Also worth mentioning: IA 141 and IA 175 share about half a mile in Mapleton, but this is a "wrong-way" multiplex; the two highways run in opposite directions.)
    History
    Designated: October 16, 1926, replacing IA 23 (I) west of downtown Sioux City and IA 34 between downtown Sioux City and Denison

  • 1952: Paved from IA 25 east of Bayard to Bagley
  • 1955: Paved from IA 89 south of Woodward to Granger
  • 1956: Paved from Coon Rapids to Bayard (on an new alignment; the old one followed present-day County Road E63). The last segment south of Granger was paved as part of an alignment change in 1958 (see below).

  • Notes
    The 21-mile segment between Le Grand and Grinnell was mistakenly left off the 2000 official state transportation map; however, DOT officials assured that the highway was not decommissioned or modified. The symbols remained on the map, but the road itself was left off. It does appear in 2001 and subsequent editions.
    Iowa 147
    Designated: October 16, 1926 Decommissioned: July 1, 2003

    Iowa 150 (II)
    Designated: October 28, 1930 Decommissioned: December 1, 1930
    Original northern terminus: Schleswig
    Original southern terminus: IA 141 north of Denison
    Paving history: There were no paved segments.
    Replaced by: An extension of IA 21 (I). While this number was approved at a Highway Commission meeting on October 24, the Commission approved the IA 21 extension from Ida Grove to Denison, which superseded this incarnation of IA 150, on November 12. The IA 21 extension became official on December 1, which was the date that this version of IA 150 was supposed to take effect. Thus, it is unknown whether this short-lived highway was signed.
    Iowa 150 (III)
    Designated: May 27, 1931 Decommissioned: 1941
    Original northern terminus: US 30 in Jefferson
    Original southern terminus: IA 46 (now IA 141) east of Bagley; it was extended southward to IA 7 (now 44) at Panora on December 6, 1938, engulfing most of IA 271 (II) along the way.

    Terminus photos

    Counties: Winneshiek, Fayette, Buchanan, Benton
    Cities along route: Calmar, West Union, Fayette, Maynard, Oelwein, Hazleton, Independence, Urbana, Vinton

    Multiplexes:
  • 2½ miles with IA 3 north of Oelwein
  • History
    Designated: September 1941 (number approved June 9), replacing IA 11 between Calmar and Cedar Rapids, and IA 74 (I) between Tipton and Davenport, sharing segments of US 30 (about 27 miles in 1951) and IA 38 (8 miles) in between. This road was intended to be an extension of US 150, which was announced by the Highway Commission in June 1941, but was never signed as such in Iowa. However, according to Dale Sanderson's site, the Centennial Bridge was originally co-signed as US 67 and US 150, with the latter transitioning into IA 150 at the foot of the bridge. (The bridge was owned by the city of Rock Island until 2005, so any US 150 signage on the Iowa side of the bridge likely came from Illinois.) IA 150 ended there until its truncation in 1969.
    Paving history: At the time of designation, the entire road was paved except for the segment from Calmar to West Union. That segment was bituminous until it was paved in 1958.
    Major alignment changes:
  • November 10, 1953: Rerouted between Cedar Rapids and Lisbon, with US 30, when the US 30 cutoff opened.
  • November 1958: Rerouted away from downtown Cedar Rapids by following 50th Street (now Collins Road) along the city's northeast side, US 151 through Marion, and the former IA 94 (I) from Marion to Mount Vernon.
  • 1961: Rerouted through Marion by following US 151 and a new road south of IA 13 to Mount Vernon Road. The old segment through Squaw Creek Park was removed, while the rest of the old diagonal segment (Bloomington Road in Linn County) is still gravel today.
  • November 24, 1965: Re-routed along a new road south of Mount Vernon Road to US 30; it followed US 30 from this point eastward to IA 38 at Stanwood. Five miles of the old segment northwest of Mount Vernon was unsigned IA 974 until 1980; all of the old segment is now County Road E48.
  • January 1, 1969: Decommissioned southeast of Cedar Rapids; the standalone segment between US 151 and US 30 became part of an extended IA 13, and the standalone segment between Tipton and Davenport (the former IA 74) became IA 130.
  • August 14, 1984: Re-routed along the former IA 101 in Benton County to US 218 in Vinton. Collins Road in Cedar Rapids became IA 100 at the same time, and the segment through Walker to Center Point became IA 920. The Center Point-to-Hiawatha stretch, which closely paralleled the new I-380 segment which opened that day, became County Road W6E upon decommissioning.

