Southwest Arterial (U.S. 52) Project

The Southwest Arterial (U.S. 52) is a 6.1-mile, four-lane, divided freeway with priority-one access control and provides an alternative route for traffic through southwestern Dubuque. It connects 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. After years of planning and construction, the Southwest Arterial opened in August 2020.

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) identified the completion of the Southwest Arterial (U.S. 52) Project as the #1 surface transportation priority in the Dubuque area.
