Millwork District Street Redevelopment

IIW designed a two-way street conversion in accordance with the city’s master plan to better facilitate truck traffic and avoid the confusion and out of the way travel needed to access some areas within Historic Millwork District in Downtown Dubuque.

The master plan identified streets that allowed for two-way traffic as more appropriate for the redevelopment of the Historic Millwork District.

IIW prepared plans to convert 9th Street, 11th Street, Elm Street and Pine Street from one-way roadways in Dubuque’s Historic Millwork District into two-way roadways. This project involved portions of U.S. Highway 61/151 and U.S. Highway 52 and required coordination with the Iowa Department of Transportation. It included traffic modeling to verify the use of two-way streets would serve the traffic needs.

From pavement reconstruction, a sidewalk addition and storm sewer adjustments to provision for fiber optic conduits, streetlights and traffic signals, IIW led the modifications to the roadway network. Appealing to the historic nature and pedestrian traffic, IIW also included pavers at an intersection in the Historic Millwork District.

IIW prepared the construction plans for the project, including all signing and pavement marking changes to allow the conversion of streets from a one-way traffic pattern to a two-way roadway. The design included the redesign of intersections that accommodate the turning movements of semi-trucks.

While designing the reconstruction of Elm Street, IIW also considered the addition of an Intermodal Facility where transit busses and intercity busses would use a new Intermodal Terminal Building on the east side of Elm Street. The Elm Street design accommodated the bus turning movements and access points as well as pedestrian access to the Intermodal Terminal building.
