It has been a tough winter for INDOT.
Spokesman Will Wingfield says they typically spend about $33.8 million for the entire winter.
However, he says they've already spent $31 million with two more months of winter still ahead.
Wingfield says the money went toward manpower, overtime, fuel, salt, equipment and other items to treat and maintain roads.
Wingfield says their snow plows have driven 4.3 million miles and dropped 265,000 tons of salt on highways this winter.