  • For other alignment changes in Davenport that are not listed here, see the Highways of Davenport and Bettendorf page.
  • Notes
    Plans to upgrade IA 150 between Independence and Oelwein to "Super-2" status were delayed in September 2001 as a result of state funding shortages. A planning study for this route had been included in the 2001-2005 transportation plan.
    Iowa 151
    Designated: October 16, 1926 Decommissioned: January 1, 1938
    Original western terminus: US 71 in Auburn
    Original eastern terminus: IA 17 (now IA 4) east of Lake City
    Paving history: There were no paved segments at designation. The segment from Lake City to IA 17 was paved in 1936, but the segment west of Lake City remained unpaved at decommissioning.
    Replaced by: IA 188 (II); this highway replaced part of IA 35 (I). The number was reassigned to US 151.
    Iowa 152 (I)
    Designated: September 20, 1926 Decommissioned: 1980
    Original northern terminus: Murray
    Original southern terminus: US 34 in western Clarke County
    Paving history: Unpaved at designation, it was upgraded from bituminous to paved in 1971.
    Replaced by: County Road R16. It was created from a realignment of the former IA 8 (I) just before it became US 34. The three-quarters-of-a-mile segment through Murray was maintained by the state as unposted IA 929 until July 1, 2003.
    Note: The original IA 152, as laid out in the Highway Commission's Service Bulletin in the fall of 1925, was supposed to have replaced part of IA 17 (I) between US 30 near Grand Junction and IA 16 east of Perry. However, that road was not renumbered until it became part of IA 144 in 1941.

    Designated: December 1, 1930 (number approved November 11) Decommissioned: July 15, 1957
    Original northern terminus: Oakdale (now part of Coralville); it was extended to US 218 near North Liberty in 1931
    Original southern terminus: US 6 near Coralville
    Paving history: There were no paved segments.
    Replaced by: A realigned US 218 between North Liberty and Oakdale, and local roads between Oakdale and US 6. (Most of that alignment, 25th Street in Coralville, has since been removed although a small piece of 25th Street still exists near Coral Ridge Mall.) Part of the old US 218 alignment became IA 153 (III).
    For maps of the route, see the Highways of Iowa City page.
    Iowa 153 (III)
    Designated: July 15, 1957 Decommissioned: 1969
    Original northwestern terminus: US 218 in Johnson County
    Original southeastern terminus: North Liberty
    Paving history: The entire road was paved at the time of designation.

    Iowa 155 (I)
    Designated: October 18, 1927 Decommissioned: April 16, 1931
    Original western terminus: Commerce, now part of West Des Moines
    Original eastern terminus: IA 28 (SW 9th Street) south of Des Moines (at the time, it was a half-mile south of the city limits). One map I have seen showed it ending at US 65/69 (which followed Indianola Avenue at the time) before it was decommissioned.
    Paving history: There were no paved segments.
    Replaced by: County Road X, now local roads. The bridge that it followed across the Raccoon River was removed after flooding washed it out in 1965. The route followed present-day Walnut Woods Drive and Browns Woods Drive in West Des Moines as well as McKinley Avenue in Des Moines (except for a portion of the road that was removed to make room for the Des Moines Airport). For a map of the route, see the Highways of Des Moines page.
    Iowa 155 (II)
    Designated: February 14, 1933 Decommissioned: 1980
    Original northern terminus: US 34 in western Adams County; in 1965 the northernmost 1½ miles were truncated after US 34 was realigned.
    Original southern terminus: Nodaway
    Paving history: Unpaved at designation, the entire road was paved in 1955.
    Replaced by: County Road N26, plus one block of 8th Avenue and one block of 3rd Street in Nodaway.

    Iowa 157 (I)
    Designated: February 28, 1928 Decommissioned: December 1, 1928 (or sometime before 1931)
    Original western terminus: South city limits of Monticello
    Original eastern terminus: US 161 south of Monticello
    Paving history: There were no paved segments.
    Replaced by: Unknown; it could have been replaced by IA 113 (I), or it could have also reverted to local control before the number for the second IA 157 was assigned. This 800-foot highway, which was referenced in Highway Commission meeting notes in February 1928, may not have been signed because of its short length, and it never appeared on maps. The October 29 Highway Commission meeting notes did not mention any changes to this highway when the extension of 113 was approved. This highway, which is now inside Monticello's city limits, followed present-day Cedar Street southward to Main Street in Monticello, while IA 38 currently follows Cedar and 1st Streets to Main Street.
