US 18/151 is an important roadway connecting the major Midwest cities of Dubuque, Iowa and Madison, Wisconsin. US 18/151 is identified as a Backbone Route in the Wisconsin Department of Transportation's (WisDOT)
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).
