Work has started on converting more than 600 state highway department trucks and cargo vans in Indiana so that they run on propane and use what officials predict will be about 500,000 fewer gallons of gasoline or diesel fuel a year.
The infrastructure for 115 fueling site across the state is already in place, said Lt. Gov. Becky Skillman, who highlighted the project during a visit Monday to a state highway department garage in Fort Wayne where one of the fueling stations is located.
