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.
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.

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	Designated: December 6, 1999, to a segment of former US 18 between Clear Lake and Rudd that had been superseded by the Avenue of the Saints bypass. Paving history: The entire road was paved at the time of designation. Major alignment changes: Summer 2000: Connection to US 18 expressway east of Floyd County Road T26 opens. 2001: Segment between the east city limits of Nora Springs and US 18 was turned over to Floyd County; it is now County Road B30. 2003: Truncated east of Mason City's east city limits; Cerro Gordo County agreed to take the road between Mason City and Nora Springs on December 30, 2002, and the DOT approved the transfer on February 18, 2003. (Although I received no confirmation of sign removal after Chris Dobel reported that nothing had changed as of May 16, the county told Jeff Morrison on April 25 that the signs would be down on July 1. Chris Geelhart reported that the east end was posted at the east city limits as of July 2.) The segment through Nora Springs was turned over 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.

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system; from that point onward, IA 123 was an east-west highway between I-35 and IA 28 (SW 42nd Avenue) until it was superseded by a relocated IA 60 (I).
