It begins at U.S. Route 218 (US&nbsp;218) in Vinton and ends at US&nbsp;52 and Iowa&nbsp;24 in Calmar. From Vinton, it heads north and east towards Urbana where it meets Interstate 380 (I-380) and Iowa&nbsp;27, the Avenue of the Saints highway. At Independence, it intersects US&nbsp;20 on the south side of town. Further north, it converges with Iowa&nbsp;3 in Oelwein.

As it traverses through the east-central part of the state, Iowa&nbsp;150 mostly passes through farmland where acreages and farmsteads dot the landscape. Through the towns along the route, the highway generally brings traffic through the central business districts of each town. In Fayette however, the highway bypasses the downtown area. Between Fayette and West Union, part of the route forms the western leg of the River Bluffs Scenic Byway, which passes through Iowa's "Little Switzerland" region.

The Iowa&nbsp;150 designation has been a part of the primary highway system since its inception in 1920. The current route was formed in 1941. The route extended from Calmar to Davenport, by way of Cedar Rapids. In 1969, the route was truncated at Cedar Rapids, with part of the old route becoming Iowa&nbsp;130. In 1984, it took its current form when the southern part of the route was shifted over the former '''Iowa&nbsp;101'''. Most of the abandoned part of Iowa&nbsp;150 became '''Iowa&nbsp;920''' until July 1, 2003.

==Route description== Iowa&nbsp;150 begins at a T intersection with US&nbsp;218 on the southern side of Vinton. US&nbsp;218 comes up from the south and turns west at the intersection while Iowa&nbsp;150 begins heading north along C Street. Near downtown, the highway turns to the east for a few blocks. At the Benton County Courthouse, it turns north once again and almost immediately crosses the Cedar River. North of Vinton, the highway passes a small airport surrounded by fields and then curves to the east for a few miles. West of Urbana, it heads back to the north and intersects Interstate 380 (I-380).<ref name="2012 DOT map">{{cite map|publisher=Iowa Department of Transportation|title=Transportation Map|url=http://www.iowadotmaps.com/msp/pdf/current/stmapmain.pdf|year=2012|section=J5–K7|access-date=April 9, 2012|format=PDF}}</ref> thumb|left|Iowa Highway 150 crosses the Wapsipinicon River in Independence.

The highway heads due north, only passing a few houses until it reaches US&nbsp;20 south of Independence. Once in Independence, it crosses the Wapsipinicon River over a concrete arch bridge.

North of Independence, Iowa&nbsp;150 continues north through the farmland of rural Buchanan County. It passes through Hazleton a few miles before it meets Iowa&nbsp;281 south of Oelwein. North of Iowa&nbsp;281, which runs along the Buchanan–Fayette county line, Iowa&nbsp;150 enters Oelwein along Rock Island Road, which eases into 1st Avenue. A block east of downtown, at Charles Street, Iowa&nbsp;3 approaches from the east and turns north onto Iowa&nbsp;150. The two routes head through Oelwein along Frederick Avenue and split a couple miles north of town.<ref name="Oelwein map">{{cite map|publisher=Iowa Department of Transportation|title=Highway and Street Map|url=http://www.iowadot.gov/maps//msp/citypdf/Oelwein_ci.pdf|access-date=April 9, 2012|date=January 25, 2011|series=Oelwein, Iowa|format=PDF}}</ref> The highway turns east very briefly and returns heading north until it reaches Fayette County Road C33 (CR&nbsp;C33).

