Mercer County Landfill

Mercer County Landfill on Frontage Road in Princeton is the county landfill where household and commercial loads get buried. Pickup trucks, trailers and big haulers all use this spot, so expect a mix of small vehicles and heavy trucks.

There’s usually an entrance booth and at least one scale-landfills commonly charge tipping fees by weight or by set load rates, so plan for a weigh-in and weigh-out. After weighing, drivers head to the active tipping area to unload; the site is mostly open earth cells, mounds of cover material, gravel roads and heavy equipment moving around. Commercial loads are typically accepted at county landfills, but exact fees and acceptable materials depend on local and state rules. Weekends, especially during spring cleanup, get backed up, so allow extra time if hauling on busy days.
