Wisconsin uses salt brine instead of rock salt, cutting usage by 40%–72% and improving road safety.
A University of Wisconsin study confirms salt brine is as effective as rock salt for winter road maintenance while reducing salt use by 40% to 72%.
The research, conducted by the Traffic Operations and Safety Laboratory, found brine prevents ice from bonding to pavement, improves salt efficiency, and allows $1,000 worth of salt to treat over 175 miles of road—compared to 70 miles with dry salt.
All 72 Wisconsin counties now use brine to stretch budgets, enhance safety, and reduce environmental impact, supporting the state’s push for more efficient winter road treatment.
