WIS 23, WIS 11 to Mineral Point
City of darlington
Historic Downtown Revitalization


The state highway at the heart of the City of Darlington was rapidly failing. Increased demand was crushing a transportation corridor suffering from an outdated design, frequent flooding, and crumbling pavement. The project faced numerous challenges, including a deteriorated storm sewer system, a single bridge connecting the city, outdated pedestrian accommodations, and flooding issues due to the Pecatonica River and FEMA-mapped floodplain.
Through meticulous planning and creative problem-solving, JT delivered a revitalized WIS 23 that caters to various users while addressing the community’s concerns. The updated roadway boasts a durable pavement structure, improved pedestrian safety, and better accommodations for diverse vehicles, including ATVs, trucks, and oversize-overweight vehicles.

The project also enhanced the historic downtown streetscape, updated storm sewer networks, and replaced lead pipes for safer drinking water. WisDOT and the City of Darlington now have a roadway to be genuinely proud of, with lasting benefits for residents and businesses for years to come.



Located in a floodplain near the Pecatonica River, it was crucial to ensure the only in-town river crossing remained accessible during construction. The project team achieved this through effective construction staging and temporary signals.

The design team expertly integrated the new roadway with the existing environment, protecting critical resources and historic properties. Refined horizontal and vertical design avoided impacting the downtown district and NRHP buildings. Utilizing parking limitations, the team created a safer, aesthetically pleasing streetscape with reduced impacts on nearby homes.
