Located in Wrightsville, Pennsylvania, along the Susquehanna River, County Line Quarry was established in 1929 to provide construction aggregates to the surrounding areas of York and Lancaster counties.
County Line Quarry is a PennDot and AASHTO approved source for crushed stone. Lighter weight quartz phyllite is harder and more durable than comparable crushed stone, with an excellent skid resistance level, which means safer roadway surfaces and more volume of material per ton.
County Line offers a complete range of sizes from mineral filler to rip rap, with specialty aggregates also available. Some specialty items include DEP Sand, Non-Carbonate Landfill Stone, and the only locally available SRL E-Rated asphalt aggregates.