Iowa&nbsp;187 comes from the south and ends at the intersection, while Iowa&nbsp;150 turns north and continues towards Fayette.<ref name="2012 DOT map" />

At Fayette, the home of Upper Iowa University, Iowa&nbsp;150 intersects Iowa&nbsp;93 and crosses the Volga River on the north side of town. Between Fayette and West Union, the highway forms the western leg of the River Bluffs Scenic Byway, through the area known locally as "Little Switzerland".<ref name="River Bluffs">{{cite web|url=http://www.iowadot.gov/iowasbyways/river_bluffs.pdf|title=River Bluffs Scenic Byway|publisher=Iowa Department of Transportation|access-date=April 9, 2012}}</ref> In West Union, the route meets the western end of Iowa&nbsp;56 on the south side and then US&nbsp;18 in the heart of town. North of West Union, the route gradually eases to the west through a series of curves. South of the unincorporated community of Festina, the route straightens out on its way to Calmar. As Iowa&nbsp;150 comes up from the south, the route ends in Calmar at an intersection with US&nbsp;52, which comes in from the east and turns north, and Iowa&nbsp;24, which comes in from the west.<ref name="2012 DOT map" />

==History== There have been three iterations of Iowa&nbsp;150 that have been shown on maps since the primary highway system was created in 1920. The first, designated in 1925, was a short connector route between US&nbsp;32 in Homestead and US&nbsp;30 in Cedar Rapids.<ref name="ISHC bulletin">{{cite book|last=Iowa State Highway Commission|title=Service Bulletin|series=Nos. 10-11-12|volume=XIII|date=Oct–Dec 1925|page=9}}</ref> This route that later became part of Iowa&nbsp;149 is currently part of US&nbsp;151.<ref name="2012 DOT map" />

===Current route=== The current Iowa&nbsp;150 was created shortly after Iowa&nbsp;17 supplanted the former Iowa&nbsp;150 in the west-central part of the state. The new Iowa&nbsp;150 replaced Iowa&nbsp;11, which stretched from Calmar to Cedar Rapids via Independence, in its entirety.<ref name="DOT1942" /><ref name=DOT1941>{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1941-front.pdf|title=Iowa State Highway Map|year=1941|section=C20–I21|access-date=April 21, 2012|format=PDF}}</ref> Through Cedar Rapids, the highway entered from the north along Center Point Road NE. It turned west onto US&nbsp;151 and Iowa&nbsp;64 along 1st Avenue E near Coe College.

Further into town, it intersected Kimberly Road and then transitioned onto Harrison Street.

During the 1950s, as today's highway system was beginning to take shape, Iowa 150 was rerouted a couple times in Cedar Rapids. The first adjustment happened in 1954, when US&nbsp;30 was taken off of Mount Vernon Road and put onto a new road on the south side of town. Iowa&nbsp;150 was moved west through downtown and across the Cedar River. It turned south onto 6th Street SW, on which US&nbsp;30 and US&nbsp;218 joined at 18th Avenue SW. The three routes turned east onto the new road, but US&nbsp;218 turned south at Bowling Street SW.<ref name=DOT1955CR>{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1955_back.pdf|title=Iowa State Highway Map|year=1955|access-date=April 24, 2012|format=PDF|inset=Cedar Rapids}}</ref> Within five years, Iowa&nbsp;150 moved to the northeast side of Cedar Rapids and into Marion. Instead of continuing south to Coe College, it turned east at Collins Road and connected with US&nbsp;151 and Iowa&nbsp;64 near the eastern city limits. It then followed those two routes to downtown Marion, where it turned south onto a road which headed southeast towards Mount Vernon.<ref name=DOT1959CR>{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1959_back.pdf|title=Iowa State Highway Map|year=1959|access-date=April 24, 2012|format=PDF|inset=Cedar Rapids}}</ref> East of Mount Vernon, it followed US&nbsp;30 to Iowa&nbsp;38 and continued towards Davenport.<ref name=DOT1959>{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1959_front.pdf|title=Iowa State Highway Map|year=1959|section=J22–K24|access-date=April 24, 2012|format=PDF}}</ref> Within a few years, Iowa&nbsp;150 was rerouted onto the newly extended Iowa&nbsp;13, which was extended south to US&nbsp;30 near Bertram.<ref name=DOT1962CR>{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1962_back.pdf|title=Iowa State Highway Map|year=1962|access-date=April 28, 2012|format=PDF|inset=Cedar Rapids}}</ref> At its longest extent, the route was {{convert|180.52|mi}} long.<ref name="ISHC 1965" />

That all changed on January 1, 1969, when the Iowa State Highway Commission reorganized its primary highway system.

