Another long-standing structure in the Heritage District went down Thursday morning. The former Pinal County Sheriff’s Office substation that most recently served as the F.O.R. Maricopa Food Bank was turned into scrap while subcontractor Breinholt Construction also scooped up the pavement of the parking lot. Former fire department administration buildings in the same lot are next on the list as the Arizona Department of Transportation prepares for Ames Construction to begin work on a new overpass across the railroad bridge. Earlier this week, Spoon’s diner, the Copa Center and other structures were demolished.
