Route description
Iowa 160 begins at an intersection with Iowa 415 in southwestern Ankeny. Iowa 415 comes from the south and the west, Iowa 160 begins heading east, and Ankeny's State Street continues north. Iowa 160, known locally as Oralabor Road, passes to the south of the main campus of Des Moines Area Community College (DMACC). A short while later, it intersects US 69, also known as Ankeny Boulevard. Continuing east, it enters a dense commercial area of Ankeny. It passes beneath a pedestrian bridge built in 2022 as an extension of the High Trestle Trail.{{cite news |last1=Mercado |first1=Melody |title=Ankeny OKs capital improvement plan |url=https://www.newspapers.com/clip/118338618/ankeny-oks-capital-improvement-plan/ |access-date=February 10, 2023 |work=The Des Moines Register |date=January 4, 2021 |pages=C1, C6 |via=Newspapers.com}} {{open access}}{{cite news |last1=Mollenbeck |first1=Andrew |title=New bridge in Ankeny will connect three popular trails |url=https://www.kcci.com/article/new-iowa-bridge-in-ankeny-will-connect-three-popular-trails/39996669 |access-date=February 10, 2023 |agency=KCCI-TV |date=May 13, 2022 |archive-url=https://web.archive.org/web/20220514030743/https://www.kcci.com/article/new-iowa-bridge-in-ankeny-will-connect-three-popular-trails/39996669 |archive-date=May 14, 2022 |location=Des Moines |language=en}} Just {{convert|0.3|mi|m}} from its eastern end, it intersects Delaware Avenue, a north–south street which diverts retail traffic exiting from I-35 just to the east.

History
Iowa 160 was designated in 1947 as a diagonal connector route from Iowa 60, now Iowa 415, to US 69.{{cite map|publisher=Iowa State Highway Commission|url=http://www.iowadotmaps.com/msp/historical/pdf/1948-front.pdf|title=Iowa State Highway Map|year=1948|access-date=February 19, 2012|format=PDF}} The roadway was originally constructed in 1942 as a connector to the Des Moines Ordnance Plant. It was built by the Iowa State Highway Commission, but the entire costs were borne by the federal government as part of the war effort. In 1961, work began on reconstructing the intersection with Iowa 60 into a "one-level interchange", which provided each traffic movement a dedicated lane.{{cite news |last1=Mabry |first1=Drake |title=New Look on Second Avenue |url=https://www.newspapers.com/clip/118339540/new-look-on-second-avenue/ |access-date=February 10, 2023 |work=Des Moines Tribune |date=August 11, 1961 |pages=9 |via=Newspapers.com}} {{open access}}
That intersection was reworked starting in 1984 as the state highway commission, now the Iowa Department of Transportation (Iowa DOT), and United States Army Corps of Engineers (Corps) sought to improve the connection between I-35 and Iowa 415 and recreation areas near Saylorville Lake and Big Creek State Park. The plans would also move the intersection of Iowa 415 and Iowa 160 farther north from its location at the time and it would become a T intersection.{{cite news |last1=Bailey |first1=Phyllis |title=Ankeny motorists facing Highway 415, 160 detour |url=https://www.newspapers.com/clip/118340880/ankeny-motorists-facing-highway-415/ |access-date=February 10, 2023 |work=The Des Moines Register |date=November 7, 1984 |page=6N |via=Newspapers.com}} {{open access}}{{cite news |last1= |title=DOT to revamp intersection |url=https://www.newspapers.com/clip/118341061/dot-to-revamp-intersection/ |access-date=February 10, 2023 |work=The Des Moines Register |date=January 30, 1985 |page=14N |via=Newspapers.com}} {{open access}} On July 1, 1980, the Iowa DOT took over a {{convert|1|mi|km|adj=on|spell=in}} segment of Oralabor Road between US 69 and I-35 and applied the Iowa 160 designation to it.{{cite web |last1=Cain |first1=Patrick R. |title=Commission Order |url=https://iowadot.gov/analytics/PrimaryRteDescrips/Polk/IA%20160.htm |publisher=Iowa Department of Transportation |access-date=February 10, 2023 |location=Ames |date=February 17, 1981}} Through most of 1985, the Oralabor Road interchange on I-35 was closed for reconstruction. That same year, Oralabor Road was widened to four lanes between US 69 and Delaware Avenue.{{cite news |last1=Bailey |first1=Phyllis |title=Ankeny Industrial Exit on I-35 closing for work |url=https://www.newspapers.com/clip/118341400/ankeny-industrial-exit-on-i-35-closing/ |access-date=February 10, 2023 |work=The Des Moines Register |date=March 20, 1985 |page=7N |via=Newspapers.com}} {{open access}} As part of the Iowa 415 connection project, the Corps spent $9.95 million (equivalent to ${{format price|{{inflation|US-GDP|9950000|1986}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}) on building the new intersection and relocating the two state highways.{{cite news |last1= |title=Corps plans to straighten stretch of Highway 415 |url=https://www.newspapers.com/clip/118341209/corps-plans-to-straighten-stretch-of/ |access-date=February 10, 2023 |work=The Des Moines Register |date=November 5, 1986 |page=1N |via=Newspapers.com}} {{open access}} The new Iowa 415/Iowa 160 intersection was completed in early 1986 and both highways were realigned onto to their current roadways.{{cite web |last1=Cain |first1=Patrick R. |title=Staff Order |url=https://iowadot.gov/analytics/PrimaryRteDescrips/Polk/IA%20160.htm |publisher=Iowa Department of Transportation |access-date=February 10, 2023 |location=Ames |date=June 4, 1987}}
