| Iowa 100 (I) |
|
Designated: July 1, 1920 Decommissioned: June 23, 1958 Original western terminus: Griswold; it was extended to US 275 in Council Bluffs on December 22, 1936. Original eastern terminus: US 71 at Lyman Counties: Pottawattamie, Cass Paving history: There were no paved segments at designation. Replaced by: County road, which later became part of IA 48 (north-south alignment in 1923); a relocated IA 92 (at decommissioning) For street alignments in Council Bluffs, see Jeff Morrison's Council Bluffs/Omaha Highway Chronology page. |
| Iowa 100 (II) |
|
Designated: June 23, 1958 Decommissioned: July 1958 Original western terminus: US 6 north of Lewis Original eastern terminus: US 71 south of Atlantic Counties: Cass Paving history: The entire road was paved at the time of designation. Replaced by: IA 414. Jeff Morrison discovered what may be the shortest-lived state highway in Iowa history through newspaper research, as it does not appear on any state highway map. When IA 92 replaced the original IA 100 on June 23, 1958, the five-mile segment of old IA 92 that was not co-signed with US 6 became IA 100. However, motorists were confused that the new IA 100 was so close to the old road, so in late July, the Highway Commission renumbered the road as IA 414. |

| Iowa 101 |

Designated: July 1, 1920 Decommissioned: August 14, 1984 Original northern terminus: IA 5 at Independence; the overlapping segment with IA 11, later IA 150, was deleted on November 3, 1924. Original southern terminus: IA 40 (later US 218) at Vinton Counties: Benton Paving history: At the time of designation, the only paved segment was from Vinton to the Cedar River crossing, dating back to 1912 (the Vinton Eagle on August 20 heralded it as "The First Concrete Roadway in the State of Iowa"). By the end of 1921, it was paved from the south end at IA 40 to the northward turn onto present-day 25th Avenue Drive. (Part of that pavement still exists today along what is now 58th Street Lane.) The rest of IA 101 was upgraded from bituminous to paved in 1955. Major alignment changes: The north-south segment north of the river was moved onto its present alignment on April 2, 1941; it previously followed what is now 58th Street, 25th Avenue Drive, 55th Street Drive, and 25th Avenue in Benton County. Replaced by: IA 150. Former terminus photos IA 101 was the highest number in the original 1920 numbering system, but IA 102 through 107 were designated by the end of the year, as all of those highways appeared on the 1921 map. |

| Iowa 103 |
|
Designated: 1920 (the Highway Commission added it to the primary road system in April, but the date of numbering is unknown) Decommissioned: September 19, 2003 Original western terminus: IA 40 (I), later US 161 and most recently US 218 Original eastern terminus: US 61 in Fort Madison Counties: Lee Paving history: Unpaved at designation, the segment from West Point to Fort Madison was paved in 1938. The segment west of West Point was gravel until 1949, and had a bituminous surface until it was paved in 1988. Replaced by: County Road J40. The DOT had originally planned to take IA 16 east of US 218 instead of IA 103 as part of the legislation passed in 2003, but after reviewing the poor condition of the road, they decided to keep IA 16 in order to resurface it later and give Lee County IA 103 instead.

| Iowa 105 |

Designated: November 20, 1920 Decommissioned: December 12, 1992 (see note below) Original western terminus: IA 15, later US 69, in Lake Mills Original eastern terminus: IA 40, later US 218, in St. Ansgar Counties: Winnebago, Worth, Mitchell Paving history: There were no paved segments at designation. Replaced by: County Road 105 (thanks to Steve Riner for pointing this out in 1998), which is the first county road in Iowa that does not follow the traditional alphanumeric numbering system. It is signed just like any other county road. Note: The date of decommissioning listed was when Mitchell County and the city of Carpenter assumed jurisdiction. Worth County took over its pieces of the road on December 31, 1992. The segment in Winnebago County remained under state control as unsigned IA 971 until the county assumed control of its piece on October 15, 2001; the city of Lake Mills was given its share of the road on July 1, 2003. The segment through Northwood was designated as unsigned IA 972 until July 1, 2003, and the segment through St. Ansgar was designated as unsigned IA 973 until November 5, 2001. Incidentally, IA 105 never did connect with MN 105, which runs from Austin to the state line and continues as County Road S70 in Iowa southward through Otranto to County Road 105 east of Carpenter.

The city of Thornton was scheduled to take over its piece of IA 107 on June 30, 2011, according to the Cerro Gordo County Board of Supervisors' meeting notes from July 12, 2010. Terminus photos |
