The Chestnut Street project led IIW to partner with the Wisconsin Department of Transportation, Grant County, the City of Platteville and University of Wisconsin – Platteville to develop and execute a plan to provide a more direct route to the university. This included incorporating a roundabout at the intersection where traffic chooses between Downtown Platteville versus the University as a destination.

This 0.45-mile street reconstruction and bridge replacement project over Rountree Branch features the use of a two-span 100-foot structure designed to replicate a limestone arch. With a focus on enhanced pedestrian mobility in the area, the bridge includes two travel lanes, a bike lane, multiuse trail and sidewalk.

The realignment caused the project to require a Section 106, Phase I Hazardous Materials Assessment, and Environmental Report. The project required coordination related to three 4(f) issues.

IIW’s professional services covered multiple aspects of the design process, including a roundabout, on-street bike lanes, grading, storm sewer, lighting, modular block retaining walls, water main, sanitary sewer main, asphaltic surfaced trail, settlement basins, pavement marking, signing, and fencing.
