WIS 127 is maintained by the Wisconsin Department of Transportation (WisDOT).

It enters the Town of Lewiston, passing to the south of Lake Corning.

WIS 127 crosses a creek before turning east to pass Lewiston Elementary School.

The highway curves south to pass Columbia Correctional Institution, a maximum-security state prison, before entering Portage.

[4][5] The route then became portions of CTH-WD and CTH-AA before re-entering the Wisconsin State Trunk Highway System in 1956, when WIS 127 was established.
