Project location

US 18/151, US 18/151 (Dodgeville) to County MV (Verona), Dane and Iowa counties.

Project overview

  • US 18/151 is an important roadway connecting the major Midwest cities of Dubuque, Iowa and Madison, Wisconsin and is identified as a Backbone Route in WisDOT's Connections 2030 Plan.
  • The plan places high priority in protecting these highway investments that connect major economic/population centers and carry long-distance, statewide traffic.
  • The purpose of this study is to develop a long-term highway plan for converting this 28 mile portion of US 18/151 to a freeway.
  • The Study will result in a plan for the eventual removal of all direct access by existing local roads and driveways onto US 18/151.
  • This study is focusing on identifying and planning improvements to long-term access to and from the corridor, not adding additional capacity (travel lanes on US 18/151).


Environmental Study completed May 2014, with construction activity in Ridgeway scheduled for 2017. (see Study Section 2 on Maps pg. for details)
