The Pennsylvania Department of Transportation said it's supplied about 6,000 tons of road salt to municipalities that have run short this winter.
The highway department said Monday its salt stock stood at about 382,000 tons, with some 145,000 tons still to be delivered.
In an average winter, PennDOT goes through about 800,000 tons, but this year's series of storms has the department going through road salt more quickly than usual.
So far this season, it's loaned salt to Pittsburgh, Philadelphia, New Castle and the suburban Philadelphia community of Upper Gwynedd Township.
PennDOT starts each winter with more than 500,000 tons on hand.
