The Chestnut Street project led the Wisconsin Department of Transportation, Grant County, the City of Platteville and University of Wisconsin – Platteville to partner with Origin Design to develop and execute a plan to provide a more direct route to the university.
Providing a more direct route to University of Wisconsin – Platteville led to the street reconstruction and replacement of the Chestnut Street Rountree Branch Bridge and 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.
The project did not come without its challenges. The realignment of the half-mile of roadway also required Section 106, Phase I Hazardous Materials Assessment and Environmental Report. Origin Design coordinated the work with multiple of consultants. This ARRA funded project also needed to be complete in nine months while including public involvement to meet the funding requirements.
Origin Design’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.
With a focus on enhanced pedestrian mobility in the area, the bridge includes two travel lanes, a bike lane, multiuse trail and sidewalk.
The quality of the newly designed structure earned the project the WisDOT Excellence in Highway Design Award.
