Work is scheduled to begin on the North Grandview Avenue/University Avenue roundabout project, Dubuque’s second modern roundabout, on Thursday, June 7, but traffic will not be affected until the following week.

The Dubuque City Council and Iowa Department of Transportation approved plans to convert the intersection to a single-lane roundabout and the project was recently awarded to Eastern Iowa Excavating and Concrete, LLC.  The contractor anticipates some off-street construction work to begin on Thursday, June 7, with road closures/detours scheduled to begin on Thursday, June 14.

The project will require some traffic disruptions, but North Grandview Avenue will remain open to northbound and southbound traffic throughout construction.  Eastbound and westbound University Avenue traffic will be detoured along Delhi Street during construction.  Access to the businesses around the intersection and the fire station will be maintained throughout the entire project. The majority of the project will be completed before school resumes in August.

The roundabout was designed to work in conjunction with the existing roundabout to the south and the new traffic signals project to the north at North Grandview Avenue and Loras Boulevard intersection.  For more information, visit or call the City of Dubuque Engineering Department at 563-589-4270.
