Wisconsin Highway 189 (WIS 189) was a short state highway in Wisconsin. It traveled from WIS 36/WIS 83 in Rochester to WIS 20.[1]
Starting at its western terminus, WIS 189 traveled eastward from WIS 36/WIS 83. Continuing east, it shortly ended at WIS 20 east of Rochester.[1]
In 1947, WIS 189 was formed as a result of WIS 20 being diverted and extended west. It traveled between WIS 36/WIS 83 and WIS 20 at a short distance.[1] During its existence, no significant changes were made.[3] By 1969, the route became decommissioned.[2] Today, the former route is now part of CTH-D.[4]