The southern end of Iowa&nbsp;150 changed again in 1984. After I-380, which was constructed parallel to Iowa&nbsp;150 between Cedar Rapids and Center Point, was opened to traffic, Iowa&nbsp;150's routing south of Iowa&nbsp;101 was essentially redundant to the new interstate. As a result, Iowa&nbsp;150 was rerouted over Iowa&nbsp;101 south to Vinton.<ref name=DOT1983>{{cite map|publisher=Iowa Department of Transportation|url=http://www.iowadotmaps.com/msp/historical/pdf/1983_front.pdf|title=Iowa State Highway Map|year=1983|section=H4–I5|access-date=April 30, 2012}}</ref><ref name=DOT1986>{{cite map|publisher=Iowa Department of Transportation|url=http://www.iowadotmaps.com/msp/historical/pdf/1986_front.pdf|title=Iowa State Highway Map|year=1986|section=H4–I5|access-date=April 30, 2012}}</ref> The vacated section of Iowa&nbsp;150 was renumbered Iowa&nbsp;920 from old Iowa&nbsp;101's north end to Center Point and Iowa&nbsp;921 from Center Point to Cedar Rapids.<ref name="Iowa DOT 1984">{{IowaDOT|2012-04-25|year=1984|link=no}}</ref>

In the 1980s, Iowa&nbsp;150 near Oelwein was rerouted onto a new section of highway along the former right-of-way of the recently liquidated Rock Island Railroad. Originally proposed as a four-lane highway, pressure from Oelwein residents caused the Iowa Transportation Commission to approve a three-lane highway instead.<ref>{{cite news|url=https://news.google.com/newspapers?id=mnNjAAAAIBAJ&pg=6014%2C1915369|title=Rail route for Oelwein road|date=October 15, 1980|work=Telegraph-Herald|access-date=April 18, 2012|location=Dubuque, Iowa|agency=UPI}}</ref> The new section of highway was open by 1986.<ref name="DOT1986" /> The old section of Iowa&nbsp;150 remained on the primary highway system as the unsigned Iowa&nbsp;916 until July 1, 2003.<ref name="Iowa DOT 2002" />

In 2002, the Road Use Tax Fund Committee, a mix of city, county, and state transportation officials, met to review and recommend changes to Iowa's public road system.

The committee identified over {{convert|700|mi}} of state highways, including Iowa&nbsp;920, which could be turned over to local jurisdictions.<ref name=archive2>{{cite web |last1=Reeder |first1=Greg |last2=Stevens |first2=Larry |last3=Fichtner |first3=Royce |last4=Stoner|first4=Tom|last5=Wandro|first5=Mark|last6=Volmer |first6=Neil |url=http://publications.iowa.gov/1147/1/rutf_committee_report.pdf |title=Evaluation of the State Highway System and Road Use Tax Fund |publisher=State of Iowa |access-date=April 18, 2012 |date=April 1, 2003}}</ref> Most of the committee's recommendations were accepted and on July 1, 2003, Iowa&nbsp;920 and over {{convert|600|mi}} of state highways were turned over to the counties or local jurisdictions.<ref name=Senate1>{{cite web |url=http://www.legis.state.ia.us/GA/80GA/BillHistory/SF/00400/SF00451.html |title=BH SF 0451 |access-date=April 18, 2012 |date=June 24, 2003 |archive-date=May 13, 2007 |archive-url=https://web.archive.org/web/20070513131328/http://www.legis.state.ia.us/GA/80GA/BillHistory/SF/00400/SF00451.html |url-status=dead}}</ref> The east–west portion near Walker was replaced by CR&nbsp;D62, while the north–south portion became CR&nbsp;W6E.<ref name="2012 DOT map"/>
