The $45 billion construction plan is being paid for by revenue from tax increases on gas and cigarettes and expanded gambling, including new casinos in Chicago and the suburbs and legalized sports betting. A total of $33 billion in funding will go to transportation, of which almost 23 percent will go to transit. The state’s 19-cent-per-gallon motor fuel tax, last raised in 1990, doubled to 38 cents per gallon and will be indexed to future inflation increases.
