The Illinois Department of Transportation is asking lawmakers for another $47 million to cover the costs of the especially harsh winter.  Tony Small is the agency’s director of finance and administration.  He told a House committee Wednesday that this winter has “impacted IDOT operations tremendously.”  The Springfield State Journal-Register reports the extra costs include overtime, additional road salt and fuel, as well as the hiring of temporary workers.  Small said the agency will use 1 million tons of salt this winter, more than the previous two winters combined.  The old record was 840,000 tons.  The House Public Safety Appropriations Committee made no immediate decision Wednesday on the supplemental spending request.
