Litter on state roadsides in several county towns is evident  with the coming of spring.  According to Beaver County Radio News Correspondent Sandy Giordano, local police that were contacted said that the task is up to PennDOT. A PennDOT  spokesperson contacted yesterday said the state  road cleanups are seasonal. Several listeners who called in to Teleforum on Beaver County Radio complained to guest show host Frank Sparks about the littered roadsides.
