Study location

This study is located on US 12, from the Parmenter Street interchange just north of Middleton to WIS 19 west in the town of Springfield, in Dane County.

Study overview

This 6.1 mile corridor of US 12 is part of Wisconsin’s National Highway System (NHS).

This corridor provides a parallel route from the Madison metro area to I-39/90/94 and to the major tourism destination area in the state and region and to Wisconsin Dells.

This study will help increase highway functionality and safety along corridor.

The existing expressway was finished in 2005. Dane County’s North Mendota Parkway Study intends to tie into US 12 for the western termini.
