| Iowa 362 (I) |
|
Designated: November 23, 1938 Decommissioned: 1980 Original western terminus: Macedonia Original eastern terminus: US 59 in southern Pottawattamie County Paving history: Unpaved at designation, the road was paved in 1956. Replaced by: County Road G66 |
| Iowa 362 (II) |
|
Designated: 1980 Decommissioned: July 1, 2003 Original western terminus: DeSoto Bend National Wildlife Refuge Original eastern terminus: I-29 (exit #72) west of Loveland Paving history: Unpaved at designation, it had a bituminous surface at decommissioning and remains that way today. However, some maps (Rand McNally, for instance) incorrectly showed it as a four-lane extension of I-680. With IA 362's decommissioning, there are no longer any unpaved state highways. Replaced by: County Road G12. Terminus photos |
| Iowa 363 |
|
Designated: February 1, 1939 (number approved December 6, 1938) Decommissioned: July 1, 2003 Original western terminus: IA 11, later IA 150, in northeast Benton County Original eastern terminus: Urbana Paving history: Unpaved at designation, the road was paved in 1955. Major alignment change: In 1984 it was converted from a spur into Urbana to a connecting road between IA 150 and the newly-completed I-380; the old segment that ended in town was unsigned IA 919 until 1995. Replaced by: Local road. IA 363 replaced IA 92 (I); although it was absent from state transportation maps after 1991, it was probably due to the lack of space on the map as the road was fully signed until its decommissioning.

Designated: January 17, 1939 Decommissioned: 1981 Original northern terminus: IA 92 in eastern Marion County Original southern terminus: Tracy Paving history: Unpaved at designation, the road was paved in 1960.

| Iowa 368 (II) |
| This was the designation for two former half-mile segments of IA 5 that were bypassed by a parallel four-lane road to the north that opened on December 13, 2002. One segment ran along the north city limits of Hartford between a point west of Vine Street and 215th Street; the other was a dead-end segment northwest of Pleasantville. After the Pleasantville bypass opened, the designation was also given to the rest of the bypassed IA 5. On July 13, 2004, the Transportation Commission approved the transfer of Hartford's portion of IA 368 to the city. The Pleasantville segment was transferred to local jurisdictions by the end of 2004, but the DOT's 2007 Warren County map still shows one piece of IA 368 near Hartford, meaning that the transfer to Warren County may not have been completed yet. |

The Mahaska County Board of Supervisors agreed to take over IA 371 on December 23, 2002; the DOT approved the transfer on January 14, 2003, and signs had been taken down by June 28. Terminus photos |
