History
|
Designated: October 23, 1930, replacing IA 16 (I).
Paving history: At the time of designation, these segments were paved: IA 9 to Algona, the Humboldt/Webster county line to Fort Dodge, a point south of US 20 to IA 91 (now 175), the split with IA 17 (now 141) near Bouton to IA 7 (now 44) north of Adel, and from US 34 in Union County (including the multiplex) to the Union/Ringgold county line
1931: Paved from IA 7 to Adel and from Winterset to US 34
1932: Paved from IA 91 to US 30 (including the multiplex) at Ogden
1933: Paved from the city of Humboldt to the Humboldt/Webster county line and from US 20 to a point south of Fort Dodge (on a new diagonal alignment)
1935: Paved from Algona to the Kossuth/Humboldt county line
1936: Paved from the Kossuth/Humboldt county line to Humboldt and from the North River crossing in Madison County to Winterset
1938: Paved from the Union/Ringgold county line to Mount Ayr
1940: Paved from the Minnesota state line to IA 9 (on a new alignment, creating IA 91 (II) to serve Ledyard; the old alignment also followed what is now County Road P50 between Ledyard and IA 9). It was also paved from County Road G (now E57) south of Ogden to IA 141.
1947: Paved from De Soto to the North River crossing
1951: Paved from Adel to De Soto on a straightened alignment that included a new bridge across the Raccoon River. (The old alignment followed what is now 323rd Place and 330th Lane north of the river, and part of Overton Place south of the river. The old bridge was removed.)
1955: Last segment, from IA 2 west of Mount Ayr to the Missouri state line, paved
Major alignment changes:
November 18, 1960: Re-routed to the west of Fort Dodge (it had run into the city center); the old segment was redesignated as IA 413 and an extended IA 320.
December 1976: Re-routed south of IA 92 along a new two-lane road that ended south of the junction of County Road G61. The old route south of Winterset is now County Road P71.
June 3, 1977: Bypass to the west and south of Winterset (with IA 92) opened, taking US 169 off 1st Street (John Wayne Drive).
November 19, 1990: Expressway segment between Webster County Road D20 and the relocated US 20 completed, connecting it with an existing segment between there and IA 7.

Business US 169
|
|
Fort Dodge: The second of two business US routes in Fort Dodge
was designated along parts of IA 7 (2nd Avenue South and South 8th Street) and US 20 (Kenyon Road) after the US 20 expressway opened and IA 7 was truncated in 1990. AASHTO officially approved the Business US 169 designation on April 21, 1996. Designated as IA 926 until the Transportation Commission approved the transfer of jurisdiction to the city of Fort Dodge on November 4, 2014, it shares about two of its three miles with Business US 20 heading out of downtown Fort Dodge. After the city took over jurisdiction of Business US 169, the Cross-Town Connector Project shifted it from 2nd Avenue to 1st Avenue a block to the north. (Terminus photos)
