Southwest Arterial(U.S. 52) Project


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