On January 1, 2024, the Wisconsin Department of Transportation (WisDOT) convened the Transportation Projects Commission (TPC) to discuss critical infrastructure improvements aimed at enhancing road safety and reducing traffic-related injuries across the state. The meeting highlighted several key projects that promise to significantly lower crash rates and improve overall traffic flow.

A central focus of the discussions was the anticipated impact of upcoming projects on mainline crash rates. Officials projected a reduction of approximately 11 to 13% in injury crashes, translating to about 30 to 35 fewer injuries annually. This optimistic outlook is based on data from recently completed projects, such as improvements along I-39 and I-94, which have seen crash rate reductions of 25% and 14 to 20%, respectively. The TPC emphasized a conservative approach in their estimates, hoping that actual improvements may exceed these projections.

Specific interchanges were also identified for modernization, with the goal of further decreasing crash rates. For instance, enhancements at the US 12 interchange near Scott's and Dell's are expected to reduce fatalities by around 20%. The Cascade Mountain Road interchange, which has been flagged for safety issues, will be removed entirely, thereby eliminating associated crashes. Additionally, the busy intersection at Wisconsin 19 in the DeForest-Windsor area is projected to see a 50% reduction in crashes following improvements.

The meeting also addressed the challenges posed by heavy traffic volumes and complex lane changes, particularly in high-traffic areas like the I-39 and I-94 interchange. With thousands of vehicles navigating these roads during peak hours, the potential for accidents increases significantly. To mitigate these risks, the proposed build alternative includes the creation of collector-distributor lanes, which will separate on and off-ramp movements from the mainline traffic, thereby enhancing safety and efficiency.

In conclusion, the TPC meeting underscored WisDOT's commitment to improving road safety through targeted infrastructure projects. As these initiatives move forward, the anticipated reductions in crash rates and injuries will not only enhance public safety but also contribute to smoother traffic flow across Wisconsin's roadways. The next steps will involve finalizing project plans and securing necessary funding to bring these improvements to fruition.
