Southwest Arterial Project

The Southwest Arterial will be a 6.1-mile, four-lane, divided freeway with priority-one access control
and will provide an alternative route for traffic through southwestern Dubuque. It will connect the
Dubuque Technology Park on U.S. Hwy 61/151 with the new Dubuque Industrial Center West and the
existing Dubuque Industrial Center near U.S. Hwy 20.
The Dubuque City Council, the Dubuque County Board of Supervisors, Dubuque Area Chamber of
Commerce, Greater Dubuque Development Corporation, and Dubuque Metropolitan Planning
Organization (DMATS) have identified the completion of the Southwest Arterial Project as the #1
surface transportation priority in the Dubuque area.
The City of Dubuque, Dubuque County, and the Iowa Department of Transportation have committed
funding for the continued development and completion of the Southwest Arterial. To obtain
