Dodge County will be reducing the amount of road salt being used because of dwindling supplies. Highway Commissioner Brian Field says salt orders are not being fulfilled due to extreme weather conditions on the Great Lakes and the nation-wide demand for salt this winter season. Field says the state has directed counties to reduce the amount of salt used on state trunk highways. Primary routes including highway’s 151, 33, 26 and 41 will see 200 pounds of salt applied per lane per mile, down from 300 pounds. On all other state routes handled by the county, only 100 pounds of salt will be used. In the event of freezing rain, the salt usage will increase back to 300 pounds per mile on major thoroughfares and 200 pounds on secondary roads. The state is telling counties officials to use more sand and place a greater reliance on mechanical means, using plows to scrape snow and ice. On Tuesday, officials in Beaver Dam said they were adding more sand to their applications as 90-percent of the city salt supply has already been used.
