WIS 69, County D to Valley Road

Dane County

PROJECT PROFILE

Corridor Modernization

Despite challenging space constraints and an aggressive timeline, the team successfully delivered a solution that significantly improved public safety, reduced traffic congestion, and balanced the needs of the client, WisDOT, and stakeholders while remaining on time and under budget.
The Opportunity

JT took on the WIS 69 corridor modernization and rehabilitation project between Belleville and Verona, addressing roadway upgrades, ADA compliance, intersection safety, and flooding issues. The team faced complex environmental challenges, including extensive archaeological investigations, historical properties, hazardous materials, and impacts on wetlands and parklands. Proactive public outreach and stakeholder engagement were crucial for the project’s success.

The Outcome

The project delivered a modernized roadway with improved safety features and flood resilience. A single-lane roundabout was implemented at the County PB intersection, and a flood-prone segment was raised above the 100-year flood elevation. Proactive outreach efforts streamlined stakeholder understanding and property negotiations, with concerns addressed through direct meetings.

Award Winning

In 2024, the WIS 69 project won as WisDOT’s Best Rural Design by a Consultant Award and was also recognized with an ACEC-Wisconsin State Finalist Design Award.

Notable Safety Upgrade

A single-lane roundabout replaced the existing four-way stop at the County PB intersection. The modern design features high-speed approaches and accommodates anticipated through movements for oversized and overweight vehicles on WIS 69.

Overcoming challenges
Flood-Resilient Roadway Design

The project addressed major drainage issues throughout the project limits, with the most significant issue being the recurring flooding north of Paoli that had previously overtopped and washed out three times in two years. The design addressed this by raising the roadway elevation above the 100-year flood level and reconfiguring cross pipes and ditches for faster flood relief. Collaboration with WisDOT Central Office experts ensured practical solutions to prevent future flooding impacts on the roadway.

Overcoming Environmental Challenges

Despite numerous environmental issues, such as extensive archaeological investigations (the investigations discovered materials that made numerous sites potentially eligible for the National Register of Historic Places), historical properties, hazardous materials, and parkland impacts, the project team addressed all concerns through direct meetings and diligent coordination with stakeholders, agencies, and environmental representatives.
