(July 1, 1920-October 1940)
- In 1920, they knew it as: A connection from Dayton to the north-south route running through Webster County
- We know it as: IA 175 between the east US 169/IA 175 junction and Dayton
- Point of interest: The existence of this route was in doubt as late as February 1920, as the Webster and Boone county supervisors, along with the towns of Dayton and Lehigh, tussled over the north-south route. That month, in what the Lehigh Valley Argus called "the thoroughly disorganized method of proceeding with the good roads question" (Feb. 26), Webster County overwhelmingly crushed road and bond propositions.
- In the same issue, Argus readers also found out they were getting a new state park, now known as Dolliver State Park. The park would later get its own little spur, IA 121.
WEST End: IA 90, now IA 175 at US 169, Webster County
IA 91 is one of many routes entirely or partially consumed by IA 175. When that route was extended west from Stratford, that also entitled the state to build a new Des Moines River bridge, the only such one between Fort Dodge and Boone.
EAST End: Dayton, Webster County
The earliest document available has a construction project from Harcourt to Dayton ending on the north side of Dayton, at the intersection of P73 and 6th Avenue. Paving into town 1932 put the east end at Skillet Street at High Street. However, sometime after that, Dayton renamed its streets and Skillet Avenue ("Street" could have been a map error in 1932) now intersects 1st Street NW in that location, a block west of downtown and where IA 175 turns south again. The Dayton Light and Power building, almost certainly a New Deal project, is a block south of that on Main. (7/25/12)
